interrupts with IRQ and syscalls, make phys_to_virt checked, recreate
stack on aarch64, make serial console finally line wrap and have max
height correctly, add U64Buf for when i need number debug, rename mouse
and keyboard files to kmi and merge them, add non-working pl050 support
points to aarch64 ld, add aarch64 heap, init, page tables and usermode,
make hhdm_offset a global atomic, aarch64 uses semihosting for output,
add generic PageTable type, add a function that creates and maps pages,
use allow to remove warnings, add a bufwriter so kernel panic always
works
