## What's next?
### Remapping the Kernel Sections
We can use the ELF section tag to write a skeleton that remaps the kernel correctly:
```rust
for section in multiboot.elf_tag().sections() {
for page in start_page..end_page {
// TODO identity_map(page, section.writable(), section.executable())
}
}
```
TODO
The next post will be about paging again. But this time we will use the frame allocator to create a safe rust module that allows us to switch page tables and map pages. Then we will use this module and the information from the ELF sections tag to remap the kernel correctly.

Eric Kidd started the [Bare Metal Rust] series last week. Like this post, it builds upon the code from [Printing to Screen], but tries to support keyboard input instead of wrestling through memory management details ;).
