Pull UAPI disintegration fixes from David Howells:
"There are three main parts:
(1) I found I needed some more fixups in the wake of testing Arm64
(some asm/unistd.h files had weird guards that caused problems -
mostly in arches for which I don't have a compiler) and some
__KERNEL__ splitting needed to take place in Arm64.
(2) I found that c6x was missing some __KERNEL__ guards in its
asm/signal.h. Mark Salter pointed me at a tree with a patch to
remove that file entirely and use the asm-generic variant instead.
(3) Lastly, m68k turned out to have a header installation problem due
to it lacking a kvm_para.h file.
The conditional installation bits for linux/kvm_para.h, linux/kvm.h
and linux/a.out.h weren't very well specified - and didn't work if
an arch didn't have the asm/ version of that file, but there *was*
an asm-generic/ version.
It seems the "ifneq $((wildcard ...),)" for each of those three
headers in include/kernel/Kbuild is invoked twice during header
installation, and the second time it matches on the just installed
asm-generic/kvm_para.h file and thus incorrectly installs
linux/kvm_para.h as well.
Most arches actually have an asm/kvm_para.h, so this wasn't
detectable in those."
* 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers:
UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k)
c6x: remove c6x signal.h
UAPI: Split compound conditionals containing __KERNEL__ in Arm64
UAPI: Fix the guards on various asm/unistd.h files
c6x: make dsk6455 the default config
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)

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.

"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

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.

is that the header files will be split or moved one at a time, but each header

simultaneously.

ARM recently moved to asm-generic/mutex-xchg.h for its mutex
implementation after the previous implementation was found to be missing
some crucial memory barriers. However, this has revealed some problems
running hackbench on SMP platforms due to the way in which the
MUTEX_SPIN_ON_OWNER code operates.
The symptoms are that a bunch of hackbench tasks are left waiting on an
unlocked mutex and therefore never get woken up to claim it. This boils
down to the following sequence of events:
Task A Task B Task C Lock value
0 1
1 lock() 0
2 lock() 0
3 spin(A) 0
4 unlock() 1
5 lock() 0
6 cmpxchg(1,0) 0
7 contended() -1
8 lock() 0
9 spin(C) 0
10 unlock() 1
11 cmpxchg(1,0) 0
12 unlock() 1
At this point, the lock is unlocked, but Task B is in an uninterruptible
sleep with nobody to wake it up.
This patch fixes the problem by ensuring we put the lock into the
contended state if we fail to acquire it on the fastpath, ensuring that
any blocked waiters are woken up when the mutex is released.

scatterlist: add sg_alloc_table_from_pages function
This patch adds dma_get_sgtable() function which is required to let
drivers to share the buffers allocated by DMA-mapping subsystem. Right
now the driver gets a dma address of the allocated buffer and the kernel
virtual mapping for it. If it wants to share it with other device (= map
into its dma address space) it usually hacks around kernel virtual
addresses to get pointers to pages or assumes that both devices share
the DMA address space. Both solutions are just hacks for the special
cases, which should be avoided in the final version of buffer sharing.
To solve this issue in a generic way, a new call to DMA mapping has been
introduced - dma_get_sgtable(). It allocates a scatter-list which
describes the allocated buffer and lets the driver(s) to use it with
other device(s) by calling dma_map_sg() on it.
This patch provides a generic implementation based on virt_to_page()
call. Architectures which require more sophisticated translation might
provide their own get_sgtable() methods.

This patch enabled the tlb flush range support in generic mmu layer.
Most of arch has self tlb flush range support, like ARM/IA64 etc.
X86 arch has no this support in hardware yet. But another instruction
'invlpg' can implement this function in some degree. So, enable this
feather in generic layer for x86 now. and maybe useful for other archs
in further.
Generic mmu_gather struct is protected by micro
HAVE_GENERIC_MMU_GATHER. Other archs that has flush range supported
own self mmu_gather struct. So, now this change is safe for them.
In future we may unify this struct and related functions on multiple
archs.
