Marcel Moolenaar 8d077f48f0 Reimplement the lazy FP context switching: ... o Move all code into a single file for easier maintenance. o Use a single global lock to avoid having to handle either multiple locks or race conditions. o Make sure to disable the high FP registers after saving or dropping them. o use msleep() to wait for the other CPU to save the high FP registers. This change fixes the high FP inconsistency panics. A single global lock typically serializes too much, which may be noticable when a lot of threads use the high FP registers, but in that case it's probably better to switch the high FP context synchronuously. Put differently: cpu_switch() should switch the high FP registers if the incoming and outgoing threads both use the high FP registers.		2009-10-31 22:27:31 +00:00
