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.

[What]
readptr read always returns zero, since most likely
these blocks are either power or clock gated.
[How]
fetch rptr after amdgpu_ring_alloc() which informs
the power management code that the block is about to be
used and hence the gating is turned off.

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.

[Why]
It's non trivial to configure or specify an ABM reduction level for
userspace outside of X. There is also no method to specify the default
ABM value at boot time.
A parameter should be added to configure this.
[How]
Expose a module parameter that can specify the default ABM level to
use for eDP connectors on DC enabled hardware that loads the DMCU
firmware.
The default is still disabled (0), but levels can range from 1-4. Levels
control how much the backlight can be reduced, with being the least
amount of reduction and four being the most reduction.
