3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mahesh Salgaonkar <mah...@linux.vnet.ibm.com> commit 682e77c861c4c60f79ffbeae5e1938ffed24a575 upstream. The existing MCE code calls flush_tlb hook with IS=0 (single page) resulting in 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.
