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:

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.
