It is necessary to find a mapping of hwirq in the root IRQ domain to
the actual virq using irq_find_mapping.
Also a declaration of smp_ipi_irq_setup is corrected to denote that
this function takes a hardware IRQ number but not a virtual IRQ number.

It is necessary to find a mapping of hwirq in the root IRQ domain to
the actual virq using irq_find_mapping.
Also a declaration of smp_ipi_irq_setup is corrected to denote that
this function takes a hardware IRQ number but not a virtual IRQ number.

Yuriy Kolerov (3):
ARC: SMP: Register IPI handler using virq but not hwirq
ARCv2: MCIP: Use hwirq instead of virq for resolution of IDU IRQ
handlers
ARCv2: MCIP: Use IDU_M_DISTRI_DEST mode if there is only 1 destination
core
arch/arc/include/asm/smp.h | 4
.
However idu_irq_set_affinity always sets IDU_M_DISTRI_RR for all affinity
values. But there is no sense in setting of such mode if only 1 core must
handle a common interrupt.
