Hi, Arnd: These 2 patch will cause sparc building error in any order. commit af84603e339a6832052071aca1f2a16b8963cc2e Author: Greentime Hu <green.hu@xxxxxxxxx> Date: Tue Feb 13 17:09:07 2018 +0800 sparc: io: To use the define of ioremap_[nocache|wc|wb] in asm-generic/io.h A commit for the nds32 architecture bootstrap("asm-generic/io.h: move ioremap_nocache/ioremap_uc/ioremap_wc/ioremap_wt out of ifndef CONFIG_MMU") will move the ioremap_nocache out of the CONFIG_MMU ifdef. This means that in order to suppress re-definition errors we need to remove the #define in io_32.h. Also, the change adds a prototype for ioremap where size is size_t and offset is phys_addr_t so fix that as well.
