This code is rather broken in an obvious way, starting from:
unsigned long long __n; \
\
__high = *__n >> 32; \
__low = __n; \
where `__n' is used uninitialised. Since this is my code originally I'll
look into it; we may want to reinstate `do_div' too, which didn't have to
be removed in the first place.
Also commit e8e4eb0fbeda ("asm-generic/div64: Fix documentation of
do_div() parameter") was an incomplete documentation fix.
Huacai, thanks for your investigation! Please be more careful in
verifying your future submissions however.
