From: Daniel Wagner <daniel.wag...@bmw-carit.de>
Instead proving its own arch_local_irq_save() and arch_irqs_disabled()
version use the generic version from asm-generic/irqflags.h.
A nice side effect is that um gets a few additional arch_ functions
as well.
One problem though is the include for the signals. I could figured out
which header file to pick without trigger a bunch of header include
clashes. Leaving it away works though it is surely not the best
practice.
