From: Mark Rustad <mark.d.rustad@xxxxxxxxx>
Change the name of formal parameters in some static inlines from
apic, which shadows a global of the same name, to apicid. Also
change the formal parameter name on some trace functions for the
same reason. This eliminates many thousands of shadow warnings
in my W=2 kernel build.
