I am not sure when this started, but noticed that sched_getaffinity is
not working in -rc4.

[pid 6254] sched_getaffinity(0, 128, 0x7f80586b1fe0) = -1 EINVAL
(Invalid argument)

Here is a simple program for reproduction:

#include <sched.h>

int main(void)
{
cpu_set_t mask;
int ret;

ret = sched_getaffinity(0, sizeof(mask), &mask);
if (ret < 0)
perror("getaffinity");

return ret;
}

If I get time, I will bisect this later today.

Regards,
-Greg
