Linus Torvalds 493804a689 RISC-V:

- ONE_REG interface to enable/disable SBI extensions
 - Zbb extension for Guest/VM
 - AIA CSR virtualization
 
 x86:
 - Fix a long-standing TDP MMU flaw, where unloading roots on a vCPU can
   result in the root being freed even though the root is completely valid
   and can be reused as-is (with a TLB flush).
 
 s390:
 - A couple bugfixes.

Pull more kvm updates from Paolo Bonzini:
 "This includes the 6.4 changes for RISC-V, and a few bugfix patches for
  other architectures. For x86, this closes a longstanding performance
  issue in the newer and (usually) more scalable page table management
  code.
