mainline inclusion from mainline-v5.12-rc1 commit 111c14159117 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV CVE: NA
-------------------------------------------------
For percent() its arguments are defined as integers; this is not consistent with its consumers which pass u32 arguments.
Thus this patch makes argument type as u32 for percent().
