Jprobes actually don't need to disable IRQs while calling handlers, because of how we specify the kernel interface in Documentation/kprobes.txt: ----- Probe handlers are run with preemption disabled. Depending on the architecture and optimization state, handlers may also run with interrupts disabled (e.g., kretprobe handlers and optimized kprobe handlers run without interrupt disabled on x86/x86-64). ----- So let's remove IRQ disabling from jprobes too.
