[PATCH] missing bit from signal patches - take 2 (or 3)

[Stephen Rothwell]

Hi Linus,

The following should allow the affected architectures to build in
2.5.19 as currently there will be two definitions of
copy_siginfo_to_user and if an architecture defines its own
siginfo_t it MUST define copy_siginfo().

Please apply.  This one should have a better chance of working :-)
