Linus Torvalds 8c8d54116f platform-drivers-x86 for v6.13-5 
Fixes and new HW support:
 
  - amd/pmc: Match IRQ1 wakeup disable with the enable on i8042 side
 
  - intel: power-domains: Clearwater Forest support
 
  - intel/pmc: Skip SSRAM setup when no additional devices are present
 
  - ISST: Clearwater Forest support
 
 The following is an automated shortlog grouped by driver:
 
 amd/pmc:
  -  Only disable IRQ1 wakeup where i8042 actually enabled it
 
 intel/pmc:
  -  Fix ioremap() of bad address
 
 intel: power-domains:
  -  Add Clearwater Forest support
 
 ISST:
  -  Add Clearwater Forest to support list

Peter Zijlstra cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Scripted using

  git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file;
  do
    awk -i inplace '
      /^#define EXPORT_SYMBOL_NS/ {
        gsub(/__stringify\(ns\)/, "ns");
        print;
        next;

platform/x86/intel: TPMI domain id and CPU mapping 
Each TPMI power domain includes a group of CPUs. Several power
management settings in this case applicable to a group of CPUs.
There can be several power domains in a CPU package. So, provide
interfaces for:
- Get power domain id for a Linux CPU
- Get mask of Linux CPUs in a power domain

Hardware Punit uses different CPU numbering, which is not based on
APIC (Advanced Programmable Interrupt Controller) CPU numbering.
The Linux CPU numbering is based on APIC CPU numbering. Some PM features
like Intel Speed Select, the CPU core mask provided by the hardware is
based on the Punit CPU numbering. To use the core mask, this mask
needs to be converted to a Linux CPUs mask. So, provide interfaces for:
- Convert to a Linux CPU number from a Punit CPU number
- Convert to a Punit CPU number from a Linux CPU number

On each CPU online, MSR 0x54 is used to read the mapping and stores in
a per cpu array. Create a hash for faster searching of a Linux CPU number
from a Punit CPU number.
