Subject: [PATCH 0/7] mm: vma->vm_flags diet

This patch-set moves/kills some VM_* flags in vma->vm_flags bit-field,
as result there appears four free bits.

Also I'm working on VM_RESERVED reorganization, probably it also can be killed.
It lost original swapout-protection sense in 2.6 and now is used for other purposes.
