From: Peter Xu Date: Wed, 12 Aug 2020 01:38:43 +0000 (-0700) Subject: mm/sparc32: use general page fault accounting X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=56e10e6ab11924b19b7c9583750fdd4e440e25c8;p=linux.git mm/sparc32: use general page fault accounting Use the general page fault accounting by passing regs into handle_mm_fault(). It naturally solve the issue of multiple page fault accounting when page fault retry happened. Signed-off-by: Peter Xu Signed-off-by: Andrew Morton Acked-by: David S.
