"minimal ARM architecture version" as the compile flag for ARM support.
This to be able to optimize a kernel build for a specific SoC (or family).
* Research stack unwinding to implement backtrace support for KDL & friends.
* B_MAX_CPU_COUNT should be fixed to be a more sensible future-proof value then 1
* KDL disasm module.

* Bootloader TODOs:
- Better handling of memory ranges. Currently no checks are done, and
memory is assumed to be a single contiguous range, and the "input"
ranges for mmu_init are setup, but never considered.
- Allocate the pagetable range using mmu_allocate() instead of identity
mapping it. That way, there's a bit more flexibility in where to place
it both physically and virtually. This will need a minor change on the
kernel side too (in the early pagetable allocator).
