mm: refactor page frame allocator 
This is part 3 of the mm subsystem overhaul.
The allocator doesn't rely on mutexes anymore and
uses individual per-order spinlocks instead.
Also, it is aware of multiple memory zones (normal
and DMA) as well as emergency reserves.
Page bitmaps take up 50 % less overhead now.

mm: refactor entire mm subsystem, part 1 
Another one of those larger endeavours that take
multiple commits.  This first one introduces the
basic vm_page data structure, as well as the x86
bootstrap code for initializing it.
