From 2c7a81c60df147a14735ca3c0f039cf4507b65fc Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Thu, 11 Jun 2015 19:59:04 +0200 Subject: s390/kdump: fix REGSET_VX_LOW vector register ELF notes 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.
