On some systems the nominal_perf value retrieved via CPPC is just
a constant and fetching it doesn't require accessing any registers,
so if it is the only CPPC capability that's needed, it is wasteful
to run cppc_get_perf_caps() in order to get just that value alone,
especially when this is done for CPUs other than the one running
the code.
For this reason, introduce cppc_get_nominal_perf() allowing
nominal_perf to be obtained individually, by generalizing the
existing cppc_get_desired_perf() (and renaming it) so it can be
used to retrieve any specific CPPC capability value.
While at it, clean up the cppc_get_desired_perf() kerneldoc comment
a bit.

The memory attributes attached to memory regions depend on architecture
specific mappings.
For some memory regions, the attributes specified by firmware (eg
uncached) are not sufficient to determine how a memory region should be
mapped by an OS (for instance a region that is define as uncached in
firmware can be mapped as Normal or Device memory on arm64) and
therefore the OS must be given control on how to map the region to match
the expected mapping behaviour (eg if a mapping is requested with memory
semantics, it must allow unaligned accesses).
Rework acpi_os_map_memory() and acpi_os_ioremap() back-end to split
them into two separate code paths:
acpi_os_memmap() -> memory semantics
acpi_os_ioremap() -> MMIO semantics
The split allows the architectural implementation back-ends to detect
the default memory attributes required by the mapping in question
(ie the mapping API defines the semantics memory vs MMIO) and map the
memory accordingly.

Commit 71f6428332 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer
that was possibly NULL. That fails miserably, because that helper
inline function is not set up to handle that case.
Just make acpi_dev_put() silently accept a NULL pointer, rather than
calling down to put_device() with an invalid offset off that NULL
pointer.

Currently it's possible to iterate over the dangling pointer in case the device
suddenly disappears. This may happen becase callers put it at the end of a loop.
Instead, let's move that call inside acpi_dev_get_next_match_dev().

a dependence on other ACPI devices as opposed to the OpRegions that the
specification intends.
We need to be able to find those devices "from" the dependee, so add

the dependent ACPI device.

The acpi_walk_dep_device_list() function is not as generic as its

dependent device of the input.
Extend it to accept a callback which can be applied to all the
dependencies in acpi_dep_list.
Replace all existing calls to the function with calls to a wrapper,
passing a callback that applies the same dependency reduction.

ACPICA commit b5e6bcf69dbb9877481992d5ce86008cfb94f5b8
SVKL (Storage Volume Key Location Table) is used by BIOS/Firmware
to share storage volume encryption key's with OS. It will be used
by userspace to decrypt and mount encrypted drives.
So add SVKL table signature and add it to known signatures array
support SVKL.
You can find details about the SVKL table in TDX specfication
titled "Guest-Host-Communication Interface (GHCI) for Intel
Trust Domain Extensions (Intel® TDX)", sec 4.4 and in ACPI
specification r6.4, sec 5.2.6.

The macro requires to call acpi_dev_put() on each iteration.
Due to this it doesn't tolerate sudden disappearence of the devices.
Document all these nuances to prevent users blindly call it without
understanding the possible issues.
While at it, add the note to the acpi_dev_get_next_match_dev() and
advertise acpi_dev_put() instead of put_device() in the whole family
of the helper functions.

ACPICA commit 8710a708faed728ea2672b8da842b2e9af1cf5bd
IORT revision E.b (ARM DEN 0049E.b) contains a few additions like,
-Added an identifier field in the node descriptors to aid table
cross-referencing.
-Introduced the Reserved Memory Range(RMR) node. This is used
to describe memory ranges that are used by endpoints and require
a unity mapping in SMMU.
-Introduced a flag in the RC node to express support for PRI.
-Added a flag in the RC node to declare support for PASID forward
information.
Please note that IORT Rev E and E.a have known issues and are not
supported.
