The m68k arch doesn't have a kvm_para.h (unlike most or maybe all other
arches), but there is one in asm-generic.  This means that:

	ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \
			  $(srctree)/include/asm-$(SRCARCH)/kvm_para.h \
			  $(INSTALL_HDR_PATH)/include/asm-*/kvm_para.h),)
	header-y += kvm_para.h
	endif

gets it wrong because it is invoked twice during the header installation - and
on the second occasion, asm-generic/kvm_para.h has been installed in usr/,
thus triggering a attempt to install asm-m68k/kvm_para.h which will fail.

There are three headers with this sort of conditional logic: a.out.h, kvm.h
and kvm_para.h.  For all three of them, change the logic to be something like:

	ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \
			  $(srctree)/arch/$(SRCARCH)/include/uapi/asm/kvm_para.h),)

which finds the header in only the two places it should be found, and doesn't
get incorrectly triggered by the installation of asm-generic's version.

Avoid later problems with c6x's asm/signal.h lacking __KERNEL__ guards.
Signed-off-by: David Howells <dhowells@redhat.com>

The c6x signal.h includes the asm-generic version and provides
a couple of extern declarations. David Howells pointed out that
the externs needed to be protected by ifdef __KERNEL__. As it
turns out, the externs aren't really needed since the functions
are only called from asm code. So this patch gets rid of the
c6x signal.h and uses just the asm-generic version.

asm-generic/unistd.h and a number of asm/unistd.h files have been given
reinclusion guards that allow the guard to be overridden if __SYSCALL is
defined.  Unfortunately, these files define __SYSCALL and don't undefine it
when they've finished with it, thus rendering the guard ineffective.

The reason for this override is to allow the file to be #included multiple
times with different settings on __SYSCALL for purposes like generating syscall
tables.

The following guards are problematic:

arch/arm64/include/asm/unistd.h:#if !defined(__ASM_UNISTD_H) || defined(__SYSCALL)
arch/arm64/include/asm/unistd32.h:#if !defined(__ASM_UNISTD32_H) || defined(__SYSCALL)
arch/c6x/include/asm/unistd.h:#if !defined(_ASM_C6X_UNISTD_H) || defined(__SYSCALL)
arch/hexagon/include/asm/unistd.h:#if !defined(_ASM_HEXAGON_UNISTD_H) || defined(__SYSCALL)
arch/openrisc/include/asm/unistd.h:#if !defined(__ASM_OPENRISC_UNISTD_H) || defined(__SYSCALL)
arch/score/include/asm/unistd.h:#if !defined(_ASM_SCORE_UNISTD_H) || defined(__SYSCALL)
arch/tile/include/asm/unistd.h:#if !defined(_ASM_TILE_UNISTD_H) || defined(__SYSCALL)

include/asm-generic/unistd.h:#if !defined(_ASM_GENERIC_UNISTD_H) || defined(__SYSCALL)

On the assumption that the guards' ineffectiveness has passed unnoticed, just
remove these guards entirely.

Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's

  userns: Fix build of drivers/staging/dgrp

This is a first step in allowing people to by-pass udev for loading
device firmware.  Current versions of udev will deadlock (causing us to
block for the 30 second timeout) under some circumstances if the
firmware is loaded as part of the module initialization path, and this
is causing problems for media drivers in particular.

The current patch hardcodes the firmware path that udev uses by default,
and will fall back to the legacy udev mode if the firmware cannot be
found there.  We'd like to add support for both configuring the paths
and the fallback behaviour, but in the meantime this hopefully fixes the
immediate problem, while also giving us a way forward.

Pull preparatory patches for user API disintegration from David Howells:
 "The patches herein prepare for the extraction of the Userspace API
  bits from the various header files named in the Kbuild files.

  New subdirectories are created under either include/uapi/ or

  that file under include/ or arch/x/include/.

  The new subdirs under the uapi/ directory are populated with Kbuild
  files that mostly do nothing at this time.  Further patches will
  disintegrate the headers in each original directory and fill in the
  Kbuild files as they do it.

  These patches also:

   (1) fix up #inclusions of "foo.h" rather than <foo.h>.

   (2) Remove some redundant #includes from the DRM code.

   (3) Make the kernel build infrastructure handle Kbuild files both in
       the old places and the new UAPI place that both specify headers
       to be exported.

   (4) Fix some kernel tools that #include kernel headers during their
       build.

  allmodconfig against i386 and a scattering of additional defconfigs of

There's no caller of pcibios_assign_resources() in the tree.  It is
exported, so an out-of-tree module *could* call it, but no other arch
exports pcibios_assign_resources(), so it would have to be a CRIS-specific
module.  I doubt such a caller exists.

Pull vfs update from Al Viro:

 - big one - consolidation of descriptor-related logics; almost all of
   that is moved to fs/file.c

   (BTW, I'm seriously tempted to rename the result to fd.c.  As it is,
   we have a situation when file_table.c is about handling of struct
   file and file.c is about handling of descriptor tables; the reasons
   are historical - file_table.c used to be about a static array of
   struct file we used to have way back).

   A lot of stray ends got cleaned up and converted to saner primitives,
   disgusting mess in android/binder.c is still disgusting, but at least
   doesn't poke so much in descriptor table guts anymore.  A bunch of
   relatively minor races got fixed in process, plus an ext4 struct file
   leak.

 - related thing - fget_light() partially unuglified; see fdget() in
   there (and yes, it generates the code as good as we used to have).

 - also related - bits of Cyrill's procfs stuff that got entangled into
   that work; _not_ all of it, just the initial move to fs/proc/fd.c and
   switch of fdinfo to seq_file.

 - Alex's fs/coredump.c spiltoff - the same story, had been easier to
   take that commit than mess with conflicts.  The rest is a separate
   pile, this was just a mechanical code movement.

 - a few misc patches all over the place.  Not all for this cycle,
   there'll be more (and quite a few currently sit in akpm's tree)."

simple conflicts due to two different changes to the sock_alloc_file()
interface ("take descriptor handling from sock_alloc_file() to callers"
vs "net: Providing protocol type via system.sockprotoname xattr of
/proc/PID/fd entries" adding a dentry name to the socket)

prom_printf() takes printf style arguments.  Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().

This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

Hopefully fixed the tlb flush timeout issue.  Was able to observe this
condition occur occasionally, and it appears the binary driver doesn't
wait on the old condition either..

Should give 39-bit DMA addressing on the relevant chipsets.

Something seems to be missing in regards to flushing specific ranges of
the TLB.  For the moment, flushing the entire thing seems to make it
work alright.

Should give 39-bit DMA addressing on the relevant chipsets.

We don't need to pull the page address out of the page tables on nv4x
chips that have a real GART.

For now, only 2 control modes are available:
- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)

This patch introduces a distinction between ptherm internal fan management
and external fan management. The latter is bound to respect the fan mode
while the first can still select the speed it wants unless the NONE mode
is selected. This is important for automatic fan management.

The previous driver waited for 250ms to accumulate data. This version times a
complete fan rotation and extrapolates to RPM.

The fan rotational speed should now be read in less than 250ms (worst case)
and usually in less 50ms.
