Subject: [PATCH v3 0/2] powerpc/ptrace: Hard wire PT_SOFTE value to 1 in
 gpr_get() too

Can we finally fix this problem? ;)

My previous attempt was ignored, see

	https://lore.kernel.org/lkml/20190917121256.GA8659@redhat.com/

Now that gpr_get() was changed to use membuf API we can make a simpler fix.

Sorry, uncompiled/untested, I don't have a ppc machine.

Oleg.
