* um: simplify set_handler()Al Viro2011-11-024-27/+19
| | | | | | | | | | For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM), so there's no need to pass sa_mask elements in arguments. For another, the flags depend only on whether it's an IRQ signal or not (we add SA_RESTART for them).

* um: don't bother blocking SIGARLM and SIGUSR1Al Viro2011-11-023-9/+8
| | | | | | | | We used to generate those, but we hadn't done that for a long time. No need to bother blocking them for signal handlers. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

* um: get rid of sysdep/sc.hAl Viro2011-11-024-91/+15
| | | | | | | | | only sysdep/sigcontext.h uses it and very few definitions are actually used. The rest refers to symbols that don't even exist anymore anyway. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>
