From: Arnd Bergmann <arnd@arndb.de> The kernel .data decompression is called from assembler, so it does not need a prototype, but adding one avoids this W=1 warning: arch/arm/kernel/head-inflate-data.c:35:12: error: no previous prototype for '__inflate_kernel_data' [-Werror=missing-prototypes] The same file contains a few extern declarations for assembler symbols, move those into the header as well for consistency.
