This series is another subset of the series I sent in May: https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00501.html
This subset contains reworked patches for: - abcd/nbcd/sbcd: remove inline, delay write back to memory and use only 3 digits (and extract it from the bifield patch as it was squashed into it) - movem: delay the update of the registers to the end of the load sequence to be able to restart the operation in case of page fault, and manage the 68020+ <-> 68000/68010 special case - cas/cas2: rewrite according Richard's comments, and use cmpxchg() in cas. 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.
