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.

There are some subtle differences between revisions of GPUs
that are not reflected in the GPU ID value. Return the raw
chipid (derived from the hardware) along with the GPU ID
when queried.

The code seeking out the failing frame for a hang got confused if
the CP read and write pointers were equal resulting in missing
IBs.

Use a iterator to cleanup how snapshot GPU objects are printed.
This removes a ton of ugly math, and allows us to do subtle
silly things like add padding at the end of a non dword
aligned object.

Enhance the logic that checks to see if the CP_RPTR is stuck
mid packet. Ensure that when we do packet counting that we
use real type3 packets instead of regular data pretending to
be a type3 packet.

Currently we just check the most significant two bits of a dword
in the ringbuffer or IB are set to decide if the data is a type3
packet header. This has proven to be problematic, as it turns out
that the top two bits are often set in nominal data. Enhance
the type3 packet check to verify that various reserved bits in
the dword are 0 as expected.

User side drivers are starting to use more indirect buffers
for CP_LOAD_STATE, so expand the snapshot to support grabbing
all of the possible combinations.

If there is a failure in drawctxt create, then the KGSL core will call
drawctxt destroy to free the memory. If the failure happened soon
enough, there might not a drawctxt to free.

Conditional interrupts were not getting fired at the correct time when
using per context timestamps. When a context was waiting on a timestamp,
the interrupt was being fired on the global timestamp rather than the per
context timestamp. Now the interrupt is fired on the per context
timestamp.

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.

Get the current pagetable being used by the GPU by reading the
pagetable register during iommu pagefault and use that base
address to get the pid of the process corresponding to the
pagetable. Earlier we were using the pagetable address that the
IOMMU driver thinks is presently set for the GPU which may not
always be the case because we change the pagetable used by the
GPU without informing the IOMMU driver.
