I think there is some scope to re-factor some code that is shared with
cpu_memory_rw_debug. In fact rather than using this to feed
mcd_read_write_memory() maybe you really just want a
cpu_physical_memory_rw_debug()?
Although as you are going from vaddr anyway where does
cpu_memory_rw_debug() fail for you?

Next change in the series will run vcpu_init asynchronously, which will
make it run *after* resume callback as well. So we fix this now.

least once during the check-tcg checks.

As we expand the per-vCPU data for plugins we don't want to pollute
CPUState. For now this just moves the plugin_mask (renamed to
event_mask) as the memory callbacks are accessed directly by TCG
generated code.

The previous change made sure that any idle/resume cb call will not be
done before initializing plugin for a given vcpu.

shouldn't be totally obtuse. Let the user know what they can and can't
expect with the various instrumentation options.
