[PATCH v3] panic: prevent panic_timeout * 1000 from overflow

integer, also in case the loop counter i might never be greater than u64 timeout = panic_timeout*1000, elevate its precision to u64(timer) as well. The same applies to timer_next replacing i_next which is initialized to 0. Signed-off-by: Changming Liu --- Changes in v3: - change the loop in panic

[PATCH v2] panic: prevent panic_timeout * 1000 from overflow

From: Changming Liu Since panic_timeout is an integer passed-in through sysctl, the loop boundary panic_timeout * 1000 could overflow and result in a zero-delay panic when panic_timeout is greater than INT_MAX/1000. Fix this by moving 1000 to the left, also in case i/1000 might never be greater
