[PATCH] Fix module relocation errors on PowerPC

[Anton Blanchard]

Hi,

I tried grub2 on a POWER6 box and got:


Welcome to GRUB!

error: relocation overflow.
Entering rescue mode...


Modules (and therefore the heap) need to be close to the executable to
avoid requiring more complicated relocations. This patch uses the same
method sparc does and puts the heap directly above the executable.

We use the OF stack so we don't need to reserve any memory for it. Is
it time to create GRUB_MACHINE_POWERPC?
