So the msrpm bitmap changes dynamically for each vcpu? Great, make it
fully dynamic then, changing the vcpu->arch.msrpm only from within its
vcpu context. No need for atomic ops.
The msrpm_offsets table is global. But I think I will follow Avis
suggestions and create a static direct_access_msrs list and generate the
msrpm_offsets at module_init. This solves the problem of two independent
lists too.
But with LBR virt, maybe a fully dynamic approach is better. Just have
static lists for updating the msrpm and offset table dynamically.
