Stephen Boyd talked about the need to be able to mask/unmask interrupts from
client code in the Qualcomm platform as well - most likely to block wakeup
sources(?)
What's wrong with irq_disable?
The problem is irq_disable() is lazy and doesn't actually disable the
interrupt.
Nothing prevents you from adding your own irq_disable() callback for
those interrupts. Just the default is lazy.

Thanks,
