* gpu: nvgpu: Remove redundant locked variableArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | Queue locked variable holds entirely redundant information about the queue status and having the variable causes a race between lock() and unlock() functions. This patch removes the locked variable.

| | | | | | | | | | | | | | | | | | | 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 Bug 1443071 Change-Id: I091d1d6a3883a1b158c5c88baeeff1882ea1fc8b Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/387642 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* video: tegra: host: gk20a: reorder init save zbcPrashant Malani2015-03-18
| | | | | | | | | | | | | | | 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.

* gpu: nvgpu: handle error when gpu failed to unpowergateKerwin Wan2015-03-18
| | | | | | | | | | | | | | | | | | | | | 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.
