[Qemu-devel] [PATCH v4 6/8] target/ppc: simplify VEXT_SIGNED macro in int_helper.c

[Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>]

As pointed out by Richard: it does not need the mask argument, nor does it need
the recast argument. The masking is implied by the cast argument, and the
recast is implied by the assignment.
