Revert "drm/amd/display: Enable fast plane updates when state->allow_modeset = true"
This reverts commit
ebc8c6f18322ad54275997a888ca1731d74b711f.
There are still missing corner cases with cursor interaction and these
fast plane updates on Picasso and Raven2 leading to endless PSTATE
warnings for typical desktop usage depending on the userspace.
This change should be reverted until these issues have been resolved.

drm/amd/display: Fix null-deref on vega20 with xgmi
[Why]
After clkmgr rework it gets initialized after resource pool.
The clkmgr is used in resource pool init for xgmi path.
That causes driver crash on Vega20 with xgmi due to NULL deref.
[How]
Move xgmi compensation code to dce121_clk_mgr_construct()
That also allows to make dce121_clock_patch_xgmi_ss_info()

Revert "drm/amdkfd: Fix sdma queue allocate race condition"
This reverts commit
f77dac6cd62e5d4bcadd740620af1218bfb54cc6.
This fix is not proper. allocate_mqd can't be moved before
allocate_sdma_queue as it depends on q->properties->sdma_id
set in later.

drm/amdkfd: Separate mqd allocation and initialization
Introduce a new mqd allocation interface and split the original
init_mqd function into two functions: allocate_mqd and init_mqd.
Also renamed uninit_mqd to free_mqd. This is preparation work to
fix a circular lock dependency.

drm/amdgpu: use new HMM APIs and helpers
HMM provides new APIs and helps in kernel 5.2-rc1 to simplify driver
path. The old hmm APIs are deprecated and will be removed in future.
Below are changes in driver:
1. Change hmm_vma_fault to hmm_range_register and hmm_range_fault which
supports range with multiple vmas, remove the multiple vmas handle path
and data structure.
2. Change hmm_vma_range_done to hmm_range_unregister.
3. Use default flags to avoid pre-fill pfn arrays.
4. Use new hmm_device_ helpers.

drm/amdgpu: Fix bounds checking in amdgpu_ras_is_supported()
The "block" variable can be set by the user through debugfs, so it can
be quite large which leads to shift wrapping here. This means we report
a "block" as supported when it's not, and that leads to array overflows
later on.
This bug is not really a security issue in real life, because debugfs is
generally root only.

drm/amd/display: set link->dongle_max_pix_clk to 0 on a disconnect
[Why]
Found issue in EDID Emulation where if we connect a display using
a passive HDMI-DP dongle, disconnect it and then try to emulate
a display using DP, we could not see 4K modes. This was because
on a disconnect, dongle_max_pix_clk was still set so when we
emulate using DP, in dc_link_validate_mode_timing(), it would
think we were still using a dongle and limit the modes we support.
[How]
In dc_link_detect(), set dongle_max_pix_clk to 0 when we detect
a hotplug out ( if new_connection_type = dc_connection_none ).
