| | | | | | | | | | | | | | | | | | | | Some of them use guard symbol TARGET_SYSCALL_H, but we also have CRIS_SYSCALL_H, MICROBLAZE_SYSCALLS_H, TILEGX_SYSCALLS_H and __UC32_SYSCALL_H__. They all upset scripts/clean-header-guards.pl. Reuse of the same guard symbol TARGET_SYSCALL_H in multiple headers is okay as long as they cannot be included together. The script can't tell, so it warns. The script dislikes the other guard symbols, too. They don't match their file name (they should, to make guard collisions less likely), and __UC32_SYSCALL_H__ is a reserved identifier.
