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.

Change in V2:
- patch 4: Display additional info (NIP and task info) in MCE error details.
- patch 5: Fix endain bug while restoring of r3 in MCE handler.

Mahesh Salgaonkar (5):
      powerpc/pseries: convert rtas_log_buf to linear allocation.
      powerpc/pseries: Define MCE error event section.
      powerpc/pseries: Dump and flush SLB contents on SLB MCE errors.
      powerpc/pseries: Display machine check error details.
      powerpc/pseries: Fix endainness while restoring of r3 in MCE handler.
These look good, should patch 5 be moved to patch 2 and the first 2
patches marked for stable?

Do you also plan to dump SLB contents for bare metal MCEs?

Thanks,
Nick
