virtio-mem currently only supports device block sizes that span at most

a single Linux memory block. For example, gigantic pages in the hypervisor

result on x86-64 in a device block size of 1 GiB - when the Linux memory

block size is 128 MiB, we cannot support such devices (we fail loading the

driver). Of course, we want to support any device block size in any Linux

VM.

Bigger device block sizes will become especially important once supporting

VFIO in QEMU - each device block has to be mapped separately, and the

maximum number of mappings for VFIO is 64k. So we usually want blocks in

the gigabyte range when wanting to grow the VM big.

- Performs some cleanups

- Factors out existing Sub Block Mode (SBM)

- Implements memory hot(un)plug in Big Block Mode (BBM)

I need one core-mm change, to make offline_and_remove_memory() eat bigger

chunks.

I am trying to apply this patch set, while found I can't 'git fetch' this
repo. Is there any other repo I would apply this patch set?
