Subject: powerpc-add-purgatory-for-kexec_file_load-implementation-fix
The change below to arch/powerpc/purgatory/Makefile fixes the cross build
from ppc64 BE to ppc64 LE.
I also noticed that building the purgatory during archprepare is not necessary,
so I also made the change below to arch/powerpc/Makefile.
I'm preparing a v8 of the kexec_file_load implementation for powerpc series
with those changes and will send it shortly.

I noticed that both the kexec_file_load implementation for powerpc and the
kexec hand-over buffer patches were removed from -mm and linux-next.
kexec_file_load is desired even without the kexec hand-over buffer feature
because it enables one to only allow loading of signed kernels, and also to
measure the loaded kernel and initramfs. There are users interested in both
of those features on powerpc and since IMA already supports them via its
hooks in kexec_file_load, the only missing piece in the puzzle is the
kexec_file_load implementation itself.
The latest version of the kexec_file_load series is v8:
https://lists.infradead.org/pipermail/kexec/2016-September/017123.html
which is also part of the next-kexec-restore branch at
git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity.git
I'm not aware of any issue with v8, so could you consider it for -mm and
linux-next independently of the kexec buffer hand-over series?
