Inelegant, sure, but it can work :-) It works, there are already functions in the kernel that use these macros more than once.

Yes, that's what we're doing here. Only KVM uses msr_s/msr_s directly, everything else uses the (read|write)_sysreg_s wrappers instead, which means the DEFINE/UNDEFINE macros are only needed in few places.
