Subject: [GIT PULL] KVM/arm64 fixes for 6.13, part #2

Hi Paolo,

Another week, another batch of fixes. The most notable here is the MDCR_EL2
change from James, which addresses a rather stupid regression I introduced
in 6.13.

Please pull.

Thanks,
Oliver

  KVM: arm64: vgic-its: Add error handling in vgic_its_cache_translation (2024-12-03 16:22:10 -0800)

----------------------------------------------------------------
KVM/arm64 fixes for 6.13, part #2

 - 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
