Steven Rostedt 3ccb012392 tracing: Only run synchronize_sched() at instance deletion time
It has been reported that boot up with FTRACE_SELFTEST enabled can take a
very long time. There can be stalls of over a minute.

This was tracked down to the synchronize_sched() called when a system call
event is disabled. As the self tests enable and disable thousands of events,
this makes the synchronize_sched() get called thousands of times.

The synchornize_sched() was added with d562aff93b "tracing: Add support
for SOFT_DISABLE to syscall events" which caused this regression (added
in 3.13-rc1).

The synchronize_sched() is to protect against the events being accessed
when a tracer instance is being deleted. When an instance is being deleted
all the events associated to it are unregistered. The synchronize_sched()
makes sure that no more users are running when it finishes.

Instead of calling synchronize_sched() for all syscall events, we only
need to call it once, after the events are unregistered and before the
instance is deleted. The event_mutex is held during this action to
prevent new users from enabling events.

Pull x86 and EFI fixes from Peter Anvin:
 "Half of these are EFI-related:

  The by far biggest change is the change to hold off the deletion of a
  sysfs entry while a backend scan is in progress.  This is to avoid
  calling kmemdup() while under a spinlock.

  The other major change is for each entry in the EFI pstore backend to
  get a unique identifier, as required by the pstore filesystem proper.

  The other changes are:

  A fix to the recent consolidation and optimization of using "asm goto"
  with read-modify-write operation, which broke the bitops; specifically
  in such a way that we could end up generating invalid code.

  A build hack to make sure we compile with -mno-sse.  icc, and most
  likely future versions of gcc, can generate SSE instructions unless we
  tell it not to.

  A comment-only patch to a change the was due in part to an unpublished
  erratum; now when the erratum is published we want to add a comment
  explaining why"

Just flushing out my pile of bugfixes, most of them for regressions/cc:
stable. Nothing really serious going on.

For outstanding issues we still have the S4 fun due to the hsw S4
duct-tape pending (seems like I need to switch into angry maintainer mode
on that one). And there's the mode merging revert to make my g33 work
again still pending for drm core. For that one I don't have any more clue
(and it looks like no one else has a good idea either). And apparently the
locking WARN fix in here also needs to be replicated for boot, still
confirming that one though.

Comments:
In the latest version (4.7.3) of gcc compiler, it requres that
libraries must follow the object or source files like below:

"gcc hello.c -lpthread" instead of "gcc -lpthread hello.c"

And it isn't encountered at gcc version 4.7.2.

H. Peter Anvin e0f6dec35f x86, bitops: Correct the assembly constraints to testing bitops
In checkin:

0c44c2d0f4 x86: Use asm goto to implement better modify_and_test() functions

the various functions which do modify and test were unified and
optimized using "asm goto".  However, this change missed the detail
that the bitops require an "Ir" constraint rather than an "er"
constraint ("I" = integer constant from 0-31, "e" = signed 32-bit
integer constant).  This would cause code to miscompile if these
functions were used on constant bit positions 32-255 and the build to
fail if used on constant bit positions above 255.

Add the constraints as a parameter to the GEN_BINARY_RMWcc() macro to
avoid this problem.

Thomas Hellstrom 308d17ef95 drm/vmwgfx: Fix dma buffer memory size accounting
Also request kernel ttm_buffer objects for buffer objects that obviously
aren't visible to user-space, and save some device address space.

The accounting was broken in a couple of ways:
1) We did not differentiate between user dma buffers and kernel dma buffers.
2) The ttm_bo_acc_size function is broken in that it
a) Doesn't take into account the size of the optional dma address array,
b) Doesn't take into account the fact that drivers typically embed the
ttm_tt structure.

This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific
function to do the job.

Trond Myklebust f22e5edd22 NFSv4.1: Prevent a 3-way deadlock between layoutreturn, open and state recovery
Andy Adamson reports:

The state manager is recovering expired state and recovery OPENs are being
processed. If kswapd is pruning inodes at the same time, a deadlock can occur
when kswapd calls evict_inode on an NFSv4.1 inode with a layout, and the
resultant layoutreturn gets an error that the state mangager is to handle,
causing the layoutreturn to wait on the (NFS client) cl_rpcwaitq.

At the same time an open is waiting for the inode deletion to complete in
__wait_on_freeing_inode.

If the open is either the open called by the state manager, or an open from
the same open owner that is holding the NFSv4 sequence id which causes the
OPEN from the state manager to wait for the sequence id on the Seqid_waitqueue,
then the state is deadlocked with kswapd.

The fix is simply to have layoutreturn ignore all errors except NFS4ERR_DELAY.
We already know that layouts are dropped on all server reboots, and that
it has to be coded to deal with the "forgetful client model" that doesn't
send layoutreturns.

Another batch of fixes for ARM SoCs for 3.13. The diffstat is large,

 - Another set of fixes to fix regressions caused by moving OMAP from board
   files to DT. Tony thinks this was the last major set of fixes, with
   maybe just a few small patches to follow.
 - More fixes for Marvell platforms, most dealing with misdescribed PCIe
   hardware, i.e. incorrect number of busses on some SoCs, etc. The line
   delta adds up due to various ranges moving around when this is fixed.
 
 But there's also:
 
 - Some smaller tweaks to defconfigs to make more boards bootable in my
   test setup for better coverage.
 - There are also a few other smaller fixes, a short series for at91, a couple
   of reverts for ux500, etc.

Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Olof Johansson:
 "Another batch of fixes for ARM SoCs for 3.13.  The diffstat is large,
  mostly because of:

   - Another set of fixes to fix regressions caused by moving OMAP from
     board files to DT.  Tony thinks this was the last major set of
     fixes, with maybe just a few small patches to follow.
   - More fixes for Marvell platforms, most dealing with misdescribed
     PCIe hardware, i.e.  incorrect number of busses on some SoCs, etc.
     The line delta adds up due to various ranges moving around when
     this is fixed.

  But there's also:

   - Some smaller tweaks to defconfigs to make more boards bootable in
     my test setup for better coverage.
   - There are also a few other smaller fixes, a short series for at91,
     a couple of reverts for ux500, etc"

Linus Torvalds 8aa9c36788 Merge branch 'parisc-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parsic updates from Helge Deller:
 - a fix for the mmap(MAP_FIXED|MAP_SHARED) syscall to the same address
   which was already given in a previous call (fixes locale-gen on
   debian)
 - change the memory layout of the kernel to avoid the need for the
   -mlong-calls compiler option (depends on commit 5ecbe3c3c6 -
   "kernel/extable: fix address-checks for core_kernel and init areas")
 - defconfig updates, e.g.  use the SIL680 driver instead of the SIIMAGE
   driver
 - add more parisc machine names to the machine database

* 'parisc-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: update 64bit defconfigs and use SIL680 instead of SIIMAGE driver
  parisc: remove CONFIG_MLONGCALLS=y from defconfigs
  parisc: fix kernel memory layout in vmlinux.ld.S
  parisc: use kernel_text_address() in unwind functions
  parisc: remove empty SERIAL_PORT_DFNS in serial.h
