[PATCH 14/17] [ARM] pxa: remove IRQF_SAMPLE_RANDOM which is now a no-op

From: Theodore Ts'o
Date: Tue Jul 17 2012 - 18:09:19 EST


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.
