Browse Source 
Fix `manual_div_ceil` clippy warning as suggested by rust 1.85.1.

```console
error: manually reimplementing `div_ceil`
   --> dbs_interrupt/src/kvm/mod.rs:202:24
    |
202 |         let elem_cnt = (total_sz + elem_sz - 1) / elem_sz;
    |                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: consider using `.div_ceil()`: `total_sz.div_ceil(elem_sz)`
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#manual_div_ceil
    = note: `-D clippy::manual-div-ceil` implied by `-D warnings`
    = help: to override `-D warnings` add `#[allow(clippy::manual_div_ceil)]`
```
