Merge branch kvm-arm64/oslock into kvmarm-master/next

* kvm-arm64/oslock:
  : .
  : Debug OS-Lock emulation courtesy of Oliver Upton. From the cover letter:
  :
  : "KVM does not implement the debug architecture to the letter of the
  : specification. One such issue is the fact that KVM treats the OS Lock as
  : RAZ/WI, rather than emulating its behavior on hardware. This series adds
  : emulation support for the OS Lock to KVM. Emulation is warranted as the
  : OS Lock affects debug exceptions taken from all ELs, and is not limited
  : to only the context of the guest."

  KVM: arm64: Emulate the OS Lock
  KVM: arm64: Allow guest to set the OSLK bit
  KVM: arm64: Stash OSLSR_EL1 in the cpu context
  KVM: arm64: Correctly treat writes to OSLSR_EL1 as undefined
