[PATCH 0/7] xen/mm: Normalize per-domain page counters, >16 TiB per domain

[Bernhard Kaindl <bernhard.kaindl@citrix.com>]

Summary of a comment by Jan Beulich motivating this submission:
> Considering that systems (and hence guests) only ever get larger, we
> should consider to normalize per-domain page counters to unsigned long.

This series enables supporting guests >16 TiB in the future
once the system support for machines >16 TiB is implemented.

1. xen/mm: Normalize common per-domain page counters to unsigned long
2. x86/mm: Normalize X86 per-domain page counters to unsigned long
3. xen/mm: Static memory: Widen assign_pages(nr) to unsigned long
4. xen/mm: Static memory: Widen domstatic plumbing to unsigned long
5. xen/mm: device-tree: Widen static page counts to unsigned long
6. xen/arch/x86/dom0_build.c: Extend the upper limit for Dom0's max_pages
7. tools/libs/stat/xenstat.c: Extend the "no maximum" sentinel for max_pages

This series is based on the NUMA claim sets v7 series:
