m68k: add TIF_NOTIFY_RESUME and handle it.
TIF_NOTIFY_RESUME added (as bit 5). That way nommu glue needs no changes at all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead of checking that MSBit is set (jmi) we check that MSBit or something below it is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is set". Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue calls it instead of do_signal(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
