Now, include/linux/errno.h is a wrapper of <asm-generic/errno.h>. Replace all include directives for <asm-generic/errno.h> with <linux/errno.h>. <asm-generic/...> is supposed to be included from <asm/...> when arch-headers fall back into generic implementation. Generally, they should not be directly included from .c files.
