The patch titled Subject: sparc64: fix up fallout from enabling -Wmissing-prototypes has been added to the -mm mm-nonmm-unstable branch. Its filename is arch-sparc-fix-up-fallout-from-enabling-wmissing-prototypes.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/arch-sparc-fix-up-fallout-from-enabling-wmissing-prototypes.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: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Subject: sparc64: fix up fallout from enabling -Wmissing-prototypes Date: Thu Dec 21 04:33:25 PM PST 2023 Fix sparc64 allmodconfig build errors caused by enabling -Wmissing-prototypes. - Symbols only used from assembly were given local prototypes - A couple of missing inclusions were added - Define some functions to be static - vmemmap_free() is only needed if CONFIG_MEMORY_HOTPLUG - add new arch/sparc/include/asm/irq_work.h for arch_irq_work_raise() - move prom_cif_init() prototype to header, fix longstanding prom_cif_init() borkage. - various function declarations were moved from .c into shared .h Fixes: c6345dfa6e3e ("Makefile.extrawarn: turn on missing-prototypes globally") Reported-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: "David S.
