[PATCH 3/4] powerpc: Use IRQF_NO_SUSPEND not IRQF_TIMER for non-timer interrupts
in [Kernel]

Prev: [PATCH 4/5] memcg : generic file stat accounting
Next: [PATCH 1/4] irq: Add new IRQ flag IRQF_NO_SUSPEND
From: Ian Campbell on 29 Jul 2010 06:20 kw_i2c_irq and via_pmu_interrupt are not timer interrupts and therefore should not use IRQF_TIMER. Use the recently introduced IRQF_NO_SUSPEND instead since that is the actual desired behaviour.
