[patch 11/39] [PATCH] sys_signal: initialize ->sa_mask

[Chris Wright]

-stable review patch.  If anyone has any objections, please let us know.
------------------

Pointed out by Linus Torvalds.

sys_signal() forgets to initialize ->sa_mask.

( I suspect arch/ia64/ia32/ia32_signal.c:sys32_signal()
  also needs this fix )
