Pull kvm fixes from Paolo Bonzini:
 "This is dominated by a couple large series for ARM and x86
  respectively, but apart from that things are calm.

  ARM:

   - Large set of FP/SVE fixes for pKVM, addressing the fallout from the
     per-CPU data rework and making sure that the host is not involved
     in the FP/SVE switching any more

   - Allow FEAT_BTI to be enabled with NV now that FEAT_PAUTH is
     completely supported

   - Fix for the respective priorities of Failed PAC, Illegal Execution
     state and Instruction Abort exceptions

   - Fix the handling of AArch32 instruction traps failing their
     condition code, which was broken by the introduction of
     ESR_EL2.ISS2

   - Allow vcpus running in AArch32 state to be restored in System mode

   - Fix AArch32 GPR restore that would lose the 64 bit state under some
     conditions

  RISC-V:

   - No need to use mask when hart-index-bits is 0

   - Fix incorrect reg_subtype labels in
     kvm_riscv_vcpu_set_reg_isa_ext()

  x86:

   - Fixes and debugging help for the #VE sanity check.

     Also disable it by default, even for CONFIG_DEBUG_KERNEL, because
     it was found to trigger spuriously (most likely a processor erratum
     as the exact symptoms vary by generation).

   - Avoid WARN() when two NMIs arrive simultaneously during an
     NMI-disabled situation (GIF=0 or interrupt shadow) when the
     processor supports virtual NMI.

     While generally KVM will not request an NMI window when virtual
     NMIs are supported, in this case it *does* have to single-step over
     the interrupt shadow or enable the STGI intercept, in order to
     deliver the latched second NMI.

   - Drop support for hand tuning APIC timer advancement from userspace.

     Since we have adaptive tuning, and it has proved to work well, drop
     the module parameter for manual configuration and with it a few
     stupid bugs that it had"
