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.

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.
