Kernel: Don't mix AT&T and Intel ASM syntax in boot.S
...
The rest of the file is in AT&T syntax, so for the time being, I'll
switch these instructions to AT&T too to make Clang shut up.

Kernel: Stop booting and print if PAE is not supported by the processor
...
We currently require PAE and not having it causes us to crash.
This turns that crash into an error message.

Kernel: Move PhysicalPage classes out of the heap into an array
...
By moving the PhysicalPage classes out of the kernel heap into a static
array, one for each physical page, we can avoid the added overhead and
easily find them by indexing into an array.
This also wraps the PhysicalPage into a PhysicalPageEntry, which allows
us to re-use each slot with information where to find the next free
page.

Kernel: Print if image has become too large again
...
