[rfc 3/3] powerpc/mce: hookup memory_failure for UE errors

If we are in user space and hit a UE error, we now have the basic infrastructure to walk the page tables and find out the effective address that was accessed, since the DAR is not valid. We use a work_queue content to hookup the bad pfn, any other context causes problems, since memory_failure

[rfc 2/3] powerpc/mce: Extract physical_address for UE errors

Walk the page table for NIP and extract the instruction. Then use the instruction to find the effective address via analyse_instr(). We might have page table walking races, but we expect them to be rare, the physical address extraction is best effort. The idea is to then hook up this

[rfc 0/3] Revisit MCE handling for UE errors

This patch series is designed to hook up memory_failure on UE errors, this is specially helpful for user_mode UE errors. The first patch is a cleanup patch, it removes dead code. I could not find any users of get_mce_fault_addr(). The second patch walks kernel/user mode page tables in real mode

[PATCH 2/2] powerpc/powernv/npu: Don't explicitly flush nmmu tlb

The nest mmu required an explicit flush as a tlbi would not flush it in the same way as the core. However an alternate firmware fix exists which should eliminate the need for this flush, so instead add a device-tree property (ibm,nmmu-flush) on the NVLink2 PHB to enable it only if required.

[PATCH 1/2] powerpc/npu: Use flush_all_mm() instead of flush_tlb_mm()

With the optimisations introduced by commit a46cc7a908 ("powerpc/mm/radix: Improve TLB/PWC flushes"), flush_tlb_mm() no longer flushes the page walk cache with radix. Switch to using flush_all_mm() to ensure the pwc and tlb are properly flushed on the nmmu. Signed-off-by: Alistair Popple
