Not in the slightest. The question is how on Earth struct msqid64_ds
isn't botched on MIPS.

It is botched.

#if defined(CONFIG_32BIT) && defined(CONFIG_CPU_LITTLE_ENDIAN) come out in the userspace header file.

On mips it would appear that asm/msgbuf.h is not unique in this manner:

# grep CONFIG *.h
fcntl.h:#ifdef CONFIG_32BIT
fcntl.h:#endif /* CONFIG_32BIT */
ioctls.h:#define TIOCSERCONFIG 0x5488
msgbuf.h:#if defined(CONFIG_32BIT) && !defined(CONFIG_CPU_LITTLE_ENDIAN)
msgbuf.h:#if defined(CONFIG_32BIT) && defined(CONFIG_CPU_LITTLE_ENDIAN)
msgbuf.h:#if defined(CONFIG_32BIT) && !defined(CONFIG_CPU_LITTLE_ENDIAN)
msgbuf.h:#if defined(CONFIG_32BIT) && defined(CONFIG_CPU_LITTLE_ENDIAN)
msgbuf.h:#if defined(CONFIG_32BIT) && !defined(CONFIG_CPU_LITTLE_ENDIAN)
msgbuf.h:#if defined(CONFIG_32BIT) && defined(CONFIG_CPU_LITTLE_ENDIAN)

swab.h: * Having already checked for CONFIG_CPU_MIPSR2, enable the
swab.h:#ifdef CONFIG_64BIT
