jdolecek 089abdad44 Rearrange process exit path to avoid need to free resources from different ... process context ('reaper'). From within the exiting process context: * deactivate pmap and free vmspace while we can still block * introduce MD cpu_lwp_free() - this cleans all MD-specific context (such as FPU state), and is the last potentially blocking operation; all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free() * process is now immediatelly marked as zombie and made available for pickup by parent; the remaining last lwp continues the exit as fully detached * MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same for both 'process' and 'lwp' exit uvm_lwp_exit() is modified to never block; the u-area memory is now always just linked to the list of available u-areas. Introduce (blocking) uvm_uarea_drain(), which is called to release the excessive u-area memory; this is called by parent within wait4(), or by pagedaemon on memory shortage. uvm_uarea_free() is now private function within uvm_glue.c. MD process/lwp exit code now always calls lwp_exit2() immediatelly after switching away from the exiting lwp. g/c now unneeded routines and variables, including the reaper kernel thread		2004-01-04 11:33:29 +00:00
