The newly added SMB2+ attribute support causes unused function
warnings when CONFIG_CIFS_XATTR is disabled:

fs/cifs/smb2ops.c:563:1: error: 'smb2_set_ea' defined but not used [-Werror=unused-function]
 smb2_set_ea(const unsigned int xid, struct cifs_tcon *tcon,

This adds another #ifdef around the affected functions.

With the need to discourage use of less secure dialect, SMB1 (CIFS),
we temporarily upgraded the dialect to SMB3 in 4.13, but since there
are various servers which only support SMB2.1 (2.1 is more secure
than CIFS/SMB1) but not optimal for a default dialect - add support
for multidialect negotiation.  cifs.ko will now request SMB2.1
or later (ie SMB2.1 or SMB3.0, SMB3.02) and the server will
pick the latest most secure one it can support.

In addition since we are sending multidialect negotiate, add
support for secure negotiate to validate that a man in the
middle didn't downgrade us.

In SMB2_open there are several paths where the SendReceive2
call will return an error before it sets rsp_iov.iov_base
thus leaving iov_base uninitialized.

Thus we need to check rsp before we dereference it in
the call to get_rfc1002_length().

http://www.spinics.net/lists/linux-cifs/msg12846.html

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"

This reverts commit 81f95076.

It causes random failures of firmware loading at resume time (well,
random for me, it seems to be more reliable for others) because the
firmware disabling is not actually synchronous with any particular
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.

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 9157259d ("mm: add pmd_t initializer __pmd() to
work around a GCC bug.") for sparc32.

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.

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
