Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm fixes from Paolo Bonzini:
 "x86 guest:

   - Avoid false positive for check that only matters on AMD processors

  x86:

   - Give a hint when Win2016 might fail to boot due to XSAVES &&
     !XSAVEC configuration

   - Do not allow creating an in-kernel PIT unless an IOAPIC already
     exists

  RISC-V:

   - Allow ISA extensions that were enabled for bare metal in 6.8 (Zbc,
     scalar and vector crypto, Zfh[min], Zihintntl, Zvfh[min], Zfa)

  S390:

   - fix CC for successful PQAP instruction

   - fix a race when creating a shadow page"
