The patch titled Subject: mips: remove extraneous asm-generic/iomap.h include has been added to the -mm mm-nonmm-unstable branch. Its filename is mips-remove-extraneous-asm-generic-iomaph-include.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mips-remove-extraneous-asm-generic-iomaph-include.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: mips: remove extraneous asm-generic/iomap.h include Date: Mon, 4 Dec 2023 12:57:06 +0100 When this file is included before defining readq(), it misses the declarations for a couple of functions that now become unusable: lib/iomap.c:156:5: warning: no previous prototype for 'ioread64_lo_hi' [-Wmissing-prototypes] lib/iomap.c:163:5: warning: no previous prototype for 'ioread64_hi_lo' [-Wmissing-prototypes] lib/iomap.c:170:5: warning: no previous prototype for 'ioread64be_lo_hi' [-Wmissing-prototypes] lib/iomap.c:178:5: warning: no previous prototype for 'ioread64be_hi_lo' [-Wmissing-prototypes] lib/iomap.c:264:6: warning: no previous prototype for 'iowrite64_lo_hi' [-Wmissing-prototypes] lib/iomap.c:272:6: warning: no previous prototype for 'iowrite64_hi_lo' [-Wmissing-prototypes] lib/iomap.c:280:6: warning: no previous prototype for 'iowrite64be_lo_hi' [-Wmissing-prototypes] lib/iomap.c:288:6: warning: no previous prototype for 'iowrite64be_hi_lo' [-Wmissing-prototypes] The file is included again later from asm-generic/io.h, so dropping the initial include statement makes it do the right thing, both for avoiding the warning and for actually providing these functions.
