Another patch... I will post parts of it separately, if I am right
you should get 0xfe as the vector and a WARN from the gva_to_gpa function.
I confirm the vector is 0xfe, however I see no warnings from
gva_to_gpa() - only from emulate_exception():

I can see both warnings, if I move 'WARN(walker.fault.vector > 0x1f)'
from gva_to_gpa() to gva_to_gpa_nested(), however:
