    Subject[PATCH 4.14 08/85] genirq: Let GENERIC_IRQ_IPI select IRQ_DOMAIN_HIERARCHY
    Date
    From: Marc Zyngier <maz@kernel.org>

    [ Upstream commit 151a535171be6ff824a0a3875553ea38570f4c05 ]

    kernel/irq/ipi.c otherwise fails to compile if nothing else
    selects it.

    Fixes: 379b656446a3 ("genirq: Add GENERIC_IRQ_IPI Kconfig symbol")
