On 64 bit architecture, we have plenty of vmalloc space
so that we can keep all the ptes mapped always
But on 32 but architecture, vmalloc space is limited and
hence we have to map/unmap ptes when required
Hence add new APIs for arch64 and call them if
IS_ENABLED(CONFIG_ARM64) is true

During the ELPG initialization routine, ELPG should be explicitly
disabled before we save the zbc table. This ensures that even if there
is a preemption from some other thread that calls ELPG enable/disable,
the ref counting will ensure that ELPG remains disabled.

After flash, kernel needs to reboot after first boot.
During reboot, devices is going to be shutdown including i2c.
But sometimes gpu driver trys to open gpu sysfs nodes and
unpowergate gpu at the same time. But i2c is already shutdown.
tegra_unpowergate_partition returns error in this case but
gk20a_tegra_unrailgate did not report the error so the error
is not handled. Return proper value in gk20a_tegra_unrailgate
to avoid this.

nvhost_get_syncpt_host_managed() creates syncpt name based on
platform_device pointer passed to it
Passing host1x's pointer to this API results in setting gk20a
syncpt names as "host1x_0" which is conflicting
Hence to restore this pass gk20a's device pointer
which gives syncpt names as "gk20a.0_0"

Add two fb flushes after bar1 bind. This should hang the thread instead
of whole system in case there is a BAR1 hang.

We poll completion of flush sequence by polling the broadcast
register. The polling should be done for a per-slice register
instead.
