[RFC PATCH 0/4] powerpc/pseries: Machien check handler improvements.

[Mahesh J Salgaonkar]

This patch series includes some improvement to Machine check handler
for pseries. Patch 1 fixes an issue where machine check handler crashes
kernel while accessing vmalloc-ed buffer while in nmi context.
Patch 3 dumps the SLB contents on SLB MCE errors to improve the debugability.
Patch 4 display's the MCE error details on console.
