Fix that by clearing the unused 32 high bits for all 32-bit ops\nexcept load/store which operate on tl values.\n\nReviewed-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\nSigned-off-by: Aurelien Jarno \u003caurelien@aurel32.net\u003e\nSigned-off-by: Richard Henderson \u003crth@twiddle.net\u003e\n",
