All the functionality for memblock allocation during boot was
already present in Book3e and embeded platforms. This change
just moves around some code under config conditions to make
the function happen on powernv platforms.

Tested lightly on both powernv and pseries platforms with two
16GB pages. Will appreciate comments and suggestions on the
approach.

On PowerNV while asking for 16GB pages through kernel command
line, we need to be careful not to starve the system of memory
which can make it unable to boot.

I have a patch series that does this here. How is this different ?

Hmm, did not know you have attempted this before. The link does
not open for me. Could you give the subject line for the patch
series.
