The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.
The current behaviour of cleaning the pointer is kept in the calling code,
but should be removed if not required in a later patch.

The official way to stop the display is to clear the display enable
(DEN) bit in the DSYSR register, but that operates at a group level and
affects the two channels in the group. To disable channels selectively,
the driver uses TV sync mode that stops display operation on the channel
and turns output signals into inputs.
While TV sync mode is available in all DU models currently supported,
the D3 and E3 DUs don't support it. We will thus need to find an
alternative way to turn channels off.
In the meantime, condition the switch to TV sync mode to the
availability of the feature, to avoid writing an invalid value to the
DSYSR register. When the feature is unavailable the display output will
turn blank as all planes are disabled when stopping the CRTC.

DSYSR is a DU channel register that also contains group fields. It is
thus written to by both the group and CRTC code, using read-update-write
sequences. As the register isn't initialized explicitly at startup time,
this can lead to invalid or otherwise unexpected values being written to
some of the fields if they have been modified by the firmware or just
not reset properly.
To fix this we can write a fully known value to the DSYSR register when
turning a channel's functional clock on. However, the mix of group and
channel fields complicate this. A simpler solution is to cache the
register and initialize the cached value to the desired hardware
defaults.

All Gen3 SoCs supported so far have a fixed association between DPAD0
and DU channels, which led to hardcoding that association when writing
the corresponding hardware register. The D3 and E3 will break that
mechanism as DPAD0 can be dynamically connected to either DU0 or DU1.
Make DPAD0 routing dynamic on Gen3. To ensure a valid hardware
configuration when the DU starts without the RGB output enabled, DPAD0
is associated at initialization time to the first DU channel that it can
be connected to. This makes no change on Gen2 as all Gen2 SoCs can
connected DPAD0 to DU0, which is the current implicit default value.
As the DPAD0 source is always 0 when a single source is possible on
Gen2, we can also simplify the Gen2 code in the same function to remove
a conditional check.

On selected SoCs, the DU can use the clock output by the LVDS encoder
PLL as its input dot clock. This feature is optional, but on the D3 and
E3 SoC it is often the only way to obtain a precise dot clock frequency,
as the other available clocks (CPG-generated clock and external clock)
usually have fixed rates.
Add a DU model information field to describe which DU channels can use
the LVDS PLL output clock as their input clock, and configure clock
routing accordingly.
This feature is available on H2, M2-W, M2-N, D3 and E3 SoCs, with D3 and
E3 being the primary targets. It is left disabled in this commit, and
will be enabled per-SoC after careful testing.
At the hardware level, clock routing is configured at runtime in two
steps, first selecting an internal dot clock between the LVDS PLL clock
and the external DOTCLKIN clock, and then selecting between the internal
dot clock and the CPG-generated clock. The first part requires stopping
the whole DU group in order for the change to take effect, thus causing
flickering on the screen. For this reason we currently hardcode the
clock source to the LVDS PLL clock if available, and allow flicker-free
selection of the external DOTCLKIN clock or CPG-generated clock
otherwise. A more dynamic clock selection process can be implemented
later if the need arises.

The LVDS encoders in the D3 and E3 SoCs differ significantly from those
in the other R-Car Gen3 family members:
- The LVDS PLL architecture is more complex and requires computing PLL
parameters manually.
- The PLL uses external clocks as inputs, which need to be retrieved
from DT.
- In addition to the different PLL setup, the startup sequence has
changed *again* (seems someone had trouble making his/her mind).
Supporting all this requires DT bindings extensions for external clocks,
brand new PLL setup code, and a few quirks to handle the differences in
the startup sequence.
The implementation doesn't support all hardware features yet, namely
- Using the LV[01] clocks generated by the CPG as PLL input.
- Providing the LVDS PLL clock to the DU for use with the RGB output.
Those features can be added later when the need will arise.

Klaus Kusche reported that the I/O busy time in /proc/diskstats was not
updating properly on 4.18. This is because we started using ktime to
track elapsed time, and we convert nanoseconds to jiffies when we update
the partition counter. However, this gets rounded down, so any I/Os that
take less than a jiffy are not accounted for. Previously in this case,
the value of jiffies would sometimes increment while we were doing I/O,
so at least some I/Os were accounted for.
Let's convert the stats to use nanoseconds internally. We still report
milliseconds as before, now more accurately than ever. The value is
still truncated to 32 bits for backwards compatibility.

I swear I would have sent it the same to Linus! The main cause for

It's mostly small bugfixes and cleanups, mostly around x86 nested
virtualization. One important change, not related to nested
virtualization, is that the ability for the guest kernel to trap CPUID
instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is now
masked by default. This is because the feature is detected through an
MSR; a very bad idea that Intel seems to like more and more. Some
applications choke if the other fields of that MSR are not initialized
as on real hardware, hence we have to disable the whole MSR by default,
as was the case before Linux 4.12.

CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is
now masked by default. This is because the feature is detected
through an MSR; a very bad idea that Intel seems to like more and
more. Some applications choke if the other fields of that MSR are
not initialized as on real hardware, hence we have to disable the
whole MSR by default, as was the case before Linux 4.12."

We met a kernel panic when enabling earlycon, which is due to the fixmap
address of earlycon is not statically setup.
Currently the static fixmap setup in head_64.S only covers 2M virtual
address space, while it actually could be in 4M space with different
kernel configurations, e.g. when VSYSCALL emulation is disabled.
So increase the static space to 4M for now by defining FIXMAP_PMD_NUM to 2,
and add a build time check to ensure that the fixmap is covered by the
initial static page tables.
Fixes: 1ad83c858c ("x86_64,vsyscall: Make vsyscall emulation configurable")
