If we need to force a full plane update before userspace/fbdev
have given us a proper plane state we should try to maintain the
current plane state as much as possible (apart from the parts
of the state we're trying to fix up with the plane update).
To that end add basic readout for the plane rotation and
maintain it during the initial fb takeover.

If we force a plane update to fix up our half populated plane state
we'll also force on the pipe gamma for the plane (since we always
enable pipe gamma currently). If the BIOS hasn't programmed a sensible
LUT into the hardware this will cause the image to become corrupted.
Typical symptoms are a purple/yellow/etc. flash when the driver loads.
To avoid this let's program something sensible into the LUT when
we do the plane update. In the future I plan to add proper plane
gamma enable readout so this is just a temporary measure.

Depending on the transcoder enum values to translate from transcoder to

new transcoder. Add an explicit mapping instead, by using helpers to
look up the register instance either by transcoder or port (since
unconveniently the registers have both port and transcoder specific

QEMU keeps a vram reference to the last QXLCursorCmd it received.
This QXLCursorCmd command points to a QXLCursor instance (stored in vram
too). However, while the QXLCursorCmd memory is pinned, the QXLCursor
memory is not.
When booting a recent Fedora to its login screen while monitoring the
QXLCursorCmd QEMU holds, it's possible to see the QXLCursor memory
becoming invalid shortly after boot. Pinning that memory ensures that
that QXLCursor memory is not going to be moved by the guest kernel.
Moving the pin/unpin to qxl_release_list_add()/qxl_release_free_list()
would be a more generic fix. However, doing this quickly exhausts QXL
video memory, so more fixing would be needed before this is workable.

This adds an optional function table on GEM objects.
The main benefit is for drivers that support more than one type of
memory (shmem,vram,cma) for their buffers depending on the hardware it
runs on. With the callbacks attached to the GEM object itself, it is
easier to have core helpers for the the various buffer types. The driver
only has to make the decision about buffer type on GEM object creation
and all other callbacks can be handled by the chosen helper.
drm_driver->gem_prime_res_obj has not been added since there's a todo to

Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block)
allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is
used by them, can read only up to 255 bytes at once. Normally, it's
not a big issue as DPCD or EDID reads won't (hopefully) exceed that
value.
The real issue here is the revocation list read during the HDCP
authentication process. (problematic use case:
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152)
The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv +
4 bytes of an additional info).

Pull libnvdimm fixes from Dan Williams:
"A small batch of fixes for v4.20-rc3.
The overflow continuation fix addresses something that has been broken
for several releases. Arguably it could wait even longer, but it's a
one line fix and this finishes the last of the known address range
scrub bug reports. The revert addresses a lockdep regression. The unit
tests are not critical to fix, but no reason to hold this fix back.
Summary:
- Address Range Scrub overflow continuation handling has been broken
since it was initially merged. It was only recently that error
injection and platform-BIOS support enabled this corner case to be
exercised.
- The recent attempt to provide more isolation for the kernel Address
Range Scrub state machine from userapace initiated sessions
triggers a lockdep report. Revert and try again at the next merge
window.

Pull ARM spectre updates from Russell King:
"These are the currently known final bits that resolve the Spectre
issues. big.Little systems used to be sufficiently identical in that
there were no differences between individual CPUs in the system that
mattered to the kernel. With the advent of the Spectre problem, the
CPUs now have differences in how the workaround is applied.
As a result of previous Spectre patches, these systems ended up
reporting quite a lot of:
"CPUx: Spectre v2: incorrect context switching function, system vulnerable"
messages due to the action of the big.Little switcher causing the CPUs
to be re-initialised regularly. This series resolves that issue by
making the CPU vtable unique to each CPU.
However, since this is used very early, before per-cpu is setup,
per-cpu can't be used. We also have a problem that two of the methods
are not called from preempt-safe paths, but thankfully these remain
identical between all CPUs in the system. To make sure, we validate
that these are identical during boot"
* 'spectre' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: spectre-v2: per-CPU vtables to work around big.Little systems
ARM: add PROC_VTABLE and PROC_TABLE macros
ARM: clean up per-processor check_bugs method call
ARM: split out processor lookup
ARM: make lookup_processor_type() non-__init
