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

From: Greg Kroah-Hartman
Date: Mon Mar 18 2019 - 05:36:17 EST

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


From: Erik Schmauss <erik.schmauss@xxxxxxxxx>

commit 8b23570ab001c1982c8a068cde468ff067255314 upstream.

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