2.6.29-rc6-rt2 fails for powerpc

[jeff angielski]

1. Git clone of the latest 2.6.29-rc6.
2. Applied the 2.6.29-rc6-rt2 patch.
3. Copied XXX config from arch/powerpc/configs to .config
4. make -j2 ARCH=powerpc oldconfig
5. make -j2 ARCH=powerpc 

It fails with redefinition errors of the rwsem stuff from
arch/powerpc/include/asm/rwsem.h and include/linux/rt_lock.h.

Anybody else having this problem?  Google was not my friend, nor the RT
Wiki... 

The detailed compile output is here:
