2012-06-15sysconf.c: the clock_getres function is good for NPTL as wellPeter S. Mazinger
Even if glibc reuses the syscall (bloat), we can reuse the function. Make sure, that we use it only if it is provided by the syscall and the function is really around (UCLIBC_HAS_REALTIME disables it), else we get into a loop. Signed-off-by: Peter S.

Use less stack by using same "sigset_t set" object for new and saved signal set, remove redundant clearing of set, and do not save/restore errno around sigprocmask(SIG_SETMASK) - it never changes it.

2009-09-15daemon: fix up INTERNAL_SYSCALL() usageMike Frysinger
Make sure we declare the error properly in case a port uses it, and fix the invocation of exit(). Since clone() will be returning a pid, assume that the value will not have the MSB set (negative) to simplify the error test a bit more. If gcc supports it, force this function to always be heavily optimized in a bid to avoid stack usage as much as possible.

2009-08-04Fix daemon build for no-MMU no-threads.Joseph Myers
CLONE_VM (used in no-MMU daemon) is defined in <bits/sched.h>. A build with threads ends up including <sched.h> via <pthread.h> via <bits/uClibc_mutex.h>; this indirect include does not happen for a build without threads, so this patch adds a direct <sched.h> include.
