InitRD: Use MMU::translate_physical_address instead of allocating VM
...
This one is a perfect candidate, since we're just mapping a fixed continuous range of physical memory to virtual memory.

x86_64/MMU: Map all physical memory into the higher half instead of using recursive mapping
...
This still has a few problems. Notably, we are not using huge pages for this mapping, which would be a lot more efficient.
Right now, used memory is 8.1 MiB at boot for a 256MiB system.
But after improving it, this system will be much better than recursive mapping.
fork() will be MUCH easier to implement, for example.

kernel: Switch to a stack we control for the main task as soon as we leave early boot
...
This is probably pointless as the main task only exists up until the point where the Scheduler starts running, but some init code was running into a stack overflow due to the fact that we only had one bootloader-provided page of stack.
This should probably be changed afterwards.

Heap: Fix GPF caused when making many small allocations

Apparently space was too tight to split(), but we did it anyways, corrupting the next block.
This patch fixes this behavior.
