Pu Hou fc3100d64f s390/perf: fix bug when creating per-thread event
A per-thread event could not be created correctly like below:

    perf record --per-thread -e rB0000 -- sleep 1
    Error:
    The sys_perf_event_open() syscall returned with 19 (No such device) for event (rB0000).
    /bin/dmesg may provide additional information.
    No CONFIG_PERF_EVENTS=y kernel support configured?

This bug was introduced by:

    commit c311c79799
    Author: Alexey Dobriyan <adobriyan@gmail.com>
    Date:   Mon May 8 15:56:15 2017 -0700

    cpumask: make "nr_cpumask_bits" unsigned

If a per-thread event is not attached to any CPU, the cpu field
in struct perf_event is -1. The above commit converts the CPU number
to unsigned int, which result in an illegal CPU number.

Linus Torvalds 6d8ef53e8b for-f2fs-4.14
In this round, we've mostly tuned f2fs to provide better user experience
 for Android. Especially, we've worked on atomic write feature again with
 SQLite community in order to support it officially. And we added or modified
 several facilities to analyze and enhance IO behaviors.
 
 Major changes include:
 - add app/fs io stat
 - add inode checksum feature
 - support project/journalled quota
 - enhance atomic write with new ioctl() which exposes feature set
 - enhance background gc/discard/fstrim flows with new gc_urgent mode
 - add F2FS_IOC_FS{GET,SET}XATTR
 - fix some quota flows

Richard Wareing b31ff3cdf5 xfs: XFS_IS_REALTIME_INODE() should be false if no rt device present
If using a kernel with CONFIG_XFS_RT=y and we set the RHINHERIT flag on
a directory in a filesystem that does not have a realtime device and
create a new file in that directory, it gets marked as a real time file.
When data is written and a fsync is issued, the filesystem attempts to
flush a non-existent rt device during the fsync process.

This results in a crash dereferencing a null buftarg pointer in
xfs_blkdev_issue_flush():

  BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
  IP: xfs_blkdev_issue_flush+0xd/0x20
  .....
  Call Trace:
    xfs_file_fsync+0x188/0x1c0
    vfs_fsync_range+0x3b/0xa0
    do_fsync+0x3d/0x70
    SyS_fsync+0x10/0x20
    do_syscall_64+0x4d/0xb0
    entry_SYSCALL64_slow_path+0x25/0x25

Setting RT inode flags does not require special privileges so any
unprivileged user can cause this oops to occur.  To reproduce, confirm
kernel is compiled with CONFIG_XFS_RT=y and run:

  # mkfs.xfs -f /dev/pmem0
  # mount /dev/pmem0 /mnt/test
  # mkdir /mnt/test/foo
  # xfs_io -c 'chattr +t' /mnt/test/foo
  # xfs_io -f -c 'pwrite 0 5m' -c fsync /mnt/test/foo/bar

Or just run xfstests with MKFS_OPTIONS="-d rtinherit=1" and wait.

Kernels built with CONFIG_XFS_RT=n are not exposed to this bug.

Besides, this patch also fixes to issue discards accurately with assigned

Daeho Jeong 0abd8e70d2 f2fs: clear radix tree dirty tag of pages whose dirty flag is cleared
On a senario like writing out the first dirty page of the inode
as the inline data, we only cleared dirty flags of the pages, but
didn't clear the dirty tags of those pages in the radix tree.

If we don't clear the dirty tags of the pages in the radix tree, the
inodes which contain the pages will be marked with I_DIRTY_PAGES again
and again, and writepages() for the inodes will be invoked in every
writeback period. As a result, nothing will be done in every
writepages() for the inodes and it will just consume CPU time
meaninglessly.

Linus Torvalds dd198ce714 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
 "Life has been busy and I have not gotten half as much done this round
  as I would have liked. I delayed it so that a minor conflict
  resolution with the mips tree could spend a little time in linux-next
  before I sent this pull request.

  This includes two long delayed user namespace changes from Kirill
  Tkhai. It also includes a very useful change from Serge Hallyn that
  allows the security capability attribute to be used inside of user
  namespaces. The practical effect of this is people can now untar
  tarballs and install rpms in user namespaces. It had been suggested to
  generalize this and encode some of the namespace information
  information in the xattr name. Upon close inspection that makes the
  things that should be hard easy and the things that should be easy
  more expensive.

  Then there is my bugfix/cleanup for signal injection that removes the
  magic encoding of the siginfo union member from the kernel internal
  si_code. The mips folks reported the case where I had used FPE_FIXME
  me is impossible so I have remove FPE_FIXME from mips, while at the
  same time including a return statement in that case to keep gcc from
  complaining about unitialized variables.

  I almost finished the work to get make copy_siginfo_to_user a trivial
  copy to user. The code is available at:

     git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3

  But I did not have time/energy to get the code posted and reviewed
  before the merge window opened.

  I was able to see that the security excuse for just copying fields
  that we know are initialized doesn't work in practice there are buggy
  initializations that don't initialize the proper fields in siginfo. So
  we still sometimes copy unitialized data to userspace"

resume event, and at least the btusb driver that uses a workqueue to
load the firmware at resume seems to occasionally hit the "firmware
loading is disabled" logic because the firmware loader hasn't gotten the
resume event yet.

Some kind of sanity check for not trying to load firmware when it's not
possible might be a good thing, but this commit was not it.

Greg seems to have silently suffered the same issue, and pointed to the
likely culprit, and Gabriel C verified the revert fixed it for him too.

Geert Uytterhoeven 4c2b5e0fab m68k: Add braces to __pmd(x) initializer to kill compiler warning
With gcc 4.1.2:

    include/linux/swapops.h: In function ‘swp_entry_to_pmd’:
    include/linux/swapops.h:294: warning: missing braces around initializer
    include/linux/swapops.h:294: warning: (near initialization for ‘(anonymous).pmd’)

Due to a GCC zero initializer bug (#53119), the standard "(pmd_t){ 0 }"
initializer is not accepted by all GCC versions.
In addition, on m68k pmd_t is an array instead of a single value, so we
need "(pmd_t){ { 0 }, }" instead of "(pmd_t){ 0 }".

Based on commit 9157259d16 ("mm: add pmd_t initializer __pmd() to
work around a GCC bug.") for sparc32.

Rob Gardner b6fe108966 sparc64: Handle additional cases of no fault loads
Load instructions using ASI_PNF or other no-fault ASIs should not
cause a SIGSEGV or SIGBUS.

A garden variety unmapped address follows the TSB miss path, and when
no valid mapping is found in the process page tables, the miss handler
checks to see if the access was via a no-fault ASI.  It then fixes up
the target register with a zero, and skips the no-fault load
instruction.

But different paths are taken for data access exceptions and alignment
traps, and these do not respect the no-fault ASI. We add checks in
these paths for the no-fault ASI, and fix up the target register and
TPC just like in the TSB miss case.

For many sun4v processor types, reading or writing a privileged register
has a latency of 40 to 70 cycles.  Use a combination of the low-latency
allclean, otherw, normalw, and nop instructions in etrap and rtrap to
replace 2 rdpr and 5 wrpr instructions and improve etrap/rtrap
performance.  allclean, otherw, and normalw are available on NG2 and
later processors.

Linus Torvalds 4dfc278803 IOMMU Updates for Linux v4.14
Slightly more changes than usual this time:
 
 	- KDump Kernel IOMMU take-over code for AMD IOMMU. The code now
 	  tries to preserve the mappings of the kernel so that master
 	  aborts for devices are avoided. Master aborts cause some
 	  devices to fail in the kdump kernel, so this code makes the
 	  dump more likely to succeed when AMD IOMMU is enabled.
 
 	- Common flush queue implementation for IOVA code users. The
 	  code is still optional, but AMD and Intel IOMMU drivers had
 	  their own implementation which is now unified.
 
 	- Finish support for iommu-groups. All drivers implement this
 	  feature now so that IOMMU core code can rely on it.
 
 	- Finish support for 'struct iommu_device' in iommu drivers. All
 	  drivers now use the interface.
 
 	- New functions in the IOMMU-API for explicit IO/TLB flushing.
 	  This will help to reduce the number of IO/TLB flushes when
 	  IOMMU drivers support this interface.
 
 	- Support for mt2712 in the Mediatek IOMMU driver
 
 	- New IOMMU driver for QCOM hardware
 
 	- System PM support for ARM-SMMU
 
 	- Shutdown method for ARM-SMMU-v3
 
 	- Some constification patches
 
 	- Various other small improvements and fixes

Merge tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU updates from Joerg Roedel:
 "Slightly more changes than usual this time:

   - KDump Kernel IOMMU take-over code for AMD IOMMU. The code now tries
     to preserve the mappings of the kernel so that master aborts for
     devices are avoided. Master aborts cause some devices to fail in
     the kdump kernel, so this code makes the dump more likely to
     succeed when AMD IOMMU is enabled.

   - common flush queue implementation for IOVA code users. The code is
     still optional, but AMD and Intel IOMMU drivers had their own
     implementation which is now unified.

   - finish support for iommu-groups. All drivers implement this feature
     now so that IOMMU core code can rely on it.

   - finish support for 'struct iommu_device' in iommu drivers. All
     drivers now use the interface.

   - new functions in the IOMMU-API for explicit IO/TLB flushing. This
     will help to reduce the number of IO/TLB flushes when IOMMU drivers
     support this interface.

   - support for mt2712 in the Mediatek IOMMU driver

   - new IOMMU driver for QCOM hardware

   - system PM support for ARM-SMMU

   - shutdown method for ARM-SMMU-v3

   - some constification patches

   - various other small improvements and fixes"

Trond Myklebust 1bd5d6d08e NFS: Count the bytes of skipped subrequests in nfs_lock_and_join_requests()
If we skip a subrequest due to a zero refcount, we should still count
the byte range that it covered so that we accurately reconstruct the
original request size.

Linus Torvalds 66ba772ee3 Merge branch 'for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
 "The changes range through all types: cleanups, core chagnes, sanity
  checks, fixes, other user visible changes, detailed list below:

   - deprecated: user transaction ioctl

   - mount option ssd does not change allocation alignments

   - degraded read-write mount is allowed if all the raid profile
     constraints are met, now based on more accurate check

   - defrag: do not reset compression afterwards; the NOCOMPRESS flag
     can be now overriden by defrag

   - prep work for better extent reference tracking (related to the
     qgroup slowness with balance)

   - prep work for compression heuristics

   - memory allocation reductions (may help latencies on a loaded
     system)

   - better accounting for io waiting states

   - error handling improvements (removed BUGs)

   - added more sanity checks for shared refs

   - fix readdir vs pagefault deadlock under some circumstances

   - fix for 'no-hole' mode, certain combination of compressed and
     inline extents

   - send: fix emission of invalid clone operations

   - fixup file mode if setting acls fail

   - more fixes from fuzzing

   - oher cleanups"
