ad 2ddceed1d9 Hopefully fix some problems seen with MP support on non-x86, in particular ... where curcpu() is defined as curlwp->l_cpu: - mi_switch(): undo the ~2007ish optimisation to unlock curlwp before calling cpu_switchto(). It's not safe to let other actors mess with the LWP (in particular l->l_cpu) while it's still context switching. This removes l->l_ctxswtch. - Move the LP_RUNNING flag into l->l_flag and rename to LW_RUNNING since it's now covered by the LWP's lock. - Ditch lwp_exit_switchaway() and just call mi_switch() instead. Everything is in cache anyway so it wasn't buying much by trying to avoid saving old state. This means cpu_switchto() will never be called with prevlwp == NULL. - Remove some KERNEL_LOCK handling which hasn't been needed for years.		2020-01-08 17:38:41 +00:00
