[PATCH v5 03/12] arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures
From: Minchan Kim <minchan@kernel.org>
Date: 2015-11-30 06:39:51
Also in:
linux-arch, linux-mm, lkml, sparclinux
Subsystem:
alpha port, generic include/asm header files, memory mapping - madvise (memory advice), mips, parisc architecture, tensilica xtensa port (xtensa), the rest · Maintainers:
Richard Henderson, Matt Turner, Magnus Lindholm, Arnd Bergmann, Andrew Morton, Liam R. Howlett, Lorenzo Stoakes, David Hildenbrand, Thomas Bogendoerfer, "James E.J. Bottomley", Helge Deller, Chris Zankel, Max Filippov, Linus Torvalds
From: Chen Gang <redacted> For uapi, need try to let all macros have same value, and MADV_FREE is added into main branch recently, so need redefine MADV_FREE for it. At present, '8' can be shared with all architectures, so redefine it to '8'.
