mm: split gfp_mask and mapping flags into separate fields
mapping->flags currently encodes two different things into a single flag.
It contains sticky gfp_mask for page cache allocations and AS_ codes used
to report errors/enospace and other states which are mapping specific.
Condensing the two semantically unrelated things saves few bytes but it
also complicates other things. For one thing the gfp flags space is
reduced and in fact we are already running out of available bits. It can
be assumed that more gfp flags will be necessary later on.
To not introduce the address_space grow (at least on x86_64) we can stick
it right after private_lock because we have a hole there.
