I like "register" though.

Isn't it possible that e.g. get_vmx_mem_address() will do kvm_register_read()
for a RIP-relative address?  One could RIP isn't a pure GPR, but it's also not
something entirely different either.

But then later patches use for Extended GPRs, so the name becomes a lie.  I also
don't like unnecessary use of acronyms, even though GPR is ubiquitous in x86.
Everyone looking at KVM knows what a register is, but only x86 folks will know
what GPR is.
