2012-08-27	MIPS: mm: Add compound tail page _mapcount when mapped	Jovi Zhang	1	-0/+2
	See commit b6999b191 which did the same modification for x86's mm/gup, Quote from commit b6999b191: "If compound pages are used and the page is a tail page, gup_huge_pmd() increases _mapcount to record tail page are mapped while gup_huge_pud does not do that." [ralf@linux-mips.org: fixed rejects caused by the original patch getting linewrapped.] Signed-off-by: Jovi Zhang <boojovi@gmail.com> Cc: Youquan Song <youquan.song@intel.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: <stable@vger.kernel.org> Patchwork: https://patchwork.linux-mips.org/patch/4291/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-12-08	MIPS: Add fast get_user_pages	Hillf Danton	1	-0/+315
	Gup is used in a few cases, say futex. This work is derived from the x86 version, and operations of pte and pmd are adapted to the defines of MIPS in straight forward manner. [ralf@linux-mips.org: Fixed up reject in arch/mips/mm/Makefile due to whitespace formatting differences. Fixed build error in gup.c due to conflicting changes elsewhere in the kernel.] Signed-off-by: Hillf Danton <dhillf@gmail.com> Cc: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2859/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
