Requirements:

Allocations are multiples of 4KiB (the same on all platforms).
Needs to support contiguous allocations of N × 4KiB. N might be capped by some reasonable number, but needs to support at least 2MiB contiguous regions.
(Preferably) support allocations from specific sections of memory: i.e., you can tell the allocator "I want some memory between 0x10000000 and 0xF0000000", necessary for DMA
