* config/linux/proc.h: New.
* config/linux/proc.c: Include "proc.h". Do not include <sched.h>. (gomp_cpuset_popcount): Rename from cpuset_popcount. No more static. (gomp_init_num_threads): Update call to cpuset_popcount. (get_num_procs): Ditto. * config/linux/affinity.c (gomp_init_affinity): Call gomp_cpuset_popcount. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@177265 138bc75d-0d04-0410-961f-82ee72b054a4
