[OpenBIOS] [PATCH 0/8] SPARC64 Forth context rework

This patchset is aimed at unifying the code used to preserve CPU context
when switching from client programs into Forth, via either the CIF or
interrupt handlers.

It is part of a longer process to enable access to saved CPU context state 
from within Forth which will eventually enable proper implementation of the
init-program and go words.
