[Xen-devel] [PATCH 1 of 6] xen: fix build when 'perfc=y'

Which was failing with this:

 viridian.c: In function âwrmsr_viridian_regsâ:
 viridian.c:254:1: error: âPERFC_mshv_wrmsr_apic_msrâ undeclared (first use in 
this function)
 viridian.c:254:1: note: each undeclared identifier is reported only once for 
each function it appears in
 viridian.c: In function ârdmsr_viridian_regsâ:
 viridian.c:305:1: error: âPERFC_mshv_rdmsr_apic_msrâ undeclared (first use in 
this function)

as a consequence of 17b754cab7b0 using but not defining
the counters.
