The kernel has access to neither the C library nor the standard C headers.
The kernel is coded in GNU C.
The kernel lacks the memory protection afforded to user-space.
The kernel cannot easily execute floating-point operations.
The kernel has a small per-process fixed-size stack.
Because the kernel has asynchronous interrupts, is preemptive, and supports SMP,
synchronization and concurrency are major concerns within the kernel.
Portability is important.
