Dear Gaurav.....
I am not an expert on this issue, but allow me to share my idea...

you mean this check, right? Well IMHO, "cli" certainly masks interrupts,
but line 186 above checks whether IF (Interrupt Flag) of EFLAGS saved
on kernel stack is disabled. Maybe on exception path, IF flag is
cleared first and the handler is called? CMIIW too
