sparc: unify signal.h
They were almost identical and with the preapration patch nothing was needed to be added. The unified version contains a few sparc64 only definitions but they are kept as is and not protected by ifdef/endif. The unified version exports a bit more to userspace then the 32 bit version did. This is not considered fatal. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
