      arm64: fix alignment padding in assembly code · aeed41a9
      Marc Zyngier authored
      An interesting effect of using the generic version of linkage.h
      is that the padding is defined in terms of x86 NOPs, which can have
      even more interesting effects when the assembly code looks like this:
      	mov	x0, xzr
      	// fall through
      	mov	x0, #1
      Admittedly, the code is not very nice. But having code from another
      architecture doesn't look completely sane either.
      The fix is to add arm64's version of linkage.h, which causes the insertion
      of proper AArch64 NOPs.

      compat: move compat_siginfo_t definition to asm/compat.h · 751f409d
      Denys Vlasenko authored
      This is a preparatory patch for the introduction of NT_SIGINFO elf note.
      Make the location of compat_siginfo_t uniform across eight architectures
      which have it.  Now it can be pulled in by including asm/compat.h or
      Most of the copies are verbatim.  compat_uid[32]_t had to be replaced by
      __compat_uid[32]_t.  compat_uptr_t had to be moved up before
      compat_siginfo_t in asm/compat.h on a several architectures (tile already
      had it moved up).  compat_sigval_t had to be relocated from linux/compat.h
      to asm/compat.h.

      UAPI: Split compound conditionals containing __KERNEL__ in Arm64 · 1c1e4362
      David Howells authored
      Split compound conditionals containing __KERNEL__ in Arm64 where possible to
      make it easier for the UAPI disintegration scripts to handle them.

      UAPI: Fix the guards on various asm/unistd.h files · 89013952
      David Howells authored
      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
      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)
      arch/unicore32/include/asm/unistd.h:#if !defined(__UNICORE_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.
