Subject: [PATCH v5 01/37] bsd-user/mips*: Remove mips support
Date: Sun,  7 Nov 2021 20:51:00 -0700	[thread overview]
Message-ID: <20211108035136.43687-2-imp@bsdimp.com> (raw)
In-Reply-To: <20211108035136.43687-1-imp@bsdimp.com>

FreeBSD is dropping support for mips starting with FreeBSD 14. mips
support has been removed from the bsd-user fork because updating it for
new signal requirements will take too much time. Remove it here since it
is a distraction.
