Problems.

> Subject: [PATCH -mm 1/4] powerpc copy_siginfo_from_user32

This is advertised as a -mm patch but afacit it isn't against -mm.  And it
doesn't seem to be against mainline either?  At least, the fourth patch
fails to apply.

When trying to apply the fourth patch to -mm I hit a reject due to the new
BTS support in git-x86.  I stopped there because the patch might be invalid
because of this.

Even though this appears to be a signal-related patch it is actually
ptrace-related, yes?

This patch is a prerequisite for "ptrace: compat_ptrace_request siginfo",
but this patch is independent from that patch (and from all others) and
hence this patch can be merged on its own into powerpc tree if we wish to go that
way, yes?  (Although probably it would be better not to do it that way, for
sanity's sake).

Anwyay, please help me out with the dependencies here, and take a look at
the x86 BTS stuff?

Thanks.
