[PATCH] powerpc/book3s: Fix partial invalidation of TLBs in MCE code.

2014-12-04 Thread Mahesh J Salgaonkar
From: Mahesh Salgaonkar The existing MCE code calls flush_tlb hook with IS=0 (single page) resulting partial invalidation of TLBs which is not right. This patch fixes that by passing IS=0xc00 to invalidate whole TLB for successful recovery from TLB and ERAT errors. Signed-off-by: Mahesh Salgaonk
