Subject: [PATCH] add more regs to kvm_show_regs for powerpc 
From: Christian Ehrhardt <ehrhardt-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>

This adds some registers useful for guest debugging to the powerpc code for
kvm_show_regs in libkvm.

This make "extra pages" allocation only apply to x86.
IA64 already had an exclusion and so does ppc. This patch switches the
default to no extra pages and lets I386 and X86_64 get it's 3 extra pages
as needed.
