wait_for_completion_interruptible() returns ERESTARTSYS when
the device goes to low power mode.
The SPU subsystem is shutdown on deep low power mode,
so the interrupted operation is not recoverable.

The CMA performance optimizations depend on QGKI, which
prevents them from being enabled on configurations that don't
have a notion of GKI and QGKI. Thus, remove this dependency.
This shouldn't cause any problems with the ABI surface with
respect to GKI targets as the configs still have to be enabled
explicitly anyway.

The SELinux policy on Android doesn't provide the kernel-space
with CAP_SYS_ADMIN capability. The perf-core checks for this
capability before giving access to the callers to read the PMU
counters. Hence, when the kernel drivers try to gain access
to the PMU (via perf_event_create_kernel_counter()), it fails
with -EACCES.
To get past this, add another condition to check if the request
is coming from kernel-space or user-space. If kernel-space,
don't check for the capability any further and move on.

The interconnect graphs can be difficult to understand and the current
"interconnect_summary" file doesn't even display links in any way.
Add a new "interconnect_graph" file to debugfs in the graphviz "dot"
format which describes interconnect providers, nodes and links.
The file is human-readable and can be visualized by piping through
graphviz. Example:
ssh $TARGET cat /sys/kernel/debug/interconnect/interconnect_graph \
| dot -Tsvg > interconnect_graph.svg

Certain SMMU implementations depend on implementation specific
settings to ensure that translations for a group of SMMU masters
work properly, so add a function to determine if a master belongs
in a particular IOMMU group based on implementation defined
settings.
Also, wire up the QSMMUV500 implementation of this hook, leaving
the arm_smmu_arch_ops structure completely unused. Since it has
been superseded by the implementation framework, remove the
remaining support for it.

Certain SMMU implementations may need to follow certain
procedures prior to having their devices removed, so
add support for implementation specific removals.
Also, migrate the QSMMUV500 device removal function to utilize
the newly added implementation specific removal hook. This makes
it so that there are no users of the device_remove() hook in the
arm_smmu_arch_ops structure, so remove it.

translation for verification purpose, and wire up the QSMMUV500
implementations of these hooks. In doing so, there are no
users of the iova_to_phys_hard() and tlb_sync_timeout() hooks

Some SMMU implementations, such as the QSMMUV500 model, may
need to program a specific context bank, in addition to the
initial context bank programming. Thus, add support for
implementation specific context bank initialization, and
migrate the QSMMUV500 context bank initialization to use
the new hook.
Consequently, as there are no current users of the
arm_smmu_arch_init_context_bank() hook, remove it.

Rework the QSMMUV500 initialization sequence, such that the
QSMMUV500 implementation initialization uses the existing
SMMU implementation architecture.
This means ensuring that all of the implementation specific
data structures are allocated as part of the initialization,
as well as ensuring that all of the TBUs have probed. Also,
move the logic for hardware version detection to the QSMMUV500
configuration probe function.
Consequently, there are now no users of the arm_smmu_arch_init()
and arm_smmu_arch_device_reset() hooks, so remove them.

All of the implementation details related to the QSMMUV500 model
of the SMMU-V2 architecture currently reside in arm-smmu.c.
This clashes with the current ARM SMMU SW architecture, as
arm-smmu.c is meant to house architecture specific details,
and arm-smmu-[$VENDOR].c is meant to house vendor specific
implementation details about those architectures.
To prepare to move to comply with this architecture, migrate
the QSMMUV500 related logic to arm-smmu-qcom.c, as well as
export any shared data structures. This patch should not
introduce any functional changes.
