Previously this would permit a stack frame to unwind into any arbitrary kernel address (including unmapped addresses).

When the registers are either the link register or the zero register we will access memory past the end of the trap frame as these are encoded as registers 30 and 31 respectively while the array they access only has 30 entries. Fix this by creating 2 helper functions to perform the operation with special cases for these registers.

Without this we could enable interrupts when they shouldn't be. It's still not quite right as it should only update the bits we care about, bit should be good enough until the correct fix can be tested.
