do_double_faultRuns on an IST stack for x86_64 and on a special task stack for x86_32.* On x86_64, this is more or less a normal kernel entry. Notwithstanding the* SDM's warnings about double faults being unrecoverable, returning works as* expected
do_bounds
do_general_protection
math_errorNote that we play around with the 'TS' bit in an attempt to get* the correct behaviour even in the presence of the asynchronous* IRQ13 behaviour
