Hi Sasha,
Could you drop this?
This prevents probing too much functions, and we will drop it
from upstream. Anyway, commit a50480cb6d61 ("kprobes/x86:

So please

Prohibit probing on IRQ handlers in irqentry_text because
if it interrupts user mode, at that point we haven't changed
to kernel space yet and which eventually leads a double fault.
E.g.
# echo p
3 matches
