[PATCH] mips: add MIPS-specific support for flatmem/discontigmem
2.6.12-git6 doesn't boot on some MIPS machines. They need the support of flat memory and discontig memory. Signed-off-by: Yoichi Yuasa <yuasa@hh.iij4u.or.jp> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
