mm: add MAP_HUGETLB for mmaping pseudo-anonymous huge page regions
...
Add a flag for mmap that will be used to request a huge page region that
will look like anonymous memory to user space. This is accomplished by
using a file on the internal vfsmount. MAP_HUGETLB is a modifier of
MAP_ANONYMOUS and so must be specified with it. The region will behave
the same as a MAP_ANONYMOUS region using small pages.
The patch also adds the MAP_STACK flag, which was previously defined only
on some architectures but not on others. Since MAP_STACK is meant to be a
hint only, architectures can define it without assigning a specific
meaning to it.

ksm: define MADV_MERGEABLE and MADV_UNMERGEABLE
...
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.
