alpha: Generate dwarf2 unwind info for various kernel entry points.

2013-07-19T20:54:25+00:00

Having unwind info past the PALcode generated stack frame makes
debugging the kernel significantly easier.

alpha: simplify fork and friends

2012-11-29T02:49:03+00:00

* no need to restore everything from switch_stack when we only need $26
* no need to pass current_pt_regs() manually, we can just as easily
calculate it in alpha_clone/alpha_vfork ($8 + constant)
* interpretation of zero usp as "use the parent's" is simpler in copy_thread();
let fork and vfork just pass 0.

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: 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.

alpha: simplify TIF_NEED_RESCHED handling

2012-10-12T01:39:26+00:00

In case we have both NEED_RESCHED and SIGPENDING/NOTIFY_RESUME,
handle the latter first.  We'll get to original priorities in
the next commit, but now that allows to simplify the treatment
of NEED_RESCHED-only case nicely.  Namely, now there no need to
preserve the data for restarts across the call of schedule() in
$work_resched; we can get there only if we had either returned
from syscall without SIGPENDING (in which case we should've
had no restart-worthy return value and want no restarts) or
already got through do_notify_resume() call (in which case we
want no restarts anymore).  So we can just slap 0 into $19
instead of preserving it (and $20).
