Maybe... unfortunately this comment is after Linus has merged the patch.
Might as well leave it as is since we know it works.

memmap= is not supported on ARM - there is no code to parse or
Khasim,
As far as I understand there are two options:
1. memmap

This has some issue with 2.6.27 and fixed in later versions(not sure

Used to be you needed to build with CONFIG_ARCH_DISCONTIGMEM_ENABLE did you do
