Hello Dave,
Thanks for the quick review and for your comments.
I'll separate the change to add arch_walk_system_ram and the change to add
kexec_locate_mem_hole into different patches, and add error handling for
KEXEC_ON_CRASH.

Hi Ben,
I could send you a patch but it doesn't work with the three PowerPC
commits. I think we have to fix the boot issue at first. After that we
can integrate the first patch for the Nemo board.

Dear all,
Debian decided to switch to using CONFIG_FB_RADEON=m (Mach64 and
Rage128 are still built-in). Since CONFIG_FB_OF=y and can never be a
module, this means for PowerMac+radeon users that Open Firmware is
always the implementation taken from the Frame Buffer:

I can't compile the RC3 without the PowerPC commits. Our kernel lost the
