Subject: [PATCH 11/16] ARM: move setup functions to header
Date: Tue, 16 May 2023 17:46:00 +0200 [thread overview]
Message-ID: <20230516154605.517690-12-arnd@kernel.org> (raw)
In-Reply-To: <20230516154605.517690-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb•de>
A couple of functions are declared in arch/arm/mm/mmu.c rather than in a header,
which causes W=1 build warnings:
arch/arm/mm/init.c:97:13: error: no previous prototype for 'setup_dma_zone' [-Werror=missing-prototypes]
arch/arm/mm/mmu.c:118:13: error: no previous prototype for 'init_default_cache_policy' [-Werror=missing-prototypes]
arch/arm/mm/mmu.c:1195:13: error: no previous prototype for 'adjust_lowmem_bounds' [-Werror=missing-prototypes]
arch/arm/mm/mmu.c:1761:13: error: no previous prototype for 'paging_init' [-Werror=missing-prototypes]
arch/arm/mm/mmu.c:1794:13: error: no previous prototype for 'early_mm_init' [-Werror=missing-prototypes]
Move the declaratsion to asm/setup.h so they can be seen by the compiler
while building the definition.
