Now we have a working frame allocator. It is a bit rudimentary and cannot free frames, but it also is very fast since it reuses the Multiboot memory map and does not need any costly initialization. A future post will build upon this allocator and add a stack-like data structure for freed frames. Now we have a working frame allocator.

The next post will be about paging again. We will use the frame allocator to create a safe module that allows us to switch page tables and map pages.
