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

2013-07-19T20:54:25Z

Having unwind info past the PALcode generated stack frame makes debugging the kernel significantly easier. Acked-by: Matt Turner Signed-off-by: Matt Turner Signed-off-by: Richard Henderson

alpha: simplify fork and friends

2012-11-29T02:49:03Z

* 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: take SIGPENDING/NOTIFY_RESUME loop into signal.c

2012-10-12T01:39:27Z

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

2012-10-12T01:39:26Z

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). Signed-off-by: Al Viro
