Subject: cpumask: use topology_core_cpumask/topology_thread_cpumask instead of cpu_core_map... 
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c69fc56de1df5769f2ec69c915c7ad5afe63804c;p=linux-beck.git

cpumask: use topology_core_cpumask/topology_thread_cpumask instead of cpu_core_map/cpu_sibling_map

Impact: cleanup

This is presumably what those definitions are for, and while all archs
define cpu_core_map/cpu_sibling map, that's changing (eg. x86 wants to
change it to a pointer).
