powerpc/kexec: Switch to a static PACA on the way out
With dynamic PACAs, the kexecing CPU's PACA won't lie within the kernel static data and there is a chance that something may stomp it when preparing to kexec. This patch switches this final CPU to a static PACA just before we pull the switch. Signed-off-by: Matt Evans <matt@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
