This whole thing would be a -lot- easier to do from C code. Why ?  
Simply
because you could just use get_user() to load the instruction rather
than doing this page table walking in asm,

Just be careful the get_user() doesn't regenerate the same
translation error you are trying to fix by being here......
It is nice doing things in C code, but you have to be aware
of the environment and the side effects when in this kind
of exception state.

Thanks.
