This patch set implements the Linux syscalls sched_getaffinity,
sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np.
Linux has a straightforward view of the cpu sets used in affinity masks.
They are simply long (1024-bit) bit masks. This code emulates that view
while internally dealing with Windows' distribution of available CPUs among
processor groups.
* libc/include/sched.h: Include prototypes for
sched_* methods.
* libc/include/sys/sched.h: Update to POSIX
1003.1b-2008. Rework constants to allow sharing
between RTEMS and Cygwin.
* libc/include/sched.h: New file, just include sys/sched.h.
* libc/machine/spu/sys/sched.h: New file, has just sched_yield
prototype.
* libc/machine/spu/sys/utime.h: New file, has utime prototype and
struct utimbuf definition.
