I think these test are back from the days when there was Linus' 64bit
Alpha port and DEC's 32bit port. I could be wrong ...

I agree the ARCH64BIT patch is a good idea.

The actual construct in include/asm-mips/types.h was wrong anway, the
correct thing for MIPS would be to use the compiler defined preprocessor
symbol _MIPS_SZLONG.

[...]

#if _MIPS_SZLONG == 32
typedef __signed__ long long __s64;
typedef unsigned long long __u64;
#endif
#if _MIPS_SZLONG == 64
typedef __signed__ long __s64;
typedef unsigned long __u64;
#endif

[...]

typedef __s64 s64;
typedef __u64 u64;

[...]

If Linus accepts your patch I'll send him an appropriate patch for
2.1.74.
