4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Michael Holzheu <[email protected]> commit 3c8e5105e759e7b2d88ea8a85b1285e535bc7500 upstream. The REGSET_VX_LOW ELF notes should contain the lower 64 bit halfes of the first sixteen 128 bit vector registers. Unfortunately currently we copy the upper halfes. Fix this and correctly copy the lower halfes.
