See http://www.infradead.org/rpr.html Sender: linux-mips-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-mips@vger.kernel.org Hi all, with the ioremap changes that did land in 5.5-rc1 ioremap_nocache is now equal to ioremap for all architectures. For most architectures including the common one this has been the case for about 20 years, but we had a few holdouts. That means ioremap_nocache is entirely superflous now and can be killed off. This series has one big scripted patch to do just that after a little prep patch to fix up the not entirely obvious mips definition. Let me know what you think and if this is something acceptable for just after -rc1.
