alpha: pass k_sigaction and siginfo_t using ksignal pointer

2013-02-14T14:21:16+00:00

... and use the new helpers

alpha: get rid of switch_stack argument of do_work_pending()

2012-10-12T01:40:13+00:00

... and now the asm glue side of that.

alpha: don't bother passing switch_stack separately from regs

2012-10-12T01:39:28+00:00

It's needed only in setup_sigcontext() and it's always reg - ;
no point passing it all way down through the call chain.  This is just
the signal.c side of that stuff; next will come the asm glue one...

alpha: take SIGPENDING/NOTIFY_RESUME loop into signal.c

2012-10-12T01:39:27+00:00

Turn the slow side of work_pending into C function, including all
the looping.  What we get out of that:
	* we do _not_ call get_signal_to_deliver() with IRQs disabled
anymore
	* no need to save/restore volatiles on each pass if there
turns to be more than one (unlikely, but still)
	* all double-restart prevention is in C now.
	* glue gets simpler.

new helper: signal_delivered()

2012-06-01T16:58:52+00:00

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

2012-06-01T16:58:51+00:00

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.
