[PATCH 00/13] convert more vm_flags_t users to vma_flags_t

[Lorenzo Stoakes <ljs@xxxxxxxxxx>]

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.

Lorenzo Stoakes (13):
  mm: introduce vma_flags_can_grow() and vma_can_grow()
  mm/vma: update do_mmap() to use vma_flags_t
  mm: convert __get_unmapped_area() to use vma_flags_t
  mm: update generic_get_unmapped_area[_topdown]() to use vma_flags_t
  mm: prefer mm->def_vma_flags in mm logic
  mm/vma: convert vm_pgprot_modify() to use vma_flags_t and rename
  mm/vma: rename vma_get_page_prot to vma_flags_to_page_prot
  mm: introduce vma_get_page_prot() and use it
  mm/vma: update create_init_stack_vma() to use vma_flags_t
  mm/vma: convert miscellaneous uses of VMA flags in core mm
  mm/mlock: convert mlock code to use vma_flags_t
  mm/mprotect: convert mprotect code to use vma_flags_t
  mm/mremap: convert mremap code to use vma_flags_t
