David S. Miller a9546f59e9 [PATCH] sparc64: Do not flush dcache for ZERO_PAGE. ... This case actually can get exercised a lot during an ELF coredump of a process which contains a lot of non-COW'd anonymous pages. GDB has this test case which in partiaular creates near terabyte process full of ZERO_PAGEes. It takes forever to just walk through the page tables because of all of these spurious cache flushes on sparc64. With this change it takes only a second or so. Signed-off-by: David S.
