Date: Sat, 20 Aug 2022 08:31:17 +0800 From: Baoquan He <bhe@...hat.com> To: linux-kernel@...r.kernel.org Cc: linux-mm@...ck.org, akpm@...ux-foundation.org, hch@...radead.org, agordeev@...ux.ibm.com, wangkefeng.wang@...wei.com, linux-arm-kernel@...ts.infradead.org, Baoquan He <bhe@...hat.com> Subject: [PATCH v2 03/11] mm: ioremap: allow ARCH to have its own ioremap definition Architectures like xtensa, arc, can be converted to GENERIC_IOREMAP, to take standard ioremap_prot() and ioremap_xxx() way. But they have ARCH specific handling for ioremap() method, than standard ioremap() method. In oder to convert them to take GENERIC_IOREMAP method, allow these architecutres to have their own ioremap definition. This is a preparation patch, no functionality change.
