Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull KVM/arm64 updates from Will Deacon:
 "New features:

   - Support for non-protected guest in protected mode, achieving near
     feature parity with the non-protected mode

   - Support for the EL2 timers as part of the ongoing NV support

   - Allow control of hardware tracing for nVHE/hVHE

  Improvements, fixes and cleanups:

   - Massive cleanup of the debug infrastructure, making it a bit less
     awkward and definitely easier to maintain. This should pave the way
     for further optimisations

   - Complete rewrite of pKVM's fixed-feature infrastructure, aligning
     it with the rest of KVM and making the code easier to follow

   - Large simplification of pKVM's memory protection infrastructure

   - Better handling of RES0/RES1 fields for memory-backed system
     registers

   - Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer
     from a pretty nasty timer bug

   - Small collection of cleanups and low-impact fixes"
