Why is this under CONFIG_KEXEC? It'll also be needed for CPU hotplug.
Hi Scott,
Thanks for the valuable comment raised before and we have updated the
patches accordingly. Please review the updated patch set and ACK if
they are good to you. We hope it can be applied in this window.

Subject: RE: [linuxppc-release] [PATCH v5 1/5] powerpc/85xx: implement
hardware timebase sync
Hi Scott and Kumar,
Do you have comments for these patches?
http://patchwork.ozlabs.org/patch/158484/
http://patchwork.ozlabs.org
Do hardware timebase sync. Firstly, stop all timebases, and transfer
the timebase value of the boot core to the other core. Finally,
start all timebases.
Only apply to dual-core chips, such as MPC8572, P2020, etc.
