This due to the fact that we do not free the "sg_table" itself while
freeing up the SG table and data pages. Fix this by freeing the sg_table
in tmc_free_sg_table().

With the flat mode, we only attempt to allocate large memory if there is an IOMMU
connected to the ETR. If the allocation fails, we always have a fallback path
and return an error if nothing else worked. So, suppress the warning for flat
mode allocations.

coresight: tmc: Explicit type conversions to prevent integer overflow

Perf cs_etm session executed unexpectedly when AUX buffer > 1G.

perf record -C 0 -m ,2G -e cs_etm// -- <workload>
[ perf record: Captured and wrote 2.615 MB perf.data ]

Perf only collect about 2M perf data rather than 2G. This is becasuse
the operation, "nr_pages << PAGE_SHIFT", in coresight tmc driver, will
overflow when nr_pages >= 0x80000(correspond to 1G AUX buffer). The
overflow cause buffer allocation to fail, and TMC driver will alloc
minimal buffer size(1M). You can just get about 2M perf data(1M AUX
buffer + perf data header) at least.

Explicit convert nr_pages to 64 bit to avoid overflow.

Pull irqchip updates from Marc Zyngier:

- A number of Loogson/Loogarch fixes

- Allow the core code to retrigger an interrupt that has
fired while the same interrupt is being handled on another
CPU, papering over a GICv3 architecture issue

- Work around an integration problem on ASR8601, where the CPU
numbering isn't representable in the GIC implementation...

- Add some missing interrupt to the STM32 irqchip

- A bunch of warning squashing triggered by W=1 builds

coresight: Updates for v6.5

CoreSight and hwtracing subsystem updates for v6.5 includes:

- Fixes to the CTI module reference leaks. This involves,
redesign of how the helper devices are tracked and CTI
devices have been converted to helper devices.
- Fix removal of the trctraceidr file from sysfs for ETMs.
- Match all ETMv4 instances based on the ETMv4 architected
registers and the CoreSight Component ID (CID), than having
to add individual PIDs for CPUs.
- Add support for Dummy CoreSight source and sink drivers.
- Add James Clark as Reviewer for the CoreSight kernel drivers
- Fixes to HiSilicon PCIe Tune and Trace Device driver
