  Merge tag 'kvm-riscv-fixes-6.13-1' of https://github.com/kvm-riscv/linux into HEAD (2024-12-13 13:59:20 -0500)

----------------------------------------------------------------
ARM64:

* Fix confusion with implicitly-shifted MDCR_EL2 masks breaking
  SPE/TRBE initialization.

* Align nested page table walker with the intended memory attribute
  combining rules of the architecture.

* Prevent userspace from constraining the advertised ASID width,
  avoiding horrors of guest TLBIs not matching the intended context in
  hardware.

* Don't leak references on LPIs when insertion into the translation
  cache fails.

RISC-V:

* Replace csr_write() with csr_set() for HVIEN PMU overflow bit.

x86:

* Cache CPUID.0xD XSTATE offsets+sizes during module init - On Intel's
  Emerald Rapids CPUID costs hundreds of cycles and there are a lot of
  leaves under 0xD.  Getting rid of the CPUIDs during nested VM-Enter and
  VM-Exit is planned for the next release, for now just cache them: even
  on Skylake that is 40% faster.
