Merge branch 'prep-for-5level'

Merge 5-level page table prep from Kirill Shutemov:
"Here's relatively low-risk part of 5-level paging patchset. Merging it
now will make x86 5-level paging enabling in v4.12 easier.

The first patch is actually x86-specific: detect 5-level paging
support. It boils down to single define.

The rest of patchset converts Linux MMU abstraction from 4- to 5-level
paging.

Enabling of new abstraction in most cases requires adding single line
of code in arch-specific code. The rest is taken care by asm-generic/.

Changes to mm/ code are mostly mechanical: add support for new page
table level -- p4d_t -- where we deal with pud_t now.

v2:
- fix build on microblaze (Michal);
- comment for __ARCH_HAS_5LEVEL_HACK in kasan_populate_zero_shadow();
- acks from Michal"

Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next-queued

Backmerge drm-next to get at all the good stuff in drm-misc. We need
that because:

- drm_connector_list_iter conversion for i915 needs the core patches.
- Maarten's patches to use the new atomic state iterators also need
the core patches.
- We need the new link status property to complete the DP retraining
work, merging through 2 branches wasn't a good idea and we had to
partially backtrack.
- Chris needs reservation_object_trylock and we want to roll out
kref_read everywhere.

mm: introduce page_vma_mapped_walk()

Introduce a new interface to check if a page is mapped into a vma. It
aims to address shortcomings of page_check_address{,_transhuge}.

Existing interface is not able to handle PTE-mapped THPs: it only finds
the first PTE. The rest lefted unnoticed.

page_vma_mapped_walk() iterates over all possible mapping of the page in
the vma.
