Subject: sh: Correct __xdiv64_32/div64_32 return value size.
X-Git-Tag: v2.6.23-rc1~785^2~16
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=04c7d9579f25ff0dd01efa958805f34c92bc6a71;p=linux-2.6

sh: Correct __xdiv64_32/div64_32 return value size.

These should be returning a uint32_t, whereas they were erroneously
returning a u64 before. As the register sizes are 32-bits, this doesn't
really make a lot of sense.
