e6d0e1dcf5 mm/slub.c: wrap kmem_cache->cpu_partial in config CONFIG_SLUB_CPU_PARTIAL
kmem_cache->cpu_partial is just used when CONFIG_SLUB_CPU_PARTIAL is
set, so wrap it with config CONFIG_SLUB_CPU_PARTIAL will save some space
on 32bit arch.

This patch wraps kmem_cache->cpu_partial in config CONFIG_SLUB_CPU_PARTIAL
and wraps its sysfs too.

a93cf07bc3 mm/slub.c: wrap cpu_slab->partial in CONFIG_SLUB_CPU_PARTIAL
cpu_slab's field partial is used when CONFIG_SLUB_CPU_PARTIAL is set,
which means we can save a pointer's space on each cpu for every slub
item.

This patch wraps cpu_slab->partial in CONFIG_SLUB_CPU_PARTIAL and wraps
its sysfs use too.

d3111e6cce mm/slub.c: pack red_left_pad with another int to save a word
Patch series "try to save some memory for kmem_cache in some cases", v2.

kmem_cache is a frequently used data in kernel.  During the code
reading, I found maybe we could save some space in some cases.

1. On 64bit arch, type int will occupy a word if it doesn't sit well.

2. cpu_slab->partial is just used when CONFIG_SLUB_CPU_PARTIAL is set

3. cpu_partial is just used when CONFIG_SLUB_CPU_PARTIAL is set, while
   just save some space on 32bit arch.

This patch (of 3):

On 64bit arch, struct is 8-bytes aligned, so int will occupy a word if
it doesn't sit well.

This patch pack red_left_pad with reserved to save 8 bytes for struct
kmem_cache on a 64bit arch.

66fdbe5203 mm/slub.c: remove a redundant assignment in ___slab_alloc()
When the code comes to this point, there are two cases:
1. cpu_slab is deactivated
2. cpu_slab is empty

In both cased, cpu_slab->freelist is NULL at this moment.

This patch removes the redundant assignment of cpu_slab->freelist.

b74271e40e ocfs2: constify attribute_group structures
attribute_groups are not supposed to change at runtime.  All functions

   4402	   1088	     38	   5528	   1598	fs/ocfs2/stackglue.o

File size After adding 'const':

938f846492 provide linux/set_memory.h
Currently code that wants to use set_memory_ro() etc, needs to include
asm/set_memory.h, which doesn't exist on all arches.  Some code knows it
only builds on arches which have the header, other code guards the
inclusion with an #ifdef, neither is ideal.

So create linux/set_memory.h.  This always exists, so users don't need
an #ifdef just to include the header.

When CONFIG_ARCH_HAS_SET_MEMORY=y it includes asm/set_memory.h,
otherwise it provides empty non-failing implementations.

I have designs to use them in scatterlist.c where they'd likely never be

the function is ever hit it returns NULL.

it, put_page() would attempt to free the page before unlocking it.

The fix is trivial reorder of operations.

9a04dbcfb3 compiler, clang: always inline when CONFIG_OPTIMIZE_INLINING is disabled
The motivation for commit abb2ea7dfd ("compiler, clang: suppress
warning for unused static inline functions") was to suppress clang's
warnings about unused static inline functions.

For configs without CONFIG_OPTIMIZE_INLINING enabled, such as any non-x86
architecture, `inline' in the kernel implies that
__attribute__((always_inline)) is used.

Some code depends on that behavior, see
  https://lkml.org/lkml/2017/6/13/918:

  net/built-in.o: In function `__xchg_mb':
  arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99'
  arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99

The full fix would be to identify these breakages and annotate the
functions with __always_inline instead of `inline'.  But since we are
late in the 4.12-rc cycle, simply carry forward the forced inlining
behavior and work toward moving arm64, and other architectures, toward
CONFIG_OPTIMIZE_INLINING behavior.

c80081b920 genirq: Allow to pass the IRQF_TIMER flag with percpu irq request
The irq timings infrastructure tracks when interrupts occur in order to
statistically predict te next interrupt event.

There is no point to track timer interrupts and try to predict them because
the next expiration time is already known. This can be avoided via the
IRQF_TIMER flag which is passed by timer drivers in request_irq(). It marks
the interrupt as timer based which alloes to ignore these interrupts in the
timings code.

Per CPU interrupts which are requested via request_percpu_+irq() have no
flag argument, so marking per cpu timer interrupts is not possible and they
get tracked pointlessly.

Add __request_percpu_irq() as a variant of request_percpu_irq() with a
flags argument and make request_percpu_irq() an inline wrapper passing
flags = 0.

The flag parameter is restricted to IRQF_TIMER as all other IRQF_ flags
make no sense for per cpu interrupts.

The next step is to convert all existing users of request_percpu_irq() and
then remove the wrapper and the underscores.

Pull rdma update from Doug Ledford:
 "This includes two bugs against the newly added opa vnic that were
  found by turning on the debug kernel options:

   - sleeping while holding a lock, so a one line fix where they
     switched it from GFP_KERNEL allocation to a GFP_ATOMIC allocation

   - a case where they had an isolated caller of their code that could
     call them in an atomic context so they had to switch their use of a
     mutex to a spinlock to be safe, so this was considerably more lines
     of diff because all uses of that lock had to be switched

  In addition, the bug that was discussed with you already about an out
  of bounds array access in ib_uverbs_modify_qp and ib_uverbs_create_ah
  and is only seven lines of diff.

  And finally, one fix to an earlier fix in the -rc cycle that broke
  hfi1 and qib in regards to IPoIB (this one is, unfortunately, larger
  than I would like for a -rc7 submission, but fixing the problem
  required that we not treat all devices as though they had allocated a
  netdev universally because it isn't true, and it took 70 lines of diff
  to resolve the issue, but the final patch has been vetted by Intel and
  Mellanox and they've both given their approval to the fix).

  Summary:

   - Two fixes for OPA found by debug kernel
   - Fix for user supplied input causing kernel problems
   - Fix for the IPoIB fixes submitted around -rc4"

[ Doug sent this having not noticed the 4.12 release, so I guess I'll be
  getting another rdma pull request with the actuakl merge window
  updates and not just fixes.

  Oh well - it would have been nice if this small update had been the

ac7b75966c This is the big bulk of pin control changes for the v4.13 series:
Core:
 
 - The documentation is moved over to RST.
 - We now have agreed bindings for enabling input and output
   buffers without actually enabling input and/or output on a
   pin. We are chiseling out some details of pin control
   electronics.
 
 New drivers:
 
 - ZTE ZX
 - Renesas RZA1
 - MIPS Ingenic JZ47xx: also switch over existing drivers in the
   tree to use this pin controller and consolidate earlier
   spread out code.
 - Microschip MCP23S08: this driver is migrated from the GPIO
   subsystem and totally rewritten to use proper pin control.
   All users are switched over.
 
 New subdrivers:
 
 - Renesas R8A7743 and R8A7745.
 - Allwinner Sunxi A83T R_PIO.
 - Marvell MVEBU Armada CP110 and AP806.
 - Intel Cannon Lake PCH.
 - Qualcomm IPQ8074.
 
 Notable improvements:
 
 - IRQ support on the Marvell MVEBU Armada 37xx.
 - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
 - Rockchip driver now supports iomux-route switching for
   RK3228, RK3328 and RK3399.
 - Rockchip A10 and A20 are merged into a single driver.
 - STM32 has improved GPIO support.
 - Samsung Exynos drivers are split per ARMv7 and ARMv8.
 - Marvell MVEBU is converted to use regmap for register
   access.
 
 Maintenance:
 
 - Several Renesas SH-PFC refactorings and updates.
 - Serious code size cut for Mediatek MT7623.
 - Misc janitorial and MAINTAINERS fixes.

The changes in "block: Make most scsi_req_init() calls implicit" mean
that every driver that supports the generic scsi ioctls needs to
call scsi_req_init on newly allocated requests, but that commit didn't
add the call to the ccіss driver.  Fix that to avoid crashes when

920f2ecdf6 sound updates for 4.13-rc1
This development cycle resulted in a fair amount of changes in both
 core and driver sides.  The most significant change in ALSA core is
 about PCM.  Also the support of of-graph card and the new DAPM widget
 for DSP are noteworthy changes in ASoC core.  And there're lots of
 small changes splat over the tree, as you can see in diffstat.
 
 Below are a few highlights:
 
 ALSA core:
 - Removal of set_fs() hackery from PCM core stuff, and the code
   reorganization / optimization thereafter
 - Improved support of PCM ack ops, and a new ABI for improved
   control/status mmap handling
 - Lots of constifications in various codes
 
 ASoC core:
 - The support of of-graph card, which may work as a better generic
   device for a replacement of simple-card
 - New widget types intended mainly for use with DSPs
 
 ASoC drivers:
 - New drivers for Allwinner V3s SoCs
 - Ensonic ES8316 codec support
 - More Intel SKL and KBL works
 - More device support for Intel SST Atom (mostly for cheap tablets and
   2-in-1 devices)
 - Support for Rockchip PDM controllers
 - Support for STM32 I2S and S/PDIF controllers
 - Support for ZTE AUD96P22 codecs
 
 HD-audio:
 - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
   for HP and Dell machines
 - A few more fixes for i915 component binding
 
 Note that of-graph change may bring the conflicts with a later pull
 request of devicetree, as currently found in linux-next.

Merge tag 'sound-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "This development cycle resulted in a fair amount of changes in both
  core and driver sides. The most significant change in ALSA core is
  about PCM. Also the support of of-graph card and the new DAPM widget
  for DSP are noteworthy changes in ASoC core. And there're lots of
  small changes splat over the tree, as you can see in diffstat.

  Below are a few highlights:

  ALSA core:
   - Removal of set_fs() hackery from PCM core stuff, and the code
     reorganization / optimization thereafter
   - Improved support of PCM ack ops, and a new ABI for improved
     control/status mmap handling
   - Lots of constifications in various codes

  ASoC core:
   - The support of of-graph card, which may work as a better generic
     device for a replacement of simple-card
   - New widget types intended mainly for use with DSPs

  ASoC drivers:
   - New drivers for Allwinner V3s SoCs
   - Ensonic ES8316 codec support
   - More Intel SKL and KBL works
   - More device support for Intel SST Atom (mostly for cheap tablets
     and 2-in-1 devices)
   - Support for Rockchip PDM controllers
   - Support for STM32 I2S and S/PDIF controllers
   - Support for ZTE AUD96P22 codecs

  HD-audio:
   - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
     for HP and Dell machines
   - A few more fixes for i915 component binding"

f630c38ef0 vrf: fix bug_on triggered by rx when destroying a vrf
When destroying a VRF device we cleanup the slaves in its ndo_uninit()
function, but that causes packets to be switched (skb->dev == vrf being
destroyed) even though we're pass the point where the VRF should be
receiving any packets while it is being dismantled. This causes a BUG_ON
to trigger if we have raw sockets (trace below).
The reason is that the inetdev of the VRF has been destroyed but we're
still sending packets up the stack with it, so let's free the slaves in
the dellink callback as David Ahern suggested.

Note that this fix doesn't prevent packets from going up when the VRF
device is admin down.

615d22a51c block: Fix __blkdev_issue_zeroout loop
The BIO issuing loop in __blkdev_issue_zeroout() is allocating BIOs
with a maximum number of bvec (pages) equal to

min(nr_sects, (sector_t)BIO_MAX_PAGES)

This works since the requested number of bvecs will always be limited
to the absolute maximum number supported (BIO_MAX_PAGES), but this is
ineficient as too many bvec entries may be requested due to the
different units being used in the min() operation (number of sectors vs
number of pages).
To fix this, introduce the helper __blkdev_sectors_to_bio_pages() to
correctly calculate the number of bvecs for zeroout BIOs as the issuing
loop progresses. The calculation is done using consistent units and
makes sure that the number of pages return is at least 1 (for cases
where the number of sectors is less that the number of sectors in
a page).

Also remove a trailing space after the bit shift in the internal loop
min() call.
