Pull second set of arm64 updates from Catalin Marinas:
"A second pull request for this merging window, mainly with fixes and
docs clarification:
- Documentation clarification on CPU topology and booting
requirements
- Additional cache flushing during boot (needed in the presence of
external caches or under virtualisation)
- DMA range invalidation fix for non cache line aligned buffers
- Build failure fix with !COMPAT
- Kconfig update for STRICT_DEVMEM"
* tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: Fix DMA range invalidation for cache line unaligned buffers
arm64: Add missing Kconfig for CONFIG_STRICT_DEVMEM
arm64: fix !CONFIG_COMPAT build failures
Revert "arm64: virt: ensure visibility of __boot_cpu_mode"

With system caches for the host OS or architected caches for guest OS we
cannot easily guarantee that there are no dirty or stale cache lines for
the areas of memory written by the kernel during boot with the MMU off
(therefore non-cacheable accesses).
This patch adds the necessary cache maintenance during boot and relaxes
the booting requirements.

The ARMv8 code will reject incomplete topologies that omit some CPUs (and it's
not clear that it's ever sensible to do so). Update the binding document to
make this clear.
Since we're reformatting the text also fix incorrect grammar in the
final "Any other configuration..." section by removing "consider".

Merge window -fixes pull request as usual. Well, I did sneak in Jani's
drm_i915_private_t typedef removal, need to have fun with a big sed job
too ;-)
Otherwise:
- hdmi interlaced fixes (Jesse&Ville)
- pipe error/underrun/crc tracking fixes, regression in late 3.14-rc (but
not cc: stable since only really relevant for igt runs)
- large cursor wm fixes (Chris)
- fix gpu turbo boost/throttle again, was getting stuck due to vlv rps
patches (Chris+Imre)
- fix runtime pm fallout (Paulo)
- bios framebuffer inherit fix (Chris)
- a few smaller things

The i2c client was previously being passed into the hdmi driver via a
dedicated i2c driver, and then a global variable. This patch removes all
of that and just uses the device tree to get the i2c_client. This patch
also properly references the client so we don't lose it before we're

- Tune down yelling RETURNS.
- OCD align all the parameters the same.
- Add missing kerneldoc, which also means that we need to include the
kerneldoc from the drm_modes.h header now.
- Add missing Returns: sections.
- General polish and clarification - especially the kerneldoc for the
mode creation helpers seems to have been some good specimen of
copypasta gone wrong.
All actual code changes have all been extracted into prep patches
since there was simply too much to polish.
v2: More polish for the command line modeline functions.

While at it do a tiny bit of interface cleanup and convert boolean
return values to bool. With this patch all exported functions and inline
helpers which are part of the drm_mm public interface are documented.
Also drop superflous extern function modifiers since most of drm_mm.h
doesn't use them - more consistent that way.

Hopefully documenting the lru scan support a bit better spurs someone
to give this a shot in the ttm eviction code. At least in i915 it
helped quite a lot with memory thrashing on platforms where eviction
was (we've fixed that too meanwhile) fairly expensive.

For giant hilarity the DocBook reference overview is only generated
when in a level 2 section, not in a level 3 section. So we need to
move this up a bit as a side-by-side section to the main PRIME
documentation.
Whatever.
To have a complete set of references add the missing kerneldoc for all
functions exported to modules with the exception of the file private
init/destroy functions - drivers have no business calling those, so
let's just drop the EXPORT_SYMBOL instead.
Also reflow the function parameters to align correctly and break at 80
chars - my OCD couldn't stand them while writing the kerneldoc ;-)

PRIME fds aren't actually GEM fds but are (like the modeset API)
independent of the underlying buffer manager, as long as that one uses
uint32_t as handles. So move that entire section out of the GEM
section and reword it a bit to clarify which parts of PRIME are
generic, and which are the mandatory pieces for GEM drivers to
correctly implement the GEM lifetime rules. The rewording mostly
consists of not mixing up GEM, PRIME and DRM.
I've considered adding some blurbs to the GEM object lifetime section
about interactions with dma-bufs, but then dropped that. As long as
drivers use the right helpers they should have this all implemented
correctly and hence can be regarded as an implementation detail of the
PRIME/GEM helpers. So no need to confuse driver writers with those
tricky interactions.

Thierry created such nice kerneldocs, it's a shame we've left them
lingering!
For the fun of it also add a bit of kerneldoc to the header so that we
can also include that. Just in case someone adds kerneldoc in there.

By consolidating them all into one section at the very end. And to
make double-sure that no one gets confused start with a stern warning
against any use of them. And prefix all subsections with "Legacy".

Currently it's sitting in the mode setting helper section, which isn't
quite right. Looks much better in the memory management section next
to TTM and GEM.

- This is _not_ a generic interface to create gem objects, but just an
interface to make early boot services (like boot splash) with a
generic KMS userspace driver possible. Hence it's better to move
the documentation for this from the GEM section to the KMS section,
next to the creation of framebuffer objects.
- Make it really clear that the returned handle isn't necessarily a
GEM object (it can also be e.g. a TTM handle when running on top of
vmwgfx).
- Add a paragraph to make it clear that this is just for unaccelarated
userspace - gpu drivers need to have their own buffer object
creation ioctl which is hardware specific.
v2: Clarify that the documentation doesn't just apply to GEM-based
drivers only but is now generally valid, as suggested by David.
v3: Polish the intro sentence a bit and one s/objects/handles/ for
clarification, both suggested by Laurent.
v4: More text polish from Laurent's review.
v5: More typo fixes from Dieter.

into drm-next
Updates from Jean-Fracois for the TDA998x driver, which are on top of
the fixes you have previously pulled, except these changes aren't
intended for -rc, but the next merge window.
Several of these are issues of correctness - passing more correct HDMI
info packets, not reading registers in older chips documented as write
only (despite appearing to be read/write in later chips). Others are
code cleanups (using definitions rather than constants where we have
them already in the kernel).
Additional functionality is also added by way of optional support for
the IRQ from the TDA998x, which allows us to avoid busy-waiting for
the EDID reads.
* 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox:
drm/i2c: tda998x: always use the same device for all kernel messages
drm/i2c: tda998x: adjust the audio clock divider for S/PDIF
drm/i2c: tda998x: code optimization
drm/i2c: tda998x: remove the unused variable ca_i2s
drm/i2c: tda998x: make the audio code more readable
drm/i2c: tda998x: use irq for connection status and EDID read
drm/i2c: tda998x: always enable EDID read IRQ
drm/i2c: tda998x: add DT documentation
drm/i2c: tda998x: add DT support
drm/i2c: tda998x: don't read write-only registers
drm/i2c: tda998x: don't freeze the system at audio startup time
drm/i2c: tda998x: change probe message origin
drm/i2c: tda998x: code cleanup
drm/i2c: tda998x: clean up error chip version checking
drm/i2c: tda998x: check more I/O errors
drm/i2c: tda998x: simplify the i2c read/write functions
drm/i2c: tda998x: use ALSA IEC958 definitions and update audio frequency
drm/i2c: tda998x: add the active aspect in HDMI AVI frame
drm/i2c: tda998x: use HDMI constants

Pull kbuild changes from Michal Marek:

- make O=... directory is automatically created if needed
- mrproper/distclean removes the old include/linux/version.h to make
life easier when bisecting across the commit that moved the version.h
file

kbuild: create a build directory automatically for out-of-tree build
kbuild: remove redundant '.*.cmd' pattern from make distclean
kbuild: move "quote" to Kbuild.include to be consistent
kbuild: docbook: use $(obj) and $(src) rather than specific path
kbuild: unconditionally clobber include/linux/version.h on distclean
kbuild: docbook: specify KERNELDOC dependency correctly
kbuild: docbook: include cmd files more simply

The commit ec3fadd64b99 (kbuild: docbook: use $(obj) and $(src) rather
than specific path) replaces the specific path with $(src). But when
executing "make help", the $(src) is null and then causes an include
error. Fix it by restoring the specific path.

It is not a good idea to describe
%.xml: %.tmpl FORCE
...
and
$(BOOKS): $(KERNELDOC)
separately. This cannot detect missing template files.
For example, add something to DOCBOOKS variable:
DOCBOOKS += foobar.xml
and run
make xmldocs
It will succeed even if Documention/DocBook/foobar.tmpl
does not exist.

Add support for early IO or memory mappings which are needed before the
normal ioremap() is usable. This also adds fixmap support for permanent
fixed mappings such as that used by the earlyprintk device register
region.
