Kernel: Be more clever with physical memory
...
Initially allocate all physical memory except kernel memory and boot
modules. Before we just skipped all memory before kernel boot modules.
Also release memory used by boot modules after the kernel is up and
running. Once the boot modules are loaded, there is no need to keep them
in memory.

Kernel: Heap allows us to take free pages.
...
The API is kinda weird and will probably be reworked in near future
but this will work for now :)
