It seems IRQF_SHARED | IRQF_DISABLED has already been discussed several
times on LKML:


Especially this message


makes me think that Linus will reject my proposed patch for the lockup
problem as it implements choice (c) on his list.

Alan: should I try to implement his choice (f) insteadn, i.e. drop
IRQF_DISABLED from USB HCD interrupts and disable interrupts in
usb_hcd_irq() instead?
