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@arndb.de> > --- Applied, thanks.

The rework of the posted interrupt handling broke building without support for the local APIC: ERROR: "boot_cpu_physical_apicid" [arch/x86/kvm/kvm-intel.ko] undefined! That configuration is probably not particularly useful anyway, so we can avoid the randconfig failures by adding a Kconfig dependency.
