Subject: [PATCH 4.9 01/31] ACPICA: Reference Counts: increase max to 0x4000 for large servers

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Erik Schmauss <erik.schmauss@...el.com>

commit 8b23570ab001c1982c8a068cde468ff067255314 upstream.

Increase the reference count limit to 0x4000 as the current one is
not sufficient for some large server systems.
