MIPS: Update trap codes
Add a few missing trap codes. [ralf@linux-mips.org: Drop removal of exception codes. I don't care what the incomplete architecture spec says; it can't change existing hardware and VCEI is supported indeed.] Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Gleb Natapov <gleb@kernel.org> Cc: kvm@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/11890/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
