msm: mdss: fix possible out-of-bounds and overflow issue in mdp debugfs
There are few cases where the count argument passed by the user
space is not validated, which can potentially lead to out of bounds
or overflow issues. In some cases, kernel might copy more data than
what is requested. Add necessary checks to avoid such cases.

If the ioctl syncsource_destroy is accessed by parallel
threads, where the spinlock is acquired by threads after
getting syncsource, then the simultaneous processes try
to remove the already destroyed syncsource->refcount by
the first thread that acquires this spinlock. This leads
to race condition while removing syncsource->idr.

acquire spinlock before we get the syncsource in

iommu: Add {enable,disable}_config_clocks ops
There are certain use cases where it might be necessary to leave the
IOMMU's configuration clocks on. This might happen in places where an
IOMMU's clocks might not be known. A good example of this would be a
test library that needs to be able to do TLB invalidation from atomic
context. It would need to enable clocks up front (outside of atomic
context) and leave them on for the duration of the test.
Add some ops for enabling and disabling configuration clocks.

iommu/arm-smmu: Implement the .tlbi_domain op
The upcoming "fast" DMA mapper will need to take control of TLB
invalidation. Doing so allows us to perform fewer TLB invalidation
operations since the DMA mapper layer has more knowledge about when
"stale" TLB entries might actually become a problem, so it can do TLB
invalidation much less frequently. Implement the tlbi_domain op for
this purpose.

iommu: Add tlbi_domain op
Some higher-level DMA mappers might be able to squeeze out more

by individual IOMMU drivers.

iommu/io-pgtable: Add fast page table mapper for ARMv8L
Certain use cases require performance that can't be achieved with the
general-purpose SMMU page table code. By limiting ourselves to 4K page
mappings (no block mappings) and pre-populating the first and second
levels of the page tables up front, we can eliminate a lot of the work
needed for page table mapping and unmapping.
Add a performance-tuned io-pgtable implementation for ARMv8L page tables
that only supports 4K page mappings. Any size can be mapped, but only
4K page mappings will be installed in the page tables.

iommu/arm-smmu: Implement .get_pgsize_bitmap for domain
Currently we restrict the pgsize_bitmap for the entire SMMU every time
we allocate some new page tables. However, certain io-pgtable
implementations might wish to restrict the formats beyond the
restrictions of the SMMU itself, which forces all domains on that SMMU
to the same pgsize_bitmap, even if the other domains would prefer to use
a more permissive page table format. Besides that, some SMMUs in the
system might have different supported page sizes at the hardware level,
so applying those to everyone else is wrong.
Fix these issues by implementing the new .get_pgsize_bitmap IOMMU op.
