powerpc/mm: Remove stale do_page_fault comment referring to SLB faults
SLB faults no longer call do_page_fault, this was removed somewhere between 2.6.0 and 2.6.12. Signed-off-by: Nicholas Piggin <[email protected]> Signed-off-by: Michael Ellerman <[email protected]> Link: https://lore.kernel.org/r/[email protected]
