X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~1908
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=2c94cd917de72d4ea82ea40b95b1b8ccc8557282;p=xen.git

build: alloc space for sched list in the link file

Creates a section to contain scheduler entry pointers that are gathered
together into an array. This will allow, in a follow-on patch, scheduler
entries to be automatically gathered together into the array for
automatic parsing.
