I tested the patchset with large memblocks (2GB) on x86_64, and worked
fine as well.
On powerpc I was only able to test it on normal memblocks, but I will check
if I can boost the memory there to get large memblocks.

And about arm64, I will talk to Jonathan off-list to see if we can do the same.

Btw, in the meantime, we could get some parts reviewed perhaps.
