If the target kernel does not inlcude the FIXUP_ENDIAN check, coming
from a different-endian kernel will cause the target kernel to panic.
All ppc64 kernels can handle starting in big-endian mode, so return to
big-endian before branching into the target kernel.
This mainly affects pseries as secon
Older ppc64 kernels, namely those missing FIXUP_ENDIAN or opal_reinit_cpus,
will fail to boot if started via kexec from a little-endian kernel.

On powernv secondary cpus are returned to OPAL, and will then enter the

litte-endian regardless of the current endianess.

The pointer to an AFU in the adapter's list of AFUs can be null
if we're in the process of removing AFUs. The afu_list_lock
doesn't guard against this.

You're right. First I'd like to figure out what the problem is. Then
I'll build a new kernel for our PA6T system. After that I'll test it.
Afterwards the beta testers will test it. Finally I'd like to upstream
the SB600 patch.

But the first thing then is to upstream the sb600 patch.
This patch enables facility unavailable exceptions for generic facility,
FPU, ALTIVEC and VSX in /proc/interrupts listing by incrementing their
newly added IRQ statistical counters as and when these exceptions happen.
This also adds couple of helper functions which will be called from within
