Merge tag 'ioremap-5.6' of git://git.infradead.org/users/hch/ioremap
Pull ioremap updates from Christoph Hellwig: "Remove the ioremap_nocache API (plus wrappers) that are always identical to ioremap" * tag 'ioremap-5.6' of git://git.infradead.org/users/hch/ioremap: remove ioremap_nocache and devm_ioremap_nocache MIPS: define ioremap_nocache to ioremap

- * It's useful if some control registers are in such an area and
