base: genlock: protect kref counting with spinlock

A race condition exists where the attach may not kref_get
before the kref_put finished. The genlock_file_lock was
originally added to protect against this case however it
was not protecting the kref.

base: genlock: add magic to protect attach from non-genlock file

It is possible for user space to attempt to attach a valid fd that
does not correspond to a genlock file. This change adds a magic to
the kernel private data that is used for validation.

msm: kgsl: Only return tlb flush flag if bit is set for given device

We should only return the tlb flush flag if the bit corresponding
to the given device is set in the tlb flags. Earlier we were returning
the flush flag always if the tlb flags had the flush bit set for any
device.

kgsl_core_exit() should not call kgsl_sharedmem_uninit_sysfs() and
device_unregister() if those resources have not been allocated.
We check this by seeing if kgsl_driver.virtdev has been
populated or not.

msm: kgsl: Add draw workaround commands after every 50 context switches

We need to add a draw workaround command sequence after every 50 context
switches if the gmem has not been saved in those 50 switches. This
workaround is required to prevent the GPU from deadlocking. Since gmem
save commands have draw calls in them we only need to execute this
workaround if the gmem has not been saved. The number 50 was chosen
empirically.

msm: kgsl: Issue packet to set shader bases on A20x/220 GPU

When GMEM save is not performed, the events to reuse shader space
can get dropped. This make the CP block to wait indefinitely
causing a hang. To unblock this, issue a packet to set shader bases.
This applies only to A20x/220 GPU.
