Instead of using __pa which is meant to be a general function for converting virtual addresses to physical addresses we can use __pa_symbol which is the preferred way of decoding kernel text virtual addresses to physical addresses.
In this case we are not directly converting C visible symbols however if we know that the instruction pointer is somewhere between _text and _etext we know that we are going to be translating an address form the kernel text space.
