[PATCH] SELinux: add task_movememory hook
This patch adds new security hook, task_movememory, to be called when memory
owened by a task is to be moved (e.g. when migrating pages to a this hook is

to allow this check to be specialized in the future if necessary.
Since the last posting, the hook has been renamed following feedback from
Christoph Lameter.
