Hi all,
This series was originally sent as "xen/arm: mm: Add limited support
for superpages" [1] and finally has grown enough to remove most of
the open-coding mappings in the boot code.
This will help to:
1) Get better compliance with the Arm memory model
2) Pave the way to support other page size (64KB, 16KB)
The previous version was spent a few months ago. So I have decided
to remove all the acked-by/reviewed-by tags.
Cheers,
