Ahem, but let me note before somebody else does: it isn't interrupt context,
it is normal process context - while an interrupt can ignore most of the
thread_info fields, a normal process has to worry about all 9. To be on the
safe side, the first 8 need to be copied into and out of the ndis stack, with
preempt disabled until after the stack switch.
