y2038: utimes: Rework #ifdef guards for compat syscalls
After changing over to 64-bit time_t syscalls, many architectures will want compat_sys_utimensat() but not respective handlers for utime(), utimes() and futimesat(). This adds a new __ARCH_WANT_SYS_UTIME32 to complement __ARCH_WANT_SYS_UTIME. For now, all 64-bit architectures that support CONFIG_COMPAT set it, but future 64-bit architectures will not (tile would not have needed it either, but got removed). As older 32-bit architectures get converted to using CONFIG_64BIT_TIME, they will have to use __ARCH_WANT_SYS_UTIME32 instead of __ARCH_WANT_SYS_UTIME. Architectures using the generic syscall ABI don't need either of them as they never had a utime syscall. Since the compat_utimbuf structure is now required outside of CONFIG_COMPAT, I'm moving it into compat_time.h. Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- changed from last version: - renamed __ARCH_WANT_COMPAT_SYS_UTIME to __ARCH_WANT_SYS_UTIME32
