Subject: [PATCH 3/9] bsd-user: MAP_ symbols are defined, so no need for ifdefs
Date: Thu, 16 Sep 2021 20:56:29 -0600 [thread overview]
Message-ID: <20210917025635.32011-4-imp@bsdimp.com> (raw)
In-Reply-To: <20210917025635.32011-1-imp@bsdimp.com>
All these MAP_ symbols are always defined on supported FreeBSD versions
(12.2 and newer), so remove the #ifdefs since they aren't needed.
