Error log:
arch/alpha/kernel/traps.c: In function 'do_entIF':
arch/alpha/kernel/traps.c:373:35: error: too few arguments to function 'alpha_fp_emul'
  373 |                         si_code = alpha_fp_emul(regs->pc - 4);

This affects v5.15.221,  v6.1.188, and v6.6.157.

$ git log --oneline v5.15.220.. arch/alpha/kernel/traps.c arch/alpha/math-emu/math.c
f55e039ce84f alpha: don't leak hardware-fabricated FP exception bits to user space

is the culprit. One of the calls to alpha_fp_emul() was not updated to add
the second argument.
