The out-of-tree KSM used ioctls on fds cloned from /dev/ksm to register a memory area for merging: we prefer now to use an madvise(2) interface. This patch just defines MADV_MERGEABLE (to tell KSM it may merge pages in this area found identical to pages in other mergeable areas) and MADV_UNMERGEABLE (to undo that). Most architectures use asm-generic, but alpha, mips, parisc, xtensa need their own definitions: included here for mmotm convenience, but we'll probably want to split this and feed pieces to arch maintainers. Based upon earlier patches by Chris Wright and Izik Eidus.
