[v2] This is a rebase of the original patch to Linus' current tree
From: Dave Carroll
The free_initmem function is basically duplicated in mm/init_32,
and init_64, and is moved to the common 32/64-bit mm/mem.c.
All other sections except init were removed in v2.6.15 by

freed, it is done so by pages, causing the
early memblock_alloc requests to be re-used, which in my case, caused
the device-tree to be clobbered.
This patch forces the reserved memory for initrd to be kernel page
aligned, and adds the same range extension when freeing initrd.

This patch forces initrd to be kernel page aligned, to match the mechanism used
to free reserved memory.

This patch forces all early reserved memory to be kernel page aligned, to match
the mechanism used to free reserved memory.
