msm: msm_fb: Do not use ION_IOMMU_UNMAP_DELAYED flag.

Since iommu buffers will be unmapped after two newer commits
had passed, there is no need to request iommu driver to further
delay unmapping an iommu buffer.

kref: Implement kref_get_unless_zero v3

This function is intended to simplify locking around refcounting for
objects that can be looked up from a lookup structure, and which are
removed from that lookup structure in the object destructor.
Operations on such objects require at least a read lock around
lookup + kref_get, and a write lock around kref_put + remove from lookup
structure. Furthermore, RCU implementations become extremely tricky.
With a lookup followed by a kref_get_unless_zero *with return value check*
locking in the kref_put path can be deferred to the actual removal from
the lookup structure and RCU lookups become trivial.

v2: Formatting fixes.
v3: Invert the return value.

msm: kgsl: Add separate GPU shader memory mapping

Add separate kernel memory mapping for GPU shader memory.
Previously, both the register and the shader memory were mapped
as one entity, with the mapping length being equal to combined
size of register memory and shader memory. Now, we separate the
shader memory mapping to help in cases of GPU devices where the
shader and register memory may not be adjacent. This helps to
dump the shader memory in the postmortem snapshot. By having a
separate mapping for shader memory, the snapshot dump routine
simply reads in the shader memory range specified and dumps.

msm: Fix mem leak when using per-process pages

When GPU is using per process page tables the code creates
a new page table (domain) for every process. There is also
some associated structures allocated to keep track of each
domain. However, when cleaning up the memory used for a page
table only the domain is freed and not the associated structures.

Add a function to allow a client to properly unregister a domain
which will free all the memory associated with a domain.
Call the unregister function from kgsl driver code.

iommu/core: pass a user-provided token to fault handlers

Sometimes a single IOMMU user may have to deal with several
different IOMMU devices (e.g. remoteproc).

When an IOMMU fault happens, such users have to regain their
context in order to deal with the fault.

Users can't use the private fields of neither the iommu_domain nor
the IOMMU device, because those are already used by the IOMMU core
and low level driver (respectively).

This patch just simply allows users to pass a private token (most
notably their own context pointer) to iommu_set_fault_handler(),
and then makes sure it is provided back to the users whenever
an IOMMU fault happens.

The patch also adopts remoteproc to the new fault handling
interface, but the real functionality using this (recovery of
remote processors) will only be added later in a subsequent patch
set.
