Jan Beulich 3278c1d066 memory: split and tighten maximum order permitted in memops ...

Introduce and enforce separate limits for ordinary DomU, DomU with
pass-through device(s), control domain, and hardware domain.

The DomU defaults were determined based on what so far was allowed by
multipage_allocation_permitted().

The x86 hwdom default was chosen based on linux-2.6.18-xen.hg c/s
1102:82782f1361a9 indicating 2Mb is not enough, plus some slack.

The ARM hwdom default was chosen to allow 2Mb (order-9) mappings, plus
a little bit of slack.

This is CVE-2015-8338 / XSA-158.
