The extra DPLL power domain is currently handled in three places:
- combo_pll_enable()
- combo_pll_disable()
- readout_dpll_hw_state()
First two of those are low level PLL funcs, but the third is a higher
level thing. So the current situation is rather inconsistent. Unify
this by moving the PLL enable/disable up one level. This also means
the extra power domain could be trivially be used by other platforms
as well.

Just include the JSL/EHL DPLL4 extra power domain in the dpll_info
struct. This way the same approach could be used by other platforms
as well (should the need arise), and we don't have to sprinkle
platform checks all over the place.
Note that I'm perhaps slightly abusing things here as
power_domain==0 (which is actually POWER_DOMAIN_DISPLAY_CORE) now
indicates that no extra power domain is needed. I suppose using
POWER_DOMAIN_INVALID would be more correct, but then we'd have to
sprinkle that to all the other DPLLs.

Apparently some BDW machines (eg. HP Pavilion 15-ab) shipped with
a VBT inherited from some earlier HSW model. On HSW the HDMI level
shift value could go up to 11, whereas on BDW the maximum value is
9.
The DDI code does clamp the bogus value, but it does so with
a WARN which we don't really want. To avoid that let's just sanitize
the bogus VBT HDMI level shift value ahead of time for all BDW machines.

Pull execve updates from Kees Cook:
- Support non-BSS ELF segments with zero filesz
Eric Biederman and I refactored ELF segment loading to handle the
case where a segment has a smaller filesz than memsz. Traditionally
linkers only did this for .bss and it was always the last segment. As
a result, the kernel only handled this case when it was the last
segment. We've had two recent cases where linkers were trying to use
these kinds of segments for other reasons, and the were in the middle
of the segment list. There was no good reason for the kernel not to
support this, and the refactor actually ends up making things more
readable too.
- Enable namespaced binfmt_misc
Christian Brauner has made it possible to use binfmt_misc with mount
namespaces. This means some traditionally root-only interfaces (for
adding/removing formats) are now more exposed (but believed to be
safe).
- Remove struct tag 'dynamic' from ELF UAPI
Alejandro Colomar noticed that the ELF UAPI has been polluting the
struct namespace with an unused and overly generic tag named
"dynamic" for no discernible reason for many many years. After
double-checking various distro source repositories, it has been
removed.

provided by NVIDIA, bringing with it the beginnings of Ada support.
Until it's had more testing and time to bake, support is disabled by
default (except on Ada). GSP-RM usage can be enabled by passing the
"config=NvGspRm=1" module option.

- on HW, parts of this will still be used to support LVDS
- LVDS appears to have dissapeared before Turing, so this won't be

- (temporarily) disable if GSP-RM detected, will be added later
- provide empty class list for non-GSP paths
- split tu102 from gm107, it will provide host classes later

- add (initial) R535 implementation of FB, need VRAM size etc for boot
- expose a way to "wrap" vram at a specific address/size as a standard
nvkm_memory allocation, which will be used to write PTEs etc for RM-
defined memory regions
