Subject: cpumask: cpu_coregroup_mask(): s390
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9be3eec2c83848a1ca57ebad13c63c95d0df01e2;p=openwrt%2Fstaging%2Fblogic.git

cpumask: cpu_coregroup_mask(): s390

Like cpu_coregroup_map, but returns a (const) pointer.

Compile-tested on s390 (defconfig).
