Hmm...downloaded 2.6.9, patched to 2.6.10-rc2, patched to 2.6.10-rc2-mm4. Tried
building and got the following error:

[cfriesen@hsdbsk204-83-218-112 linux-2.6.10-rc2-mm4]$ make
CHK include/linux/version.h
make[1]: `arch/ppc/kernel/asm-offsets.s' is up to date.
CHK include/linux/compile.h
CHK usr/initramfs_list
GEN .version
CHK include/linux/compile.h
UPD include/linux/compile.h
CC init/version.o
LD init/built-in.o
LD .tmp_vmlinux1
arch/ppc/mm/built-in.o(.init.text+0x5f4): In function `paging_init':
: undefined reference to `pgd_offset_is_obsolete'
make: *** [.tmp_vmlinux1] Error 1

Any ideas?

Chris
