Currently, Ion registers all debugfs entries for clients
via pid. If there are multiple kernel clients, this means
the debugfs entry only gets created for the first one. Fix
this by creating debugfs entries by name always. When
creating user clients, specify the name via the pid.

Because the IBs used for context switching are not allocated
by userspace, a separate search is needed to find them
in adreno_find_region.

Some hangs are fooling the postmortem dump code into
running off the end of a buffer. Fix this by making
its bounds check logic work better by reusing the
logic from kgsl_find_region().

When mmap is called to remove a mapping, the mmap code
takes care of removing all the entries so it isn't
necessary to call unmap versions. However, there may be
cases where heaps need to do other buffer clean up when
a userspace buffer is unmapped. Add an unmap_user function
to the ion heap ops. This callback needs to happen in
vma_close, so move the decrementing of the overall user map
call back as well.

Ion allows multiple mmaps of the same buffers. This means that
incrementing the usermap count in mmap and decrementing it in
release is not sufficient as release will only ever be called
once. Fix this by only doing the reference count change in the
vma_open and close which are called whenever mmap is called.

The tools that process cff dumps expect a linear
memory region, but the start address of that region can
be configured. As long as there is only a single
pagetable (so that there aren't duplicate virtual
addresses in the dump), dumps captured with the
mmu on are easier to deal with than reconfiguring
to turn the mmu off.

Issue an empty draw call to avoid possible hangs due to
repeated idles without intervening draw calls.
On adreno 225 the PC block has a cache that is only
flushed on draw calls and repeated idles can make it
overflow if there are not intervening draw calls.
The gmem save path contains draw calls so this workaround
isn't needed there.

Cache flushing takes the mmap semaphore to validate the
address range. This can cause a deadlock in the following
scenario with two threads in the same client:
Thread 1 Thread 2
(cache operation) (mmap)
-----------------------------------------
lock(client_lock)
down_write(mmap_semaphore)
down_read(mmap_semaphore)
lock(client_lock)
Fix this by doing the check for the address range before
taking the client lock. This is independent of Ion so there
is no need to have this lock locked.
