parisc: don't bother looping in do_signal()

2012-10-01T13:58:14Z

entry.S code had been looping until no pending signals are left since 2005 anyway; no need to bother with that in do_signal() itself. If the failure to set a sigframe up raises SIGSEGV, we'll just pick it up the next time around the loop(s) in entry.S anyway. Signed-off-by: Al Viro

parisc: fix double restarts

2012-10-01T13:58:13Z

Don't bother restoring r28 on syscall restarts; it's clobbered by syscall anyway. Reuse (now unused) ->orig_r28 as "no restarts allowed" flag. Signed-off-by: Al Viro

new helper: signal_delivered()

2012-06-01T16:58:52Z

Does block_sigmask() + tracehook_signal_handler(); called when sigframe has been successfully built. All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).

most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from set

2012-06-01T16:58:51Z

Only 3 out of 63 do not. Renamed the current variant to __set_current_blocked(), added set_current_blocked() that will exclude unblockable signals, switched open-coded instances to it. Signed-off-by: Al Viro

new helper: restore_saved_sigmask()

2012-06-01T16:58:47Z

first fruits of ..._restore_sigmask() helpers: now we can take boilerplate "signal didn't have a handler, clear RESTORE_SIGMASK and restore the blocked mask from ->saved_mask" into a common helper. Open-coded instances switched... Signed-off-by: Al Viro
