msm: kgsl: Don't do intensive memory recovery when allocating big pages

We don't want to incur too much overhead when allocating big pages
so don't attempt to retry, perform reclaim, or run memory compaction
on high-order allocations.

msm: kgsl: Insert kgsl idle for iommu-v1 when pagetables are changed.

An idle is needed for iommu-v1 before programming both tlb registers
and the pagetable register. Without this idle faults are observed on
2D core because a process uses another processes pagetable.

msm: kgsl: Add NULL check for next_event hook

KGSL driver needs to check that the function pointer
is not NULL before calling the hook. next_event
is an optional function not implemented by the 2d
core. This fix ensures that optional and unimplemented
function will not invoked by the driver.

msm: kgsl: Don't consider active count if not in active state

Don't consider active_cnt variable if not already in ACTIVE state.
The active count variable does not necessarily exactly indicate the
number of open handles to GPU for switching power state. Hence,
only wait for active count to reach zero before switching to SUSPEND
state if, the current state is ACTIVE.

gpu: msm: Allow retries for 0 order allocation

When allocating order 0 pages we allow the allocator to retry
the allocation to ensure we can take advantage of pages that
are being reclaimed. This will help avoid unnecessary out
of memory errors from kgsl clients.

gpu: ion: Do fallback when allocating large sizes

The preferred allocation of memory for kernel data structures in
ION is to use kmalloc. This is mainly for performance reasons. However,
we are not guaranteed to be able to allocate large sizes. So to keep
the code performing well and at the same time allow for larger allocations,
implement a fallback mechanism for allocation of memory for ION kernel data
structures.

msm: kgsl: generate descriptive names for kgsl-timeline

Generate names for kgsl-timelines using the following format:
<device>-<thread name>(<tid>)-<proc name>(<pid>)-<context id>

This makes it possible to identify the context of a timeline in the
sync dump, which makes it much easier to identify which context has
a GPU timeout.
