No.
Try a make for mips, and look at includes you end up with. You will
find it goes something like:
# 1 "./arch/mips/include/asm/errno.h" 1
# 11 "./arch/mips/include/asm/errno.h"
# 1 "./arch/mips/include/uapi/asm/errno.h" 1
# 16 "./arch/mips/include/uapi/asm/errno.h"
# 1 "./include/uapi/asm-generic/errno-base.h" 1
# 17 "./arch/mips/include/uapi/asm/errno.h" 2
and this results in
#define EOPNOTSUPP 122 /* Operation not supported on transport
endpoint */
not what you get from asm-generic/errno.h:
#define EOPNOTSUPP 95 /* Operation not supported on transport
endpoint */
