Author: kib Date: Fri May 17 17:11:01 2019 New Revision: 347931 URL: https://svnweb.freebsd.org/changeset/base/347931 Log: Free microcode memory later. With lockless DI, pmap_remove() requires operational thread lock, which is initialized at SI_SUB_RUN_QUEUE for thread0. Move it even later where APs are started, the moment after which other boot memory like trampoline stacks is already being freed.
