[Mavrick] SRU: Set maximum of domain visible memory to 70G

[Stefan Bader]

SRU justification:

Impact: The config option XEN_MAX_DOMAIN_MEMORY controls how much memory
a Xen instance is seeing. The default for 64bit is 32GB, which is the
reason that m2.4xlarge instances only report this amount of memory.

Fix: Setting this limit to 70GB as there is a known restriction for
t1.micro instances at about 80GB.

Testcase: Booted m2.4xlarge with this set to 32GB shows 32GB of memory,
when set to 70GB, it correctly reports 68GB. Booted a t1.micro as well
to verify this has not caused problems there.

Subject: [PATCH] UBUNTU: Set maximum of domain visible memory to 70G

BugLink: http://bugs.launchpad.net/bugs/667796

Otherwise the largest instances will be stuck with 32G of memory. 70G
was chosen as there are some known problems on small instances around
80GB and the largest instance is using 68GB.
