Till GFX8 we can only enable PRT support globally, but with the next hardware
generation we can do this on a per page basis.
Keep the interface consistent by adding PRT mappings and enable
support globally on current hardware when the first mapping is made.
v2: disable PRT support delayed and on all error paths
v3: PRT and other permissions are mutal exclusive,
PRT mappings don't need a BO.
v4: update PRT mappings durign CS as well, make va_flags 64bit

Future hardware generations can handle PRT flags on a per page basis,
but current hardware can only turn it on globally.
Add the basic handling for both, a global callback to enable/disable
triggered by setting a per mapping flag.

Add the sysfs entries pp_gfx_power_profile and
pp_compute_power_profile which give user a way to set
power profile through parameters minimum sclk, minimum mclk,
activity threshold, up hysteresis and down hysteresis only
when the entry power_dpm_force_performance_level is in
default value "auto". It is read and write. Example:
echo 500 800 20 0 5 > /sys/class/drm/card0/device/pp_*_power_profile
cat /sys/class/drm/card0/device/pp_*_power_profile
500 800 20 0 5
Note: first parameter is sclk in MHz, second is mclk in MHz,
third is activity threshold in percentage, fourth is up hysteresis
in ms and fifth is down hysteresis in ms.
echo set > /sys/class/drm/card0/device/pp_*_power_profile
To set power profile state if it exists.
echo reset > /sys/class/drm/card0/device/pp_*_power_profile
To restore default state and clear previous setting.

this lock is used for sriov_gpu_reset, only get this mutex
can run into sriov_gpu_reset.
we have couple source triggers gpu_reset for SRIOV:
1) submit timedout and trigger reset voluntarily
2) invalid instruction detected by ENGINE and trigger reset voluntarily
2) hypervisor found world switch hang and trigger flr and notify guest to
do reset.
all need take care and we need a mutex to protect the consistency of

this is for SRIOV fix:
mqd soft init/fini will be invoked by sw_init to
allocate BO for compute MQD resource, instead of
original scheme that hw_init allocates MQD.
because if hw_init allocates MQD, then resume will
allocate MQD, and that lead to memory leak after
driver recovered from hang.

From commit 73dec95e6ba3 ("drm/i915: Emit to ringbuffer directly"),
copy_gma_to_hva() now returns copied data length instead of 0, so
need to change error return check for that.
Note: Looks this is caused by backmerge conflict resolving, so
4.11-rc4 is not impacted as commit 73dec95e6ba3 ("drm/i915: Emit to
ringbuffer directly") is not in 4.11. But need to fix this before I
can apply 4.12 stuff against drm-intel-next correctly.
