Subject: [PATCH 00/16] mm: prepare for converting vm->vm_flags to 64-bit
There is good old tradition: every year somebody submit patches for extending
vma->vm_flags upto 64-bits, because there no free bits left on 32-bit systems.
previous attempts:
https://lkml.org/lkml/2011/4/12/24 (KOSAKI Motohiro)
https://lkml.org/lkml/2010/4/27/23 (Benjamin Herrenschmidt)
https://lkml.org/lkml/2009/10/1/202 (Hugh Dickins)
Here already exist special type for this: vm_flags_t, but not all code uses it.
So, before switching vm_flags_t from unsinged long to u64 we must spread
vm_flags_t everywhere and fix all possible type-casting problems.
There is no functional changes in this patch set,
it only prepares code for vma->vm_flags converting.
