Commit Message

Sean Christopherson March 14, 2024, 11:26 p.m. UTC 
Move the base types unique to KVM selftests out of kvm_util.h and into a
new header, kvm_util_types.h.  This will allow kvm_util_arch.h, i.e. core
arch headers, to reference common types, e.g. vm_vaddr_t and vm_paddr_t.

No functional change intended.
