[Xen-devel] [PATCH 1/2] xen: remove xen_vcpu_init

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

No need for xen_vcpu_init anymore:

- the RTC emulator doesn't have any periodic timers continuously running
even in absence of guest interactions anymore;

- qemu_dummy_start_vcpu takes care of disabling TCG for us, so we don't
need to do it manually here.
