[patch 0/2] Run interrupt handlers always with interrupts disabled

[Thomas Gleixner]

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.

Thanks,

	tglx
