Here are patches for cpu-timers I mainly wrote to not call thread_group_cputime() in fastpath_timer_check(), which we discuss in this thread:
http://thread.gmane.org/gmane.linux.kernel/909349/focus=912327
On the way I fix some other bugs (SIGEV_NONE timer, old increase value in timer_settime()) and do other cleanups and optimizations, patch 3 however increase time when sighand->siglock is held.
0001-cpu-timers-simplify-RLIMIT_CPU-handling.patch 0002-cpu-timers-cleanup-arm_timer.patch 0003-cpu-timers-return-true-old-increase-value-in-timer_.patch 0004-cpu-timers-change-SIGEV_NONE-timer-handling.patch 0005-cpu-timer-change-arm_timer-locking.patch 0006-cpu-timers-optimize-run_posix_cpu_timers.patch
Cheers Stanislaw
