2015-12-08ppc64: Add a flag to tell the kernel it's booting from kexecScott Wood
It needs to know this because the SMP release mechanism for Freescale book3e is different from when booting with normal hardware. In theory we could simulate the normal spin table mechanism, but not (easily) at the addresses U-Boot put in the device tree -- so there'd need to be even more communication between the kernel and kexec to set that up.
