There is a possibility of sharing process_private between two unrelated
processes due to PID wrapping. In kgsl_process_private_new(), instead
of checking numeric TGID, compare the unique pid pointer of the current
process with that of the existing processes in kgsl process list to
allow sharing of process_private data judiciously. Also, in all required
functions get TGID/PID of a process from its struct pid.

event->handle pointer can be used after free due to
the race condition between kgsl_sync_callback and
kgsl_sync_fence_async_cancel.
Protect the event->handle with a spinlock to
avoid concurrent access issues.

A context may be detached without submitting any commands
to GPU ringbuffer. This may cause us to wait on a timestamp
that will never be retired. So return immediately from
adreno_drawctxt_wait_rb() if context has not submitted any
commands to GPU ringbuffer.

Currently dispatcher accepts kgsl_cmdbatch object. This object
is a superset of all the types of objects dispatcher accepts.
Split kgsl_cmdbatch object to SYNC and IB/MARKER objects and
structure the code to make it easier for new type of objects
to be added to the dispatcher queue.

Rename all cmdbatch to drawobj. This forms a platform
for future changes where cmdbatch is split into different
types of drawobjs.

The format specifier %p can leak kernel addresses
while not valuing the kptr_restrict system settings.
Use %pK instead of %p, which evaluates whether
kptr_restrict is set.

Allow 5XX targets to preempt quickly from an atomic context. In
particular this allows quicker transition from a high priority
ringbuffer to a lower one without having to wait for the worker
to schedule.

Add a helper macro to convert an adreno_device pointer to a
struct kgsl_device pointer. This is mostly syntatic sugar
but it makes the code a bit cleaner and it abstracts a bit of
the ugliness away.
