The PTRACE_SETREGS request was only recently added on powerpc,
and gdb does not use it. So it slipped through without getting
all the testing it should have had.
The user_regset changes had a simple bug in storing to all of

I mangled the filenames and didn't notice that you fixed the header file

Define the copy_siginfo_from_user32 entry point for powerpc, so
that generic CONFIG_COMPAT code can call it. We already had the
code rolled into compat_sys_rt_sigqueueinfo, this just moves it
out into the canonical function that other arch's define.

This adds support for PTRACE_GETSIGINFO and PTRACE_SETSIGINFO in
compat_ptrace_request. It relies on existing arch definitions for
copy_siginfo_to_user32 and copy_siginfo_from_user32.
On powerpc, this fixes a longstanding regression of 32-bit ptrace
calls on 64-bit kernels vs native calls
This removes the special-case handling for PTRACE_GETSIGINFO
and PTRACE_SETSIGINFO from x86_64's sys32_ptrace. The generic
compat_ptrace_request code handles these.

Now that there are no more special cases in sys32_ptrace, we
can convert to using the generic compat_sys_ptrace entry point.
The sys32_ptrace function gets simpler and becomes compat_arch_ptrace.

Since the 970 kernel never sets DABRX currently, #8 cannot explain

That's kind of what I thought, but I couldn't make enough sense of
