Your patches are all still in Greg's tree which I merge into linux-next
every day.  I have then been reverting that last patch each day.  Your
patch should be against Greg's tree (or your last patch) and then when
the fix is in Greg's tree, I will get it in linux-next and stop reverting
the other patch.

http://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.0/x86_64-gcc-4.6.0-nolibc_powerpc64-linux.tar.xz

That is am x86_64 hosted powerpc64 compiler suitable for building the
kernel.
