This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to
avoid invoking cache line invalidation if the driver will just handle it
later via a sync_for_cpu or sync_for_device call.

Older ARC700 cores (ARC750 specifically) lack instructions to implement
atomic r-w-w. This is problematic for userspace libraries such as NPTL
which need atomic primitives. So enable them by providing kernel assist.
This is costly but really the only sane soluton (othern than tight

Originally an initial distribution mode (its value resides in Device Tree)
for each common interrupt is set in idu_irq_xlate. This leads to the
following problems. idu_irq_xlate may be called several times during parsing
of the Device Tree and it is semantically wrong to configure an initial
distri
ARC linux uses 2 distribution modes for common interrupts: round robin
mode (IDU_M_DISTRI_RR) and a simple destination mode (IDU_M_DISTRI_DEST).
The first one is used when more than 1 cores may handle a common interrupt
and the second one is used when only 1 core may handle a common interrupt.
How
This function takes a cpu number and a virq number and registers an
appropriate handler per cpu. However smp_ipi_irq_setup is incorrectly
used in several places of ARC platform code - hwirq is passed instead
of virq. This patch is intended to clarify declaration of virq argument
to prevent passing
Multicore ARC configurations use IDU (Interrupt Distribution Unit) for
distributing of common interrupts. In fact IDU is a interrupt controller
on top of main per core interrupt controller.
All common IRQs are physically and linearly mapped to per core
interrupts. E.g. <0, 1, 2, 3> common IDU inte
