UAPI: Fix the guards on various asm/unistd.h files
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) 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.
