UserGenException argument passing (PR 43431)

[Martin Husemann <martin%duskware.de@localhost>]

Hi folks,

could someone please explain how UserGenException (arch/mips/mips/mipsX_subr.S)
is supposed to pass the last argument (the trap frame pointer) to trap()?

Especially why there is no ifdef for o32 vs. n{32,64}, like at other call
sites? I would expect n32/n64 to pass the pointer in A4 instead of the stack.
