Subject: powerpc/mpic: Make distribute_irqs obey MPIC_SINGLE_DEST_CPU
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7bd9fc556d8f5752c86fa09cbaa3c1c3ab5da86f;p=openwrt%2Fstaging%2Fblogic.git

powerpc/mpic: Make distribute_irqs obey MPIC_SINGLE_DEST_CPU

Previously we were setting an illegal configuration on mpc85xx
MPICs if CONFIG_IRQ_ALL_CPUS is enabled (which for some reason it is
in mpc85xx_smp_defconfig).
