alc 336d354baa - Introduce and use a new tunable "debug.mpsafevm". At present, setting ... "debug.mpsafevm" results in (almost) Giant-free execution of zero-fill page faults. (Giant is held only briefly, just long enough to determine if there is a vnode backing the faulting address.) Also, condition the acquisition and release of Giant around calls to pmap_remove() on "debug.mpsafevm". The effect on performance is significant. On my dual Opteron, I see a 3.6% reduction in "buildworld" time. - Use atomic operations to update several counters in vm_fault().		2004-08-16 06:16:12 +00:00
