[Greg Kroah-Hartman]

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

Fixes the backport of 0b34a166f291d255755be46e43ed5497cdd194f2 upstream

Commit 0b34a166f291d255755be46e43ed5497cdd194f2 "x86/xen: Support
kexec/kdump in HVM guests by doing a soft reset" has been added to the
4.2-stable tree" needed to correct the CONFIG variable, as
CONFIG_KEXEC_CORE only showed up in 4.3.
