[Devel] [PATCH 1/1] cr: move CKPT_ARCH_NSIG to asm/signal.h

[Serge E. Hallyn]

I dunno...  does this seem worth a shot?  Or should I just go ahead
and #define CKPT_ARCH_NSIG in arch/s390/include/asm/checkpoint_hdr.h
after all?

Subject: [PATCH 1/1] cr: move CKPT_ARCH_NSIG to asm/signal.h

Just a thought...  if the signal code changes we don't want
the checkpoint code getting out of sync.  But putting it where
it really belongs - asm/sigcontext.h - doesn't work bc that's
under ifdef __KERNEL__.  So does this seem like a reasonable thing
to do?

Also define the value for s390.
