> The following patch series removes the IRQF_DISABLED functionality
> from the core interrupt code and runs all interrupt handlers with
> interrupts disabled.
>
> IRQF_DISABLED is kept as a define and scheduled for feature removal.
>
> I booted and stressed that patches w/o any obvious fallout on more
> than 20 different systems in my arsenal of test machines which
> includes various embedded non x86 systems.
>
> To debug eventual latency issues we (admittedly I talked acme into
> looking at that) want to extend perf with a top like tool to monitor
> the maximum runtime of interrupt handlers with the already existing
> tracepoints.
