===============================================================================
Phasing out MTRR use
-MTRR use is replaced on modern x86 hardware with PAT. Direct MTRR use by
-drivers on Linux is now completely phased out, device drivers should use
-arch_phys_wc_add() in combination with ioremap_wc() to make MTRR effective on
-non-PAT systems while a no-op but equally effective on PAT enabled systems.
-
-Even if Linux does not use MTRRs directly, some x86 platform firmware may still
-set up MTRRs early before booting the OS. They do this as some platform
-firmware may still have implemented access to MTRRs which would be controlled
-and handled by the platform firmware directly. An example of platform use of
-MTRRs is through the use of SMI handlers, one case could be for fan control,
-the platform code would need uncachable access to some of its fan control
-registers. Such platform access does not need any Operating System MTRR code in
-place other than mtrr_type_lookup() to ensure any OS specific mapping requests
-are aligned with platform MTRR setup. If MTRRs are only set up by the platform
-firmware code though and the OS does not make any specific MTRR mapping
-requests mtrr_type_lookup() should always return MTRR_TYPE_INVALID.
+MTRR use is replaced on modern x86 hardware with PAT. Over time the only type
+of effective MTRR that is expected to be supported will be for write-combining.
+As MTRR use is phased out device drivers should use arch_phys_wc_add() to make
+MTRR effective on non-PAT systems while a no-op on PAT enabled systems.
For details refer to Documentation/x86/pat.txt.

Subject: [PATCH] ACPICA: Events: Fix acpi_ev_initialize_region() return value
ACPICA commit 543342ab7a676f4eb0c9f100d349388a84dff0e8
This patch changes acpi_ev_initialize_region(), stop returning AE_NOT_EXIST
from it so that, not only in acpi_ds_load2_end_op(), but all places invoking
this function won't emit exceptions. The exception can be seen in
acpi_ds_initialize_objects() when certain table loading mode is chosen.
This patch also removes useless acpi_ns_locked from acpi_ev_initialize_region()
as this function will always be invoked with interpreter lock held now, and
the lock granularity has been tuned to lock around _REG execution, thus it
is now handled by acpi_ex_exit_interpreter(). Lv Zheng.

Subject: [PATCH] jbd2: Fix dbench4 performance regression for 'nobarrier' mounts
Date: Fri, 28 Apr 2017 11:59:34 +0200
Commit b685d3d65ac7 "block: treat REQ_FUA and REQ_PREFLUSH as
synchronous" removed REQ_SYNC flag from WRITE_FUA implementation. Since
JBD2 strips REQ_FUA and REQ_FLUSH flags from submitted IO when the
filesystem is mounted with nobarrier mount option, journal superblock
writes ended up being async writes after this patch and that caused
heavy performance regression for dbench4 benchmark with high number of
processes. In my test setup with HP RAID array with non-volatile write
cache and 32 GB ram, dbench4 runs with 8 processes regressed by ~25%.
Fix the problem by making sure journal superblock writes are always
treated as synchronous since they generally block progress of the
journalling machinery and thus the whole filesystem.
Fixes: b685d3d65ac791406e0dfd8779cc9b3707fea5a3

Subject: drm/i915: Remove WaDisableLSQCROPERFforOCL KBL workaround.
The WaDisableLSQCROPERFforOCL workaround has the side effect of
disabling an L3SQ optimization that has huge performance implications
and is unlikely to be necessary for the correct functioning of usual
graphic workloads. Userspace is free to re-enable the workaround on
demand, and is generally in a better position to determine whether the
workaround is necessary than the DRM is (e.g. only during the
execution of compute kernels that rely on both L3 fences and HDC R/W
requests).
The same workaround seems to apply to BDW (at least to production
stepping G1) and SKL as well (the internal workaround database claims
that it does for all steppings, while the BSpec workaround table only
mentions pre-production steppings), but the DRM doesn't do anything
beyond whitelisting the L3SQCREG4 register so userspace can enable it
when it sees fit. Do the same on KBL platforms.
Improves performance of the GFXBench4 gl_manhattan31 benchmark by 60%,
and gl_4 (AKA car chase) by 14% on a KBL GT2 running Mesa master --
This is followed by a regression of 35% and 10% respectively for the
same benchmarks and platform caused by my recent patch series
switching userspace to use the dataport constant cache instead of the
sampler to implement uniform pull constant loads, which caused us to
hit more heavily the L3 cache (and on platforms other than KBL had the
opposite effect of improving performance of the same two benchmarks).
The overall effect on KBL of this change combined with the recent
userspace change is respectively 4.6% and 2.6%. SynMark2 OglShMapPcf
was affected by the constant cache changes (though it improved as it
did on other platforms rather than regressing), but is not
significantly affected by this patch (with statistical significance of
5% and sample size 20).
v2: Drop some more code to avoid unused variable warning.

Subject: [PATCH] drm/i915: don't warn about Skylake CPU - KabyPoint PCH combo
Apparently there are machines out there with Skylake CPU and KabyPoint
PCH. Judging from our driver code, there doesn't seem to be any code
paths that would do anything different between SunrisePoint and
KabyPoint PCHs, so it would seem okay to accept the combo without
warnings.

Change History
--------------
v3:
- add Fixes and CC tags
- add link to Bugzilla
v2: changes suggested by Joerg
- add flush flag to improve efficiency of flush operation
v1:
- The idea behind flush queues is to defer the IOTLB flushing
for domains for which the mappings are no longer valid. We
add such domains in queue_add(), and when the queue size
reaches FLUSH_QUEUE_SIZE, we perform __queue_flush().
Since we have already taken lock before __queue_flush()
is called, we need to make sure the IOTLB flushing is
performed as quickly as possible.
In the current implementation, we perform IOTLB flushing
for all domains irrespective of which ones were actually
added in the flush queue initially. This can be quite
expensive especially for domains for which unmapping is
not required at this point of time.
This patch makes use of domain information in
'struct flush_queue_entry' to make sure we only flush
IOTLBs for domains who need it, skipping others.
Bugzilla: https://bugs.freedesktop.org/101029

Denys provided an awesome KASAN report pointing to an use
after free in xt_TCPMSS
I have provided three patches to fix this issue, either in xt_TCPMSS or
in xt_tcpudp.c. It seems xt_TCPMSS patch has the smallest possible
impact.

brcmf_sdio_fromevntchan() was being called on the the data frame

mischaracterized as on the event channel rather than the data channel.
This fixes a major performance regression (due to dropped packets).

From: Joerg Roedel <jroedel@suse.de>
ATS is broken on these devices. Under invalidation load, the
GPU does not reply to invalidations anymore, causing
Completion-wait loop timeouts on the AMD IOMMU driver side.
Fix it by not enabling ATS on these devices.
Note that below mentioned commit is not broken, it just
triggers the issue because it might cause invalidation
storms on devices.
Fixes: b1516a14657a ('iommu/amd: Implement flush queue')

Subject: [PATCH] pinctrl/amd: Use regular interrupt instead of chained
The AMD pinctrl driver uses a chained interrupt to demultiplex the GPIO
interrupts. Kevin Vandeventer reported, that his new AMD Ryzen locks up
hard on boot when the AMD pinctrl driver is initialized. The reason is an
interrupt storm. It's not clear whether that's caused by hardware or
firmware or both.
Using chained interrupts on X86 is a dangerous endavour. If a system is
misconfigured or the hardware buggy there is no safety net to catch an
interrupt storm.
Convert the driver to use a regular interrupt for the demultiplex
handler. This allows the interrupt storm detector to catch the malfunction
and lets the system boot up.
This should be backported to stable because it's likely that more users run
into this problem as the AMD Ryzen machines are spreading.

Something like this, I guess. But I need to find a box to test it.

Subject: [PATCH 1/4] ALSA: hda - A new flag to enforce prefix to each pin
This is a preliminary patch for a smooth multi-codec support, and it
introduces a new flag, force_pin_prefix, to struct hda_codec.
This flag is used to force to add the pin location prefix to each
input pin. For example, when there is only one microphone pin,
usually the auto-parser assigns the string "Mic". With this flag on,
it'll be like "Front Mic". Also, the creation of "Master" or "PCM"
playback volume for a single pin is suppressed, too.

Another preliminary patch for the dual-codec support: since the
support of vmaster over multiple codecs is difficult, simply disable
it by a new flag to hda_codec struct. A new user hint is added as
well for consistency.

Subject: [PATCH] ALSA: hda - Apply quirks to Broxton-T, too
Broxton-T was a forgotten child and we didn't apply the quirks for
Skylake+ properly. Meanwhile, a quirk for reducing the DMA latency
seems specific to the early Broxton model, so we leave as is.

Subject: [PATCH] ALSA: hda - Fix applying MSI dual-codec mobo quirk
The previous commit [63691587f7b0: ALSA: hda - Apply dual-codec quirk
for MSI Z270-Gaming mobo] attempted to apply the existing dual-codec
quirk for a MSI mobo. But it turned out that this isn't applied
properly due to the MSI-vendor quirk before this entry. I overlooked
such two MSI entries just because they were put in the wrong position,
although we have a list ordered by PCI SSID numbers.
This patch fixes it by rearranging the unordered entries.
Fixes: 63691587f7b0 ("ALSA: hda - Apply dual-codec quirk for MSI Z270-Gaming mobo")

Subject: [PATCH 3/4] ALSA: hda - Support Gigabyte Gaming board with dual
Realtek codecs
This patch adds some workarounds to make Gigabyte GA-AX370 Gaming 5
board working without the conflicts of kctls, etc. In general, the
dual codec configs result in the conflicts of the following stuff:
- Master controls
- Capture controls
- Analog loopback controls
In addition, the auto-mute and the auto-mic can't work well among
multiple codecs.
The current "solution" is to disable all these features, and use UCM
for a better PulseAudio management. For a dedicated UCM profile, the
patch overrides the card longname so that the system an get a unique
profile path.

Subject: af_unix: Add sockaddr length checks before accessing sa_family in bind and connect handlers
From: Mateusz Jurczyk <mjurczyk@google.com>
[ Upstream commit defbcf2decc903a28d8398aa477b6881e711e3ea ]
Verify that the caller-provided sockaddr structure is large enough to
contain the sa_family field, before accessing it in bind() and connect()
handlers of the AF_UNIX socket. Since neither syscall enforces a minimum
size of the corresponding memory region, very short sockaddrs (zero or
one byte long) result in operating on uninitialized memory while
referencing .sa_family.

Subject: decnet: always not take dst->__refcnt when inserting dst into hash table
From: Wei Wang <weiwan@google.com>
[ Upstream commit 76371d2e3ad1f84426a30ebcd8c3b9b98f4c724f ]
In the existing dn_route.c code, dn_route_output_slow() takes
dst->__refcnt before calling dn_insert_route() while dn_route_input_slow()
does not take dst->__refcnt before calling dn_insert_route().
This makes the whole routing code very buggy.
In dn_dst_check_expire(), dnrt_free() is called when rt expires. This
makes the routes inserted by dn_route_output_slow() not able to be
freed as the refcnt is not released.
In dn_dst_gc(), dnrt_drop() is called to release rt which could
potentially cause the dst->__refcnt to be dropped to -1.
In dn_run_flush(), dst_free() is called to release all the dst. Again,
it makes the dst inserted by dn_route_output_slow() not able to be
released and also, it does not wait on the rcu and could potentially
cause crash in the path where other users still refer to this dst.
This patch makes sure both input and output path do not take
dst->__refcnt before calling dn_insert_route() and also makes sure
dnrt_free()/dst_free() is called when removing dst from the hash table.
The only difference between those 2 calls is that dnrt_free() waits on
the rcu while dst_free() does not.

From: Mateusz Jurczyk <mjurczyk@google.com>
[ Upstream commit dd0da17b209ed91f39872766634ca967c170ada1 ]
Verify that the length of the socket buffer is sufficient to cover the
nlmsghdr structure before accessing the nlh->nlmsg_len field for further
input sanitization. If the client only supplies 1-3 bytes of data in
sk_buff, then nlh->nlmsg_len remains partially uninitialized and
contains leftover memory from the corresponding kernel allocation.
Operating on such data may result in indeterminate evaluation of the
nlmsg_len < sizeof(*nlh) expression.
The bug was discovered by a runtime instrumentation designed to detect
use of uninitialized memory in the kernel. The patch prevents this and
other similar tools (e.g. KMSAN) from flagging this behavior in the future.

Subject: drm: Fix broken VT switch with video=1366x768 option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From: Takashi Iwai <tiwai@suse.de>
commit fdf35a6b22247746a7053fc764d04218a9306f82 upstream.
I noticed that the VT switch doesn't work any longer with a Dell
laptop with 1366x768 eDP when the machine is connected with a DP
monitor. It behaves as if VT were switched, but the graphics remain
frozen. Actually the keyboard works, so I could switch back to VT7
again.
I tried to track down the problem, and encountered a long story until
we reach to this error:
- The machine is booted with video=1366x768 option (the distro
installer seems to add it as default).
- Recently, drm_helper_probe_single_connector_modes() deals with
cmdline modes, and it tries to create a new mode when no
matching mode is found.
- The drm_mode_create_from_cmdline_mode() creates a mode based on
either CVT of GFT according to the given cmdline mode; in our case,
it's 1366x768.
- Since both CVT and GFT can't express the width 1366 due to
alignment, the resultant mode becomes 1368x768, slightly larger than
the given size.
- Later on, the atomic commit is performed, and in
drm_atomic_check_only(), the size of each plane is checked.
- The size check of 1366x768 fails due to the above, and eventually
the whole VT switch fails.
Back in the history, we've had a manual fix-up of 1368x768 in various
places via c09dedb7a50e ("drm/edid: Add a workaround for 1366x768 HD
panel"), but they have been all in drm_edid.c at probing the modes
from EDID. For addressing the problem above, we need a similar hack
to the mode newly created from cmdline, manually adjusting the width
when the expected size is 1366 while we get 1368 instead.

commit 3bfdfdcbce2796ce75bf2d85fd8471858d702e5d upstream.
When the plane is invisible we may have all sorts of bogus stuff
in the coordinates, which we must ignore or else we might fail the
plane update. This started to happen on SKL when I moved the plane
offset computation to happen in the check phase. Previously we
happily ignored it all since we never called the update_plane hook
with an invisible plane.

Subject: drm: Schedule the output_poll_work with 1s delay if we have delayed event
From: Peter Ujfalusi <peter.ujfalusi@ti.com>
commit 68f458eec7069d618a6c884ca007426e0cea411b upstream.
Instead of scheduling the work to handle the initial delayed event, use 1s
delay.
This delay should not be needed, but Optimus/nouveau will fail in a
mysterious way if the delayed event is handled as soon as possible like it
is done in drm_helper_probe_single_connector_modes() in case the poll
was enabled before.
Reverting 339fd36238dd would give back the 10 sec (!) delay to handle the
delayed event. Adding 1sec delay to the poll_work is enough to work around
the issue in Optimus setups and gives shorter response on handling the
initial delayed event.

Subject: Fix an intermittent pr_emerg warning about lo becoming free.
From: Krister Johansen <kjlx@templeofstupid.com>
[ Upstream commit f186ce61bb8235d80068c390dc2aad7ca427a4c2 ]
It looks like this:
Message from syslogd@flamingo at Apr 26 00:45:00 ...
kernel:unregister_netdevice: waiting for lo to become free. Usage count = 4
They seem to coincide with net namespace teardown.
The message is emitted by netdev_wait_allrefs().
Forced a kdump in netdev_run_todo, but found that the refcount on the lo
device was already 0 at the time we got to the panic.
Used bcc to check the blocking in netdev_run_todo. The only places
where we're off cpu there are in the rcu_barrier() and msleep() calls.
That behavior is expected. The msleep time coincides with the amount of
time we spend waiting for the refcount to reach zero; the rcu_barrier()
wait times are not excessive.
After looking through the list of callbacks that the netdevice notifiers
invoke in this path, it appears that the dst_dev_event is the most
interesting. The dst_ifdown path places a hold on the loopback_dev as
part of releasing the dev associated with the original dst cache entry.
Most of our notifier callbacks are straight-forward, but this one a)
looks complex, and b) places a hold on the network interface in
question.
I constructed a new bcc script that watches various events in the
liftime of a dst cache entry. Note that dst_ifdown will take a hold on
the loopback device until the invalidated dst entry gets freed.

[ Upstream commit c38b7d327aafd1e3ad7ff53eefac990673b65667 ]
Andrey reported a use-after-free in add_grec():
for (psf = *psf_list; psf; psf = psf_next) {
...
psf_next = psf->sf_next;
where the struct ip_sf_list's were already freed by:
kfree+0xe8/0x2b0 mm/slub.c:3882
ip_mc_clear_src+0x69/0x1c0 net/ipv4/igmp.c:2078
ip_mc_dec_group+0x19a/0x470 net/ipv4/igmp.c:1618

sock_release+0x8d/0x1e0 net/socket.c:597
sock_close+0x16/0x20 net/socket.c:1072
This happens because we don't hold pmc->lock in ip_mc_clear_src()
and a parallel mr_ifc_timer timer could jump in and access them.
The RCU lock is there but it is merely for pmc itself, this
spinlock could actually ensure we don't access them in parallel.
Thanks to Eric and Long for discussion on this bug.

We miss a spin_lock_init() in igmpv3_add_delrec(), probably
because previously we never use it on this code path. Since
we already unlink it from the global mc_tomb list, it is
probably safe not to acquire this spinlock here. It does not
harm to have it although, to avoid conditional locking.

Subject: ipv6: Do not leak throw route references
From: Serhey Popovych <serhe.popovych@gmail.com>
[ Upstream commit 07f615574f8ac499875b21c1142f26308234a92c ]
While commit 73ba57bfae4a ("ipv6: fix backtracking for throw routes")
does good job on error propagation to the fib_rules_lookup()
in fib rules core framework that also corrects throw routes
handling, it does not solve route reference leakage problem
happened when we return -EAGAIN to the fib_rules_lookup()
and leave routing table entry referenced in arg->result.
If rule with matched throw route isn't last matched in the
list we overwrite arg->result losing reference on throw
route stored previously forever.
We also partially revert commit ab997ad40839 ("ipv6: fix the
incorrect return value of throw route") since we never return
routing table entry with dst.error == -EAGAIN when
CONFIG_IPV6_MULTIPLE_TABLES is on. Also there is no point
to check for RTF_REJECT flag since it is always set throw
route.

Subject: ipv6: fix calling in6_ifa_hold incorrectly for dad work
From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit f8a894b218138888542a5058d0e902378fd0d4ec ]
Now when starting the dad work in addrconf_mod_dad_work, if the dad work
is idle and queued, it needs to hold ifa.
The problem is there's one gap in [1], during which if the pending dad work
is removed elsewhere. It will miss to hold ifa, but the dad word is still
idea and queue.
if (!delayed_work_pending(&ifp->dad_work))
in6_ifa_hold(ifp);
<--------------[1]
mod_delayed_work(addrconf_wq, &ifp->dad_work, delay);
An use-after-free issue can be caused by this.
Chen Wei found this issue when WARN_ON(!hlist_unhashed(&ifp->addr_lst)) in
net6_ifa_finish_destroy was hit because of it.
As Hannes' suggestion, this patch is to fix it by holding ifa first in
addrconf_mod_dad_work, then calling mod_delayed_work and putting ifa if
the dad_work is already in queue.
Note that this patch did not choose to fix it with:
if (!mod_delayed_work(delay))
in6_ifa_hold(ifp);
As with it, when delay == 0, dad_work would be scheduled immediately, all
addrconf_mod_dad_work(0) callings had to be moved under ifp->lock.

Subject: net: 8021q: Fix one possible panic caused by BUG_ON in free_netdev
From: Gao Feng <gfree.wind@vip.163.com>
[ Upstream commit 9745e362add89432d2c951272a99b0a5fe4348a9 ]
The register_vlan_device would invoke free_netdev directly, when
register_vlan_dev failed. It would trigger the BUG_ON in free_netdev
if the dev was already registered. In this case, the netdev would be
freed in netdev_run_todo later.
So add one condition check now. Only when dev is not registered, then
free it directly.
The following is the part coredump when netdev_upper_dev_link failed
in register_vlan_dev. I removed the lines which are too long.

Subject: net: caif: Fix a sleep-in-atomic bug in cfpkt_create_pfx
From: Jia-Ju Bai <baijiaju1990@163.com>
[ Upstream commit f146e872eb12ebbe92d8e583b2637e0741440db3 ]
The kernel may sleep under a rcu read lock in cfpkt_create_pfx, and the
function call path is:
cfcnfg_linkup_rsp (acquire the lock by rcu_read_lock)
cfctrl_linkdown_req
cfpkt_create
cfpkt_create_pfx
alloc_skb(GFP_KERNEL) --> may sleep
cfserl_receive (acquire the lock by rcu_read_lock)
cfpkt_split
cfpkt_create_pfx
alloc_skb(GFP_KERNEL) --> may sleep
There is "in_interrupt" in cfpkt_create_pfx to decide use "GFP_KERNEL" or
"GFP_ATOMIC". In this situation, "GFP_KERNEL" is used because the function
is called under a rcu read lock, instead in interrupt.
To fix it, only "GFP_ATOMIC" is used in cfpkt_create_pfx.

From: Alexander Potapenko <glider@google.com>
[ Upstream commit c28294b941232931fbd714099798eb7aa7e865d7 ]
KMSAN reported a use of uninitialized memory in dev_set_alias(),

Subject: net/mlx5: Wait for FW readiness before initializing command interface
From: Eli Cohen <eli@mellanox.com>
[ Upstream commit 6c780a0267b8a1075f40b39851132eeaefefcff5 ]
Before attempting to initialize the command interface we must wait till
the fw_initializing bit is clear.
If we fail to meet this condition the hardware will drop our
configuration, specifically the descriptors page address. This scenario
can happen when the firmware is still executing an FLR flow and did not
finish yet so the driver needs to wait for that to finish.

Subject: net/mlx5e: Added BW check for DIM decision mechanism
From: Tal Gilboa <talgi@mellanox.com>
[ Upstream commit c3164d2fc48fd4fa0477ab658b644559c3fe9073 ]
DIM (Dynamically-tuned Interrupt Moderation) is a mechanism designed for
changing the channel interrupt moderation values in order to reduce CPU
overhead for all traffic types.
Until now only interrupt and packet rate were sampled.
We found a scenario on which we get a false indication since a change in
DIM caused more aggregation and reduced packet rate while increasing BW.
We now regard a change as succesfull iff:
current_BW > (prev_BW + threshold) or
current_BW ~= prev_BW and current_PR > (prev_PR + threshold) or
current_BW ~= prev_BW and current_PR ~= prev_PR and
current_IR < (prev_IR - threshold)
Where BW = Bandwidth, PR = Packet rate and IR = Interrupt rate
Improvements (ConnectX-4Lx 25GbE, single RX queue, LRO off)
--------------------------------------------------
packet size | before[Mb/s] | after[Mb/s] | gain |
2B | 343.4 | 359.4 | 4.5% |
16B | 2739.7 | 2814.8 | 2.7% |

Currently the VF reps don't register that callback and we crash

Subject: net/mlx5e: Fix wrong indications in DIM due to counter wraparound
From: Tal Gilboa <talgi@mellanox.com>
[ Upstream commit 53acd76ce571e3b71f9205f2d49ab285a9f1aad8 ]
DIM (Dynamically-tuned Interrupt Moderation) is a mechanism designed for
changing the channel interrupt moderation values in order to reduce CPU
overhead for all traffic types.
Each iteration of the algorithm, DIM calculates the difference in
throughput, packet rate and interrupt rate from last iteration in order
to make a decision. DIM relies on counters for each metric. When these
counters get to their type's max value they wraparound. In this case
the delta between 'end' and 'start' samples is negative and when
translated to unsigned integers - very high. This results in a false
indication to the algorithm and might result in a wrong decision.
The fix calculates the 'distance' between 'end' and 'start' samples in a
cyclic way around the relevant type's max value. It can also be viewed as
an absolute value around the type's max value instead of around 0.
Testing show higher stability in DIM profile selection and no wraparound
issues.

adds the l3mdev FIB rule the first time a VRF device is created. However,
it only creates the rule once and only in the namespace the first device
is created - which may not be init_net. Fix by using the net_generic

From: Christian Perle <christian.perle@secunet.com>
[ Upstream commit 3500cd73dff48f28f4ba80c171c4c80034d40f76 ]
Reading /proc/net/snmp6 yields bogus values on 32 bit kernels.
Use "u64" instead of "unsigned long" in sizeof().

Subject: sctp: disable BH in sctp_for_each_endpoint
From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit 581409dacc9176b0de1f6c4ca8d66e13aa8e1b29 ]
Now sctp holds read_lock when foreach sctp_ep_hashtable without disabling
BH. If CPU schedules to another thread A at this moment, the thread A may
be trying to hold the write_lock with disabling BH.
As BH is disabled and CPU cannot schedule back to the thread holding the
read_lock, while the thread A keeps waiting for the read_lock. A dead
lock would be triggered by this.
This patch is to fix this dead lock by calling read_lock_bh instead to
disable BH when holding the read_lock in sctp_for_each_endpoint.

Subject: sctp: return next obj by passing pos + 1 into sctp_transport_get_idx
From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit 988c7322116970696211e902b468aefec95b6ec4 ]
In sctp_for_each_transport, pos is used to save how many objs it has
dumped. Now it gets the last obj by sctp_transport_get_idx, then gets
the next obj by sctp_transport_get_next.
The issue is that in the meanwhile if some objs in transport hashtable
are removed and the objs nums are less than pos, sctp_transport_get_idx
would return NULL and hti.walker.tbl is NULL as well. At this moment
it should stop hti, instead of continue getting the next obj. Or it
would cause a NULL pointer dereference in sctp_transport_get_next.
This patch is to pass pos + 1 into sctp_transport_get_idx to get the
next obj directly, even if pos > objs nums, it would return NULL and
stop hti.

Subject: sfc: provide dummy definitions of vswitch functions
From: Bert Kenward <bkenward@solarflare.com>
efx_probe_all() calls efx->type->vswitching_probe during probe. For
SFC4000 (Falcon) NICs this function is not defined, leading to a BUG
with the top of the call stack similar to:
? efx_pci_probe_main+0x29a/0x830
efx_pci_probe+0x7d3/0xe70
vswitching_restore and vswitching_remove also need to be defined.
Fixed in mainline by:
commit 5a6681e22c14 ("sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driver")
Fixes: 6d8aaaf6f798 ("sfc: create VEB vswitch and vport above default firmware setup")

Subject: xhci: Limit USB2 port wake support for AMD Promontory hosts
For AMD Promontory xHCI host, although you can disable USB 2.0 ports in
BIOS settings, those ports will be enabled anyway after you remove a
device on that port and re-plug it in again. It's a known limitation of
the chip. As a workaround we can clear the PORT_WAKE_BITS.
This will disable wake on connect, disconnect and overcurrent on
AMD Promontory USB2 ports

===============================================================================
Phasing out MTRR use
-MTRR use is replaced on modern x86 hardware with PAT. Direct MTRR use by
-drivers on Linux is now completely phased out, device drivers should use
-arch_phys_wc_add() in combination with ioremap_wc() to make MTRR effective on
-non-PAT systems while a no-op but equally effective on PAT enabled systems.
-
-Even if Linux does not use MTRRs directly, some x86 platform firmware may still
-set up MTRRs early before booting the OS. They do this as some platform
-firmware may still have implemented access to MTRRs which would be controlled
-and handled by the platform firmware directly. An example of platform use of
-MTRRs is through the use of SMI handlers, one case could be for fan control,
-the platform code would need uncachable access to some of its fan control
-registers. Such platform access does not need any Operating System MTRR code in
-place other than mtrr_type_lookup() to ensure any OS specific mapping requests
-are aligned with platform MTRR setup. If MTRRs are only set up by the platform
-firmware code though and the OS does not make any specific MTRR mapping
-requests mtrr_type_lookup() should always return MTRR_TYPE_INVALID.
+MTRR use is replaced on modern x86 hardware with PAT. Over time the only type
+of effective MTRR that is expected to be supported will be for write-combining.
+As MTRR use is phased out device drivers should use arch_phys_wc_add() to make
+MTRR effective on non-PAT systems while a no-op on PAT enabled systems.
For details refer to Documentation/x86/pat.txt.

Subject: [PATCH] ACPICA: Events: Fix acpi_ev_initialize_region() return value
ACPICA commit 543342ab7a676f4eb0c9f100d349388a84dff0e8
This patch changes acpi_ev_initialize_region(), stop returning AE_NOT_EXIST
from it so that, not only in acpi_ds_load2_end_op(), but all places invoking
this function won't emit exceptions. The exception can be seen in
acpi_ds_initialize_objects() when certain table loading mode is chosen.
This patch also removes useless acpi_ns_locked from acpi_ev_initialize_region()
as this function will always be invoked with interpreter lock held now, and
the lock granularity has been tuned to lock around _REG execution, thus it
is now handled by acpi_ex_exit_interpreter(). Lv Zheng.

Subject: [PATCH] jbd2: Fix dbench4 performance regression for 'nobarrier' mounts
Date: Fri, 28 Apr 2017 11:59:34 +0200
Commit b685d3d65ac7 "block: treat REQ_FUA and REQ_PREFLUSH as
synchronous" removed REQ_SYNC flag from WRITE_FUA implementation. Since
JBD2 strips REQ_FUA and REQ_FLUSH flags from submitted IO when the
filesystem is mounted with nobarrier mount option, journal superblock
writes ended up being async writes after this patch and that caused
heavy performance regression for dbench4 benchmark with high number of
processes. In my test setup with HP RAID array with non-volatile write
cache and 32 GB ram, dbench4 runs with 8 processes regressed by ~25%.
Fix the problem by making sure journal superblock writes are always
treated as synchronous since they generally block progress of the
journalling machinery and thus the whole filesystem.
Fixes: b685d3d65ac791406e0dfd8779cc9b3707fea5a3
