The IRQF_DISABLED flag was removed in 4.1 in commit
"genirq: Remove the deprecated 'IRQF_DISABLED' request_irq() flag entirely" [1].
By default all interrupt handlers are now run with interrupts disabled and
therefore should all be considered "fast interrupts". Any driver that was still
using the flag will now lock interrupts directly in the handler in case running
on an older kernel that is not disabling interrupts when running the handler.
