Back in June, I sent a patch [1] to reduce the number of WATCHDOG_RESET
calls in flush_cache() to one per 64K. Wolfgang rejected that, saying
that the threshold should be configurable.
So here's a new version which introduces a config knob. When left at
its default, the generated code is binary identical to what one gets
before these patches.
I stumbled on the CONFIG_5xx and thought I ought to make the config
knob depend on !CONFIG_5xx, but it turns out it's better to just
remove that piece of legacy, hence the first janitorial patch.
