With today's next release, eHEA network interface on couple
of power6 boxes fails to initialize.

I tracked this problem to the following commit.
commit 7545ba6f82924d4523f8f8a2baf2e517a750265d
powerpc/mm: Bump SECTION_SIZE_BITS from 16MB to 256MB
If i revert this commit, the network interface is initialized
properly. Verified this on two different power6 boxes.
Thanks
