mm: Add write-protect and clean utilities for address space ranges
Add two utilities to a) write-protect and b) clean all ptes pointing into
a range of an address space.
The utilities are intended to aid in tracking dirty pages (either
driver-allocated system memory or pci device memory).
The write-protect utility should be used in conjunction with
page_mkwrite() and pfn_mkwrite() to trigger write page-faults on page
accesses. Typically one would want to use this on sparse accesses into
large memory regions. The clean utility should be used to utilize
hardware dirtying functionality and avoid the overhead of page-faults,
typically on large accesses into small memory regions.
The added file "as_dirty_helpers.c" is initially listed as maintained by
VMware under our DRM driver. If somebody would like it elsewhere,
that's of course no problem.
Notable changes since RFC:
- Added comments to help avoid the usage of these function for VMAs
it's not intended for. We also do advisory checks on the vm_flags and
warn on illegal usage.
- Perform the pte modifications the same way softdirty does.
- Add mmu_notifier range invalidation calls.
- Add a config option so that this code is not unconditionally included.
- Tell the mmu_gather code about pending tlb flushes.

mm: Add an apply_to_pfn_range interface
This is basically apply_to_page_range with added functionality:
Allocating missing parts of the page table becomes optional, which
means that the function can be guaranteed not to error if allocation
is disabled. Also passing of the closure struct and callback function
becomes different and more in line with how things are done elsewhere.
Finally we keep apply_to_page_range as a wrapper around apply_to_pfn_range
The reason for not using the page-walk code is that we want to perform
the page-walk on vmas pointing to an address space without requiring the
mmap_sem to be held rather than on vmas belonging to a process with the
mmap_sem held.
Notable changes since RFC:

drm/vmwgfx: Assign eviction priorities to resources
TTM provides a means to assign eviction priorities to buffer object. This
means that all buffer objects with a lower priority will be evicted first
on memory pressure.
Use this to make sure surfaces and in particular non-dirty surfaces are
evicted first. Evicting in particular shaders, cotables and contexts imply
a significant performance hit on vmwgfx, so make sure these resources are
evicted last.
Some buffer objects are sub-allocated in user-space which means we can have
many resources attached to a single buffer object or resource. In that case
the buffer object is given the highest priority of the attached resources.

drm/fb-helper: Remove drm_fb_helper_crtc
struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so
use that directly instead and attach it as a modeset array onto
drm_client_dev. drm_fb_helper will use this array to store its modesets
which means it will always initialize a drm_client, but it will not
register the client (callbacks) unless it's the generic fbdev emulation.
Code will later be moved to drm_client, so add code there in a new file
drm_client_modeset.c with MIT license to match drm_fb_helper.c.
The modeset connector array size is hardcoded for the cloned case to avoid
having to pass in a value from the driver. A value of 8 is chosen to err
on the safe side. This means that the max connector argument for
drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore,
a todo entry for this is added.
In pan_display_atomic() restore_fbdev_mode_force() is used instead of
restore_fbdev_mode_atomic() because that one will later become internal
to drm_client_modeset.

1. drm_fb_helper->lock
2. drm_master_internal_acquire
3. drm_client_dev->modeset_mutex

drm/amd/display: Only force modesets when toggling HDR

We can issue HDR static metadata as part of stream updates for
non-modesets as long as we force a modeset when entering or exiting HDR.
This avoids unnecessary blanking for simple metadata updates.

When changing scaling and abm for the stream also check if HDR has
changed and send the stream update. This will only happen in non-modeset

drm/amd/display: Expose HDR output metadata for supported connectors
[Why]
For userspace to send static HDR metadata to the display we need to
attach the property on the connector and send it to DC.
[How]
The property is attached to HDMI and DP connectors. Since the metadata
isn't actually available when creating the connector this isn't a
property we can dynamically support based on the extension block
being available or not.
When the HDR metadata is changed a modeset will be forced for now.
We need to switch from 8bpc to 10bpc in most cases anyway, and we want
to fully exit HDR mode when userspace gives us a NULL metadata, so this
isn't completely unnecessary.
The requirement can later be reduced to just entering and exiting HDR
or switching max bpc.

Some displays take some time to power up AUX CH once they are

as DPCD 2200h, etc.
[How]
Based on spec, receiver will monitor differential signal while in D3 and
AUX CH is in low power mode. When detected, it may allow up to
1 ms to power up AUX CH and reply.
If we read Sink power state D3, we should add 1 ms delay to satisfy

drm/amd/display: disable PSR/ABM before destroy DMCU struct
[Why]
1. DMCU is not running on some platform but driver still send ABM
command. It may cause assert due to DMCU is not alive.
2. To make sure PSR disable when driver disable
[How]
1. Add dmcu_is_running in ABM struct, driver can check this flag to
determine driver should send ABM command or not.

drm/amd/display: Ensure DRR triggers in BP
[Why]
In the previous implementation DRR event sometimes came
in during FP2 region which is a keep-out zone. This
would cause the frame not to latch until the next frame
which resulted in heavy flicker. To fix this we need
to make sure that it triggers in the BP.
[How]
1. Remove DRR programming during flip
2. Setup manual trigger for DRR event and trigger it
after surface programming is complete
