[PATCH v2 0/3] KVM: Macrofy GPR swapping in assembly code

Posted by Paolo Bonzini 1 week, 2 days ago

A small change to Chang's patches from the APX series.
The main change is keeping __VCPU_REGS_* constants to avoid
relying on the ordering of constants in kvm_host.h, but I also
cleaned up the macros a bit to reduce the line code count
and clarify what is going on.

Paolo

v1->v2: remove unused r8d-r15d cases, clarify commit message,
	add comment, centralize .error usage in kvm_vcpu_regs.h
