powerpc: fix implicit use of cache.h in kernel/firmware.c This file only needs export.h to get EXPORT_SYMBOL, but in doing so, it uncovers an implicit use of linux/cache.h as follows: CC arch/powerpc/kernel/firmware.o arch/powerpc/kernel/firmware.c:20: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__read_mostly' arch/powerpc/kernel/firmware.c:21: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__used' make[2]: *** [arch/powerpc/kernel/firmware.o] Error 1 Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> 2011-07-22 19:07:20 +00:00			`#include <linux/export.h>`

powerpc: Make powerpc_firmware_features __read_mostly We use firmware_has_feature quite a lot these days, so it's worth putting powerpc_firmware_features into __read_mostly.

[PATCH] powerpc: Rename and export ppc64_firmware_features We need to export ppc64_firmware_features for modules. Before we do that I think we should probably rename it to powerpc_firmware_features.
