[Xen-devel] [PATCH qom-cpu 6/7] xen: Simplify halting of first CPU

[Andreas FÃrber <afaerber@xxxxxxx>]

Use the global first_cpu variable to halt the CPU rather than using a
local first_cpu initialized from qemu_get_cpu(0).

This will allow to change qemu_get_cpu() return type to CPUState
despite use of the CPU_COMMON halted field in the reset handler.
