Max Filippov e28bace5e7 xtensa: define update_mmu_tlb function ... commit 1c4664faa3 upstream. Before the commit f9ce0be71d ("mm: Cleanup faultaround and finish_fault() codepaths") there was a call to update_mmu_cache in alloc_set_pte that used to invalidate TLB entry caching invalid PTE that caused a page fault. That commit removed that call so now invalid TLB entry survives causing repetitive page faults on the CPU that took the initial fault until that TLB entry is occasionally evicted. This issue is spotted by the xtensa TLB sanity checker. Fix this issue by defining update_mmu_tlb function that flushes TLB entry for the faulting address.
