MIPS: BMIPS: Migrate interrupts during bmips_cpu_disable
While we properly disabled the per-CPU timer interrupt, we also need to make sure that all interrupts that can possibly have this CPU in their smp_affinity mask also have a chance to see this interrupt migrated to a CPU not being taken offline. [ralf@linux-mips.org: Fix merge conflict.] Fixes: 230b6ff57552 ("MIPS: BMIPS: Mask off timer IRQs when hot-unplugging a CPU") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Cc: cernekee@gmail.com Cc: jaedon.shin@gmail.com Cc: justinpopo6@gmail.com Cc: tglx@linutronix.de Cc: marc.zyngier@arm.com Cc: jason@lakedaemon.net Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/14488/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
