Wire up the generic support for exposing CPU feature bits via the
modalias in /sys/device/system/cpu. This allows udev to automatically
load modules for things like crypto algorithms that are implemented
using optional instructions.

Russell,

do you have any concerns regarding this patch? If not, I will drop it
into the patch system.
It's still something I need to look at... I've been offline last week,
and sort-of offline the previous week, so I'm catching up.
Hi Russell,

Any thoughts yet?
None, and the patch is well buried now that it'll take me a while to
find... back in mid-October?  Yea, I'll have to drop everything and
go digging through my mailboxes to find it... and I'm just catching
up (again) after a week and a bit's time offline - yep, it's wonderful
timing.  Sorry, no time to look at it right now, you're not the only
one wanting my attention at the moment.
No worries. It is not exactly urgent, but it is a useful enhancement
nonetheless.
Please try again in about a week's time - don't leave it a few months,
and please include the patch.
OK
