[PATCH 05/27] xen, cpu hotplug: Don't call cpu_bringup() in xen_play_dead()
xen_play_dead calls cpu_bringup() which looks weird, because xen_play_dead()
is invoked in the cpu down path, whereas cpu_bringup() (as the name suggests)
is useful in the cpu bringup path.
Getting rid of xen_play_dead()'s dependency on cpu_bringup() helps in hooking
on to the generic SMP booting framework....

[PATCH] xen/smp: Fixup NOHZ per cpu data when onlining an offline CPU.
The xen_play_dead is an undead function. When the vCPU is told to
offline it ends up calling xen_play_dead wherin it calls the
VCPUOP_down hypercall which offlines the vCPU. However, when the
vCPU is onlined back, it resumes execution right after
VCPUOP_down hypercall.
That was OK (albeit the API for play_dead assu...
