-Subject: fix undefined behavior in sched.h cpu_set_t usage
-
-since cpu sets can be dynamically allocated and have variable size,
-accessing their contents via ->__bits is not valid; performing pointer
-arithmetic outside the range of the size of the declared __bits array
-results in undefined beahavior. instead, only use cpu_set_t for
-fixed-size cpu set objects (instantiated by the caller) and as an
-abstract pointer type for dynamically allocated ones. perform all
-accesses simply by casting the abstract pointer type cpuset_t * back
-to unsigned long *.
