Commit 0e6e01ff694ee ("CPM/QE: use genalloc to manage CPM/QE muram")
has changed the way muram is managed.
genalloc uses kmalloc(), hence requires the SLAB to be up and running.
On powerpc 8xx, cpm_reset() is called early during startup.
cpm_reset() then calls cpm_muram_init() before SLAB is avail

Hello,
I've just released oldworld-deb - a boot floppy that can boot Debian Installer
from the CD on OldWorld PowerMacs, such as Power Macintosh 8200.
It's based on miBoot, Linux kernel, kexec-tools, uClibc and a simple init
program written in C.
You can get the source and also a pre-built imag

The field "owner" is set by the core.
Thus delete an unneeded initialisation.
