Hello. Sergei Shtylyov wrote:
TX49 CPUs have a write buffer, so we need to select CPU_HAS_WB -- otherwise all Toshiba RBTX49xx kernels fail to build.
The uptimate reason is I think that <asm/system.h> doesn't include <asm/wbflush.h> if CONFIG_CPU_HAS_WB is undefined -- although, <asm/wbflush.h> handles this situation itself. Well, <asm/system.h> doesn't need the wbflush() macro in that case, so it's in his own right to not include that header...
