Yeah, and we can follow up by removing few ifdefs. > Fixes: 8b306e2f3c41 ("KVM: VMX: avoid double list add with VT-d posted interrupts") The offending cpu_physical_id() was there even before, so it is probably the change of condition in pi_post_block that violated dead code detection. > Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> > --- Applied, thanks.
