Use the newly added compound devmap facility which maps the assigned dax
ranges as compound pages at a page size of @align.
dax devices are created with a fixed @align (huge page size) which is
enforced through as well at mmap() of the device. Faults, consequently
happen too at the specified @align specified at the creation, and those
don't change throughout dax device lifetime. MCEs unmap a whole dax
huge page, as well as splits occurring at the configured page size.
Performance measured by gup_test improves considerably for
unpin_user_pages() and altmap with NVDIMMs:
$ gup_test -f /dev/dax1.0 -m 16384 -r 10 -S -a -n 512 -w
(pin_user_pages_fast 2M pages) put:~71 ms -> put:~22 ms
[altmap]
(pin_user_pages_fast 2M pages) get:~524ms put:~525 ms -> get: ~127ms put:~71ms
$ gup_test -f /dev/dax1.0 -m 129022 -r 10 -S -a -n 512 -w
(pin_user_pages_fast 2M pages) put:~513 ms -> put:~188 ms
[altmap with -m 127004]
(pin_user_pages_fast 2M pages) get:~4.1 secs put:~4.12 secs -> get:~1sec put:~563ms
.. as well as unpin_user_page_range_dirty_lock() being just as effective
as THP/hugetlb[0] pages.

Normally, the @page mapping is set prior to inserting the page into a
page table entry. Make device-dax adhere to the same ordering, rather
than setting mapping after the PTE is inserted.
The address_space never changes and it is always associated with the
same inode and underlying pages. So, the page mapping is set once but
cleared when the struct pages are removed/freed (i.e. after
{devm_}memunmap_pages()).

Right now, only static dax regions have a valid @pgmap pointer in its
struct dev_dax. Dynamic dax case however, do not.
In preparation for device-dax compound devmap support, make sure that
dev_dax pgmap field is set after it has been allocated and initialized.
dynamic dax device have the @pgmap is allocated at probe() and it's
managed by devm (contrast to static dax region which a pgmap is provided
and dax core kfrees it). So in addition to ensure a valid @pgmap, clear
the pgmap when the dynamic dax device is released to avoid the same
pgmap ranges to be re-requested across multiple region device reconfigs.
Add a static_dev_dax() and use that helper in dev_dax_probe() to ensure
the initialization differences between dynamic and static regions are
more explicit. While at it, consolidate the ranges initialization when
we allocate the @pgmap for the dynamic dax region case. Also take the
opportunity to document the differences between static and dynamic da
regions.

Even if it's probably not really useful, it can get selected
by e.g. randconfig builds, and then failing to compile is an
annoyance. Unfortunately, it's hard to fix in Kconfig, since
DRM_TTM is selected by many things that don't really depend
on any specific architecture, and just depend on PCI (which
is indeed now available in ARCH=um via simulation/emulation).
Fix this in the code instead by just ifdef'ing the relevant
two lines that depend on "real X86".

Pull irq updates from Thomas Gleixner:
"Updates for the interrupt subsystem:
Core:
- Provide a new interface for affinity hints to provide a separation
between hint and actual affinity change which has become a hidden
property of the current interface
- Fix up the in tree usage of the affinity hint interfaces
Drivers:
- No new irqchip drivers!
- Fix GICv3 redistributor table reservation with RT across kexec
- Fix GICv4.1 redistributor view of the VPE table across kexec
- Add support for extra interrupts on spear-shirq
- Make obtaining some interrupts optional for the Renesas drivers
- Various cleanups and bug fixes"
