- Store the exception program counter (from EPCR) and exception status
register (from ESR) also during the exception. A runtime system may
replace them thereby to implement a thread switch.
* or1k/exception-asm.S: Store missing state
- We do not need a red zone here, as we do not operate on the current
stack, but always use the clear exception stack. Also reserve two
extra words for the context to store EPCR and ESR.
