If acceleration is disabled, it does not make sense
to init gpuvm since nothing will use it. Moreover,
if radeon_vm_init() gets called it uses accel to try
and clear the pde tables, etc. which results in a bug.

Alex,
What is accel ?
Is there a situation where accel is disabled and HSA should work ?
e.g. headless mode ?
Not really.
Acceleration is disabled mostly because the user forgotten to install
the firmware or we have a rather big bug in the driver and can't get the
CP running.
In that case we still try to provide mode setting to get an error
message on the screen, but everything else won't work.
Regards,
Christian.
If so, we need gpuvm for local memory.
