x86, perf events: Check if we have APIC enabled
Ralf Hildebrandt reported this boot warning:
| Running a vanilla 2.6.32 as Xen DomU, I'm getting:
|
| [ 0.000999] CPU: Physical Processor ID: 0
| [ 0.000999] CPU: Processor Core ID: 1
| [ 0.000999] Performance Events: AMD PMU driver.
| [ 0.000999] ------------[ cut here ]------------
| [ 0.000999] WARNING: at arch/x86/kernel/apic/apic.c:249 native_apic_write_dummy
So we need to check if APIC functionality is available, and
not just in the P6 driver but elsewhere as well.
