  "message": "[PATCH] mm: move_pte to remap ZERO_PAGE\n\nMove the ZERO_PAGE remapping complexity to the move_pte macro in\nasm-generic, have it conditionally depend on\n__HAVE_ARCH_MULTIPLE_ZERO_PAGE, which gets defined for MIPS.\n\nFor architectures without __HAVE_ARCH_MULTIPLE_ZERO_PAGE, move_pte becomes\na noop.\n\nFrom: Hugh Dickins \u003chugh@veritas.com\u003e\n\nFix nasty little bug we\u0027ve missed in Nick\u0027s mremap move ZERO_PAGE patch.\nThe \"pte\" at that point may be a swap entry or a pte_file entry: we must\ncheck pte_present before perhaps corrupting such an entry.\n\nPatch below against 2.6.14-rc2-mm1, but the same bug is in 2.6.14-rc2\u0027s\nmm/mremap.c, and more dangerous there since it\u0027s affecting all arches: I\nthink the safest course is to send Nick\u0027s patch and Yoichi\u0027s build fix and\nthis fix (build tested) on to Linus - so only MIPS can be affected.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
