Subject: [RFC 06/17] asm-generic: add a complete signal.h
Content-Disposition: inline; filename=add-generic-signal-h.patch
X-Provags-ID: V01U2FsdGVkX1+9fyV5xiB/uv57e+JOHz1p/SO7dXImpty2qjk

There used to be an asm-generic/signal.h, but not one that
could be used out of the box. This renames the existing file
to asm-generic/signal-defs.h and adds a new asm-generic/signal.h
with common definitions for sigaction and sigaltstack, but
not for the old-style signal handlers.
New architectures should only implement rt-signals and use this
generic header.

Would you please fix your broken mail agent (quilt?), it appears to be putting
in a blank line above what you see above, which is the convention for end of
header, beginning of body, so all the people you've included above, including
the lkml, are actually getting this as private mail due to header parsing
ending prematurely.
