[Xen-devel] Re: [PATCH 2 of 7] x86/pvops: add a paravirt_ident functions

Then use that everywhere rather than these defines?
Hm, also I don't think that will work because paravirt_ident_32|64
return different types. The compiler might promote paravirt_ident_32 to
returning a 64-bit number, which would be a bit disastrous.
