Subject: [PATCH 17/17] random: final removal of IRQF_SAMPLE_RANDOM

The IRQF_SAMPLE_RANDOM flag is finally gone from the kernel tree, only
three years late.  :-)

-What:	IRQF_SAMPLE_RANDOM
-Check:	IRQF_SAMPLE_RANDOM
-When:	July 2009
-
-Why:	Many of IRQF_SAMPLE_RANDOM users are technically bogus as entropy
-	sources in the kernel's current entropy model. To resolve this, every
-	input point to the kernel's entropy pool needs to better document the
-	type of entropy source it actually is. This will be replaced with
-	additional add_*_randomness functions in drivers/char/random.c
