#     powerpc/mm/mce: Keep irqs disabled during lockless page table walk
#     
#     __find_linux_mm_pte() returns a page table entry pointer after walking
#     the page table without holding locks. 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.
#
