[PATCH] hrtimers: fix timer_create(2) && SIGEV_NONE
From: george anzinger <george@mvista.com>
- Fix the sig_notify filtering code for the timer_create system call to
properly check for the signal number being small enought, but only if
SIG_NONE is not specified.
- Eliminate useless test of sig_notify.
