Subject: genirq: do not disable IRQ_WAKEUP marked irqs on suspend
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
commit 0a0c5168df (PM: Introduce functions for suspending and resuming
device interrupts) iterates through all interrupts and disables them on
the hardware level. Some architectures have functionality implemented to
mark an interrupt source as wakeup source for suspend, but the new power
management code disables them unconditionally which breaks the resume on
interrupt functionality.
The wakeup interrupts are marked in the status with the IRQ_WAKEUP bit.
Skip the disablement for those interrupts which have the IRQ_WAKEUP bit
set.
