Pull kvm fixes from Paolo Bonzini:
 "ARM64:

   - Fix the guest view of the ID registers, making the relevant fields
     writable from userspace (affecting ID_AA64DFR0_EL1 and
     ID_AA64PFR1_EL1)

   - Correcly expose S1PIE to guests, fixing a regression introduced in
     6.12-rc1 with the S1POE support

   - Fix the recycling of stage-2 shadow MMUs by tracking the context
     (are we allowed to block or not) as well as the recycling state

   - Address a couple of issues with the vgic when userspace
     misconfigures the emulation, resulting in various splats. Headaches

   - Stop wasting space in the HYP idmap, as we are dangerously close to
     the 4kB limit, and this has already exploded in -next

   - Fix another race in vgic_init()

   - Fix a UBSAN error when faking the cache topology with MTE enabled

  RISCV:

   - RISCV: KVM: use raw_spinlock for critical section in imsic

  x86:

   - A bandaid for lack of XCR0 setup in selftests, which causes trouble
     if the compiler is configured to have x86-64-v3 (with AVX) as the
     default ISA. Proper XCR0 setup will come in the next merge window.

   - Fix an issue where KVM would not ignore low bits of the nested CR3
     and potentially leak up to 31 bytes out of the guest memory's
     bounds

   - Fix case in which an out-of-date cached value for the segments
     could by returned by KVM_GET_SREGS.

   - More cleanups for KVM_X86_QUIRK_SLOT_ZAP_ALL

   - Override MTRR state for KVM confidential guests, making it WB by
     default as is already the case for Hyper-V guests.

  Generic:

   - Remove a couple of unused functions"
