From 14673764249eb2cae4c7e9d73cb261129739563d Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Tue, 17 Jul 2012 14:05:52 -0400 Subject: [ARM] pxa: remove IRQF_SAMPLE_RANDOM which is now a no-op With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a no-op; interrupt randomness is now collected unconditionally in a very low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM flag was scheduled to be removed in 2009 on the feature-removal-schedule, so this patch is preparation for the final removal of this flag.
