Since I haven't heared back yet, time to poke the dead horse again ;-)

So basically I like Thiemo's suggestion for the fix.  But - the purpose
of the three unused 32-bit fields in struct msgid64_ds is dealing with
the year 2038 problem.  So maybe we should reorder fields like:

[...]
#if defined(CONFIG_MIPS32) && !defined(CONFIG_CPU_LITTLE_ENDIAN)
	unsigned long	__unused1;
	__kernel_time_t	msg_stime;
#else if defined(CONFIG_MIPS32) && defined(CONFIG_CPU_LITTLE_ENDIAN)
	__kernel_time_t	msg_stime;
	unsigned long	__unused1;
#else
	__kernel_time_t	msg_stime;
#endif
[...]

?

That would eventually permit extending fields to 64-bit and take care of
endianess issues.

Comments?
