2018-12-17Implement mlock(), kind of.Jamie Liu
Currently mlock() and friends do nothing whatsoever. However, mlocking is directly application-visible in a number of ways; for example, madvise(MADV_DONTNEED) and msync(MS_INVALIDATE) both fail on mlocked regions. We handle this inconsistently: MADV_DONTNEED is too important to not work, but MS_INVALIDATE is rejected. Change MM to track mlocked regions in a manner consistent with Linux. It still will not actually pin pages into host physical memory, but: - mlock() will now cause sentry memory management to precommit mlocked pages. - MADV_DONTNEED and MS_INVALIDATE will interact with mlocked pages as described above.

2018-10-17Check thread group CPU timers in the CPU clock ticker.Jamie Liu
This reduces the number of goroutines and runtime timers when ITIMER_VIRTUAL or ITIMER_PROF are enabled, or when RLIMIT_CPU is set. This also ensures that thread group CPU timers only advance if running tasks are observed at the time the CPU clock advances, mostly eliminating the possibility that a CPU timer expiration observes no running tasks and falls back to the group leader.
