Subject: [patch V3 04/37] sh/highmem: Remove all traces of unused cruft
Date: Tue, 03 Nov 2020 10:27:16 +0100 [thread overview]
Message-ID: <20201103095856.979798613@linutronix.de> (raw)
In-Reply-To: 20201103092712.714480842@linutronix.de
For whatever reasons SH has highmem bits all over the place but does
not enable it via Kconfig. Remove the bitrot.
