Subject: [PATCH] 1/2 Add exposure of the irq delivery mask on x86


This exposes a delivery mask in /proc/<irq>/mask for the userspace irq
balancer to use in its calculations.

The only current consumer of this on x86 would be voyager I think (patch
for voyager follows).

What exactly are you trying to expose? These patches look to just show
what cpus are on-line. Wouldn't this just be the cpu_online_map in all
cases? I guess I am a little confuses by what a "delivery mask" is.

Thanks,

Sorry I read the voyager.txt file and I understand what you are trying
to do now.
