From fe54b1fd49b712cd94a1846e993a515fc9394dcb Mon Sep 17 00:00:00 2001 From: Marc Carino Date: Wed, 4 Jun 2014 16:10:01 -0700 Subject: cma: increase CMA_ALIGNMENT upper limit to 12 Some systems require a larger maximum PAGE_SIZE order for CMA allocations. To accommodate such systems, increase the upper-bound of the CMA_ALIGNMENT range to 12 (which ends up being 16MB on systems with 4K pages).
