Matthew Dillon d74ac6819b Compromise for critical*()/cpu_critical*() recommit. Cleanup the interrupt ... disablement assumptions in kern_fork.c by adding another API call, cpu_critical_fork_exit(). Cleanup the td_savecrit field by moving it from MI to MD. Temporarily move cpu_critical*() from <arch>/include/cpufunc.h to <arch>/<arch>/critical.c (stage-2 will clean this up). Implement interrupt deferral for i386 that allows interrupts to remain enabled inside critical sections. This also fixes an IPI interlock bug, and requires uses of icu_lock to be enclosed in a true interrupt disablement. This is the stage-1 commit. Stage-2 will occur after stage-1 has stabilized, and will move cpu_critical*() into its own header file(s) + other things. This commit may break non-i386 architectures in trivial ways. This should be temporary. Reviewed by: core Approved by: core		2002-03-27 05:39:23 +00:00
