From: Arnd Bergmann <arnd@xxxxxxxx>
There are hundreds of warnings in a W=2 build about a local
variable shadowing the global 'apic' definition:
arch/x86/kvm/lapic.h:149:65: warning: declaration of 'apic' shadows a global declaration [-Wshadow]
Avoid this by renaming the local in the kvm/lapic.h header
Fixes: c48f14966cc4 ("KVM: inline kvm_apic_present() and kvm_lapic_enabled()")
Fixes: c8d46cf06dc2 ("x86: rename 'genapic' to 'apic'")
