[PATCH v3 3/9] bsd-user/mmap.c: MAP_ symbols are defined, so no need for


From: Warner Losh
Subject: [PATCH v3 3/9] bsd-user/mmap.c: MAP_ symbols are defined, so no need for ifdefs
Date: Fri, 8 Oct 2021 15:23:38 -0600

All these MAP_ symbols are always defined on supported FreeBSD versions
(12.2 and newer), so remove the #ifdefs since they aren't needed.
