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

What:	The ieee80211_regdom module parameter
