[merged mm-stable] sh-add-asm-generic-ioh-including.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: sh: add <asm-generic/io.h> including
has been removed from the -mm tree.  Its filename was
     sh-add-asm-generic-ioh-including.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

From: Baoquan He <bhe@redhat.com>
Subject: sh: add <asm-generic/io.h> including
Date: Thu, 6 Jul 2023 23:45:12 +0800

In <asm-generic/io.h>, it provides a generic implementation of all
I/O accessors.

For some port|mm io functions, SuperH has its own implementation in
arch/sh/kernel/iomap.c and arch/sh/include/asm/io_noioport.h.  These will
conflict with those in <asm-generic/io.h> and cause compiling error. 
Hence add macro definitions to ensure that the SuperH version of them will
override the generic version.
