Rename MemoryManager::map to map_frames_at
To make it clearer that this API is only intented for mapping contiguous frames of physical memory (for MMIO perhaps?)

Rename physical "pages" to "frames"
AFAIK, this is the proper naming scheme. "Pages" are virtual, and "frames" physical.

Kernel: Rename ASSERT() to ensure()
Doesn't get stripped on release builds, so it shouldn't be named assert.

Some more multiple address space stuff
This page-faults. This is because the memory where the ELF should be is all zeroes, which the CPU tries to interpret.
