I've checked it doesn't break coldfire support: http://wiki.qemu.org/download/coldfire-test-0.1.tar.bz2 but it can't boot a 680x0 processor kernel. v2: - movem: don't use temp variable mask2 - bcd: delay register write back fix bcd_add() to add X define bcd_sub() instead of bsd_neg() - cas2: make it atomic with "parallel_cpus" and cpu_loop_exit_atomic() (and 64bit cmpxchg() if possible) Richard: This series doesn't use your "areg writeback" series, but if you resend your series (with cmpm patches squashed and the fix for writeback_mask), I will rebase this series on top of yours.
