The branch main has been updated by kib: URL: https://cgit.FreeBSD.org/src/commit/?id=f8d3368b4346237deeaaaa91308ce78f8e2ea820 commit f8d3368b4346237deeaaaa91308ce78f8e2ea820 Author: Konstantin Belousov <kib@FreeBSD.org> AuthorDate: 2021-10-05 13:19:56 +0000 Commit: Konstantin Belousov <kib@FreeBSD.org> CommitDate: 2021-10-06 02:52:56 +0000 apic: initialize lapic_paddr statically The default value for LAPIC registers page physical address is usually right. Having this value available early makes pmap_force_invalidate_cache_range(), used on non-self-snoop machines, avoid flushing LAPIC range for early calls.
