[PATCH] asm/signal.h unification
New file - asm-generic/signal.h. Contains declarations of __sighandler_t, __sigrestore_t, SIG_DFL, SIG_IGN, SIG_ERR and default definitions of SIG_BLOCK, SIG_UNBLOCK and SIG_SETMASK. asm-*/signal.h switched to including it. The only exception is asm-parisc/signal.h that wants its own declaration of __sighandler_t; that one is left as-is. asm-ppc64/signal.h required one more thing - unlike everybody else it used __sigrestorer_t instead of usual __sigrestore_t. PPC64 switched to common spelling. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
