This series makes further progress in converting usage of the deprecated
vm_flags_t type to its replacement, vma_flags_t.

It focuses on mm, though updates some users of mm APIs also.

It updates:

* The core do_mmap() code path for VMA mapping.
* Unmapped area logic.
* The usage of mm->def_vma_flags.
* VMA page protection bit logic.
* General usage of VMA flags in core mm code, mlock, mprotect, mremap.

REVIEWER/MERGER NOTE: This is dependent on [0], which must be merged before
this.

Changes in v2:
* Rebased on to mm-new that has the 33 patch rework dependency in it.
* Distributed tags, thanks everybody!
* Moved VMA_STACK_INCOMPLETE_SETUP and VMA_STACK_EARLY VMA userland test defines
  from 1/13 to 9/13 as per Zi.
* Fixed whitespace in 3/13 as per Zi.
* Updated 5/13 to use %*pb formatter for VMA flags (to match mm flags formatter)
  in dump_mm(), as per Lance.
* Updated 8/13 to update panthor_gem.c to vma_get_page_prot() as per Lance.
* Fixed up comment type in 11/13 as per Lance.
* Fixed bug of using VMA_GROWSUP_BIT rather than VMA_GROWSUP as per Lance
  in 12/13.
* Added detail about when we are and are not required to open code
  vma_write_lock() for VMA flag mutators in the commit message for 13/13 as
  per Lance and Zi.
