We have already done this on x86 and ARM. The policy is as follows: * IRQ priority levels starting at 0 all have the same semantics and do not have special properties. The priority level is either ignored on arches which do not support programmable priority levels, or lower priority levels take precedence over higher ones. * Special-case priorty levels are specified via flags, in which case the supplied priority level is ignored.

Title: Context and IRQ APIs
Description:
This test verifies that the nanokernel CPU and context APIs operate as expected.
---------------------------------------------------------------------------
Building and Running Project:
This nanokernel project outputs to the console. It can be built and executed
on QEMU as follows:
make qemu
---------------------------------------------------------------------------
Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
make clean # discard results of previous builds
# but keep existing configuration info
or
make pristine # discard results of previous builds
# and restore pre-defined configuration info
---------------------------------------------------------------------------
