986d1590cb [kernel][vm] first stab at a virtual memory manager 
Add kernel/vm code to handle memory management in large page-aligned
regions of virtual space. This is composed via a pmm (physical
memory manager) and vmm (virtual memory manager) and the architecturally
specific code to manage the mmu.

Add ARMv7 paging code.

it has essentially no effect.

33c82250a5 [arm] fix problem with gcc 4.4 to ensure the boot code is in the binary 
seems that gcc 4.4 or the newer binutils likes to put linker generated
shims first in link order. Tweak the boot code to use a special section
that is ordered first by the linker script.
