Subject: Fix bind_irq_vector() destination
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~11570
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/%22bookmarks://%22Dat/%22http:/www.example.com/cgi/%22https:/%22bookmarks:/%22Dat?a=commitdiff_plain;h=128e862878c0ae8f96ed3aee7649a32e659bf0b9;p=xen.git

Fix bind_irq_vector() destination

The "mask" covered all online cpus in the "domain". It should be used
as destination later, instead of using "domain" directly.
