bug in asm-ppc/div64.h

Hello,

While chasing a date bug in smbfs with Urban Widmark, it so happened
that we stumbled across a bug in do_div on PPC 32bit, ie. it doesn't
work.

I attached a test case, provided by Urban. do_div is used in quite a few
places like vsprintf, the matrox fb code, etc.

When running on x86:
now: 1047238073
adjusted: 24edd64059e100
/ 10000000: 3df4e80a
1039460362

Check the run on PPC. It's wrong by quite a scale.

Any ideas on how to solve this properly ?

Cheers
