[POWERPC] Fix build errors when BLOCK=n
These are the symptom error messages: CC arch/powerpc/kernel/setup_32.o In file included from include/linux/blkdev.h:17, from include/linux/ide.h:13, from arch/powerpc/kernel/setup_32.c:13: include/linux/bsg.h:67: warning: 'struct request_queue' declared inside parameter list include/linux/bsg.h:67: warning: its scope is only this definition or declaration, which is probably not what you want include/linux/bsg.h:71: warning: 'struct request_queue' declared inside parameter list In file included from arch/powerpc/kernel/setup_32.c:13: include/linux/ide.h:857: error: field 'wrq' has incomplete type CC arch/powerpc/kernel/ppc_ksyms.o In file included from include/linux/blkdev.h:17, from include/linux/ide.h:13, from arch/powerpc/kernel/ppc_ksyms.c:15: include/linux/bsg.h:67: warning: 'struct request_queue' declared inside parameter list include/linux/bsg.h:67: warning: its scope is only this definition or declaration, which is probably not what you want include/linux/bsg.h:71: warning: 'struct request_queue' declared inside parameter list In file included from arch/powerpc/kernel/ppc_ksyms.c:15: include/linux/ide.h:857: error: field 'wrq' has incomplete type The fix tries to use the smallest scope CONFIG_* symbols that will fix the build problem. In this case <linux/ide.h> needs to be included only if IDE=y or IDE=m were selected. Also, ppc_ide_md is needed only if BLK_DEV_IDE=y or BLK_DEV_IDE=m Moved the EXPORT_SYMBOL(ppc_ide_md) from ppc_ksysms.c next to its declaration in setup_32.c which made <linux/ide.h> not needed. With <linux/ide.h> gone from ppc_ksyms.c, <asm/cacheflush.h> is needed to address the following warnings and errors: CC arch/powerpc/kernel/ppc_ksyms.o arch/powerpc/kernel/ppc_ksyms.c:122: error: '__flush_icache_range' undeclared here (not in a function) arch/powerpc/kernel/ppc_ksyms.c:122: warning: type defaults to 'int' in declaration of '__flush_icache_range' arch/powerpc/kernel/ppc_ksyms.c:123: error: 'flush_dcache_range' undeclared here (not in a function) arch/powerpc/kernel/ppc_ksyms.c:123: warning: type defaults to 'int' in declaration of 'flush_dcache_range' Signed-off-by: Emil Medve <Emilian.Medve@Freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
