* Fix regression in statistic operationsAnton Vorontsov2009-12-091-6/+12
| | | | | | | | | | | In commit 98c783852039061db8c1611742660aaded0eab77 ("Use proper types for do_div") I imprudently changed some variables to an unsigned type while in some places the code actually relies on a sign. So, let's be a bit smarter now and use temporary variables. Reported-by: Wenji Huang <wenji.huang@oracle.com> Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>
* Use proper types for do_divAnton Vorontsov2009-12-011-4/+4
| | | | | | | | | | | | | | | do_div accepts unsigned 64-bit integer type for dividend, signed types would cause do_div's typecheck fail: stat-common.c: In function 'needed_space': stat-common.c:50: error: comparison of distinct pointer types lacks a cast ...same errors in time.c and tapset-timers.cxx's generated code... A fix for time.c is special, on ppc32 cycles_t is 32-bit, so technically we don't need do_div, but since the whole _stp_gettimeofday_ns() operates on 64-bit types we'd better be safe and use uint64_t for the math.
