To make it safe against a THP # split and/or collapse, we disable interrupts around the lockless page # table walk. However we need to keep interrupts disabled as long as we # use the page table entry pointer that is returned. # # Fix addr_to_pfn() to do that. # # Fixes: ba41e1e1ccb9 ("powerpc/mce: Hookup derror (load/store) UE errors") # Signed-off-by: Aneesh Kumar K.V # [mpe: Rearrange code slightly and tweak change log wording] # Signed-off-by: Michael Ellerman # Link:
