Subject: mips: move cache declarations into header
Date: Mon, 4 Dec 2023 12:57:02 +0100
Some of the cache functions are declared only for their callers, e.g.
arch/mips/mm/c-r3k.c:28:15: error: no previous prototype for 'r3k_cache_size' [-Werror=missing-prototypes]
arch/mips/mm/c-r3k.c:63:15: error: no previous prototype for 'r3k_cache_lsize' [-Werror=missing-prototypes]
arch/mips/mm/c-r4k.c:1703:6: error: no previous prototype for 'r4k_cache_init' [-Werror=missing-prototypes]
arch/mips/mm/sc-mips.c:255:5: error: no previous prototype for 'mips_sc_init' [-Werror=missing-prototypes]
Move all the declarations to asm/cache.h and asm/r4kcache.h where they
can be seen by the function definitions.
