      open*(2) compat fixes (s390, arm64) · 9d73fc2d
      Al Viro authored
      The usual rules for open()/openat()/open_by_handle_at() are
       1) native 32bit - don't force O_LARGEFILE in flags
       2) native 64bit - force O_LARGEFILE in flags
       3) compat on 64bit host - as for native 32bit
       4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for
          native 64bit
      There are only two exceptions - s390 compat has open() forcing
      O_LARGEFILE and arm64 compat has open_by_handle_at() doing the same
      thing.  The same binaries on native host (s390/31 and arm resp.) will
      *not* force O_LARGEFILE, so IMO both are emulation bugs.
      Objections? The fix is obvious...

      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.
