 In the next post we will extend this module and add a function to modify inactive page tables. Through that function, we will create a new page table hierarchy that maps the kernel correctly using 4KiB pages. Then we will switch to the new table to get a safer kernel environment.
 
 Afterwards, we will use this paging module to build a heap allocator. This will allow us to use allocation and collection types such as `Box` and `Vec`.
