    y2038: utimes: Rework #ifdef guards for compat syscalls · 4faea239
    Arnd Bergmann authored
    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.

    changed from last version:
    - renamed __ARCH_WANT_COMPAT_SYS_UTIME to __ARCH_WANT_SYS_UTIME32
