2.6.29-rc7-git2 : crash in kmem_list3_init()

[Sachin P. Sant]

While trying to boot 2.6.29-rc7-git2 on a power5 box ran into
following crash.

Unable to handle kernel paging request for data at address 0xc000000070001008

Attached here is the dmesg log with loglevel=8 mminit_loglevel=4
as well as .config used.

Tried to boot a kernel.org kernel on this box for first time so not
sure if this is a new problem or a recurring one. Will try booting
some older kernels on this box and will report the results.

Thanks
