Hello, I recently received a kernel 'oops' about a divide error. After some research, it seems that the 'div64_s64' function used for the 'MOD'/'REM' instructions boils down to an 'idiv'. The 'dividend' is set to INT64_MIN, and the 'divisor' to -1, then because of two's complement, there is no corresponding positive value, causing the error (at least to my understanding).
Could you provide a reproducible test case for this? It will make it easy to debug the issue.
