[PATCH v2 00/15] target/m68k: Conditional traps + trap cleanup

[Richard Henderson]

Supercedes: <20211130103752.72099-1-richard.henderson@linaro.org>

Reviewing v1, Laurent rightly noticed that there were changes
required in m68k_interrupt_all.  Matching sysemu, there were
changes needed in the linux-user cpu_loop.

In the process, I found a number of other trap related bugs,
and some strace problems.  I cherry-picked the linux-user/m68k
patch from my outstanding force_sig_fault patch set, to avoid
conflicts with that one.
