The iommu_map_sgtable() function returns ssize_t and negative error
codes but it's declared as size_t instead. I think that static checkers
would have complained if this caused a bug, but even though it doesn't
cause a bug, it's definitely worth fixing.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and
fixed manually.

The original debugfs only dumps all page tables without pasid. With
pasid supported, the page table with pasid also needs to be dumped.
This patch supports dumping a specified page table in legacy mode or
scalable mode with or without a specified pasid.
For legacy mode, according to bus number and DEVFN, traverse the root
table and context table to get the pointer of page table in the
context table entry, then dump the specified page table.
For scalable mode, according to bus number, DEVFN and pasid, traverse
the root table, context table, pasid directory and pasid table to get
the pointer of page table in the pasid table entry, then dump the
specified page table..
Examples are as follows:
1) Dump the page table of device "0000:00:1f.0" that only supports
legacy mode.
$ sudo cat
/sys/kernel/debug/iommu/intel/0000:00:1f.0/domain_translation_struct
2) Dump the page table of device "0000:00:0a.0" with PASID "1" that
supports scalable mode.
$ sudo cat
/sys/kernel/debug/iommu/intel/0000:00:0a.0/1/domain_translation_struct

Add a debugfs directory per pair of {device, pasid} if the mappings of
its page table are created and destroyed by the iommu_map/unmap()
interfaces. i.e. /sys/kernel/debug/iommu/intel/<device source id>/<pasid>.
Create a debugfs file in the directory for users to dump the page
table corresponding to {device, pasid}. e.g.
/sys/kernel/debug/iommu/intel/0000:00:02.0/1/domain_translation_struct.
For the default domain without pasid, it creates a debugfs file in the
debugfs device directory for users to dump its page table. e.g.
/sys/kernel/debug/iommu/intel/0000:00:02.0/domain_translation_struct.
When setting a domain to a PASID of device, create a debugfs file in
the pasid debugfs directory for users to dump the page table of the
specified pasid. Remove the debugfs device directory of the device
when releasing a device. e.g.
/sys/kernel/debug/iommu/intel/0000:00:01.0

A large amount of time was spent in the refcount.

no need to take references for that one. That is exactly what the
critical section helpers do, make use of them.
New perf output:

The result is a throughput improvement of around 20% across the board

Improve the function ata_dev_power_set_active() by having it do nothing
for a disk that is already in the active power state. To do that,
introduce the function ata_dev_power_is_active() to test the current
power state of the disk and return true if the disk is in the PM0:
active or PM1: idle state (0xff value for the count field of the CHECK
POWER MODE command output).
To preserve the existing behavior, if the CHECK POWER MODE command
issued in ata_dev_power_is_active() fails, the drive is assumed to be in
standby mode and false is returned.
With this change, issuing the VERIFY command to access the disk media to
spin it up becomes unnecessary most of the time during system resume as
the port reset done by libata-eh on resume often result in the drive to
spin-up (this behavior is not clearly defined by the ACS specifications
and may thus vary between disk models).

debugfs_create_dir() function returns an error value embedded in
the pointer (PTR_ERR). Evaluate the return value using IS_ERR
rather than checking for NULL.

In the previous code, the 'mds' and 'nrhandler' variables were not
utilized in the codebase. Additionally, there was a potential NULL
pointer dereference and memory leak due to improper handling of memory
reallocation failure.
This patch removes the unused 'mds' and 'nrhandler' variables along with
the associated code, addressing the unused variable issue, NULL pointer
dereference issue and the memory leak issue.

Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present for any node.
Add unevaluatedProperties as needed, and then add any missing properties
flagged by the addition.

The upcoming mt7988 has different temperature coefficients so we
cannot use constants in the functions lvts_golden_temp_init,
lvts_golden_temp_init and lvts_raw_to_temp anymore.
Add a field in the lvts_ctrl pointing to the lvts_data which now
contains the soc-specific temperature coefficents.
To make the code better readable, rename static int coeff_b to
golden_temp_offset, COEFF_A to temp_factor and COEFF_B to temp_offset.
