commit 04be64dc8a08203decc6fe206700dcb1f06c8d79
Author: Nathan Scott <nathans@redhat.com>

pmdalinux: fix interrupts file parser for s390x /proc/interrupts layout
The s390x interrupts file produced by the kernel was causing a failure
in pmdalinux because the code expected first numeric interrupt lines &
then named (text) lines, whereas on this platform they're intermixed.
Add a sample interrupts file from these kernels for qa/886 to test.
Resolves Red Hat BZ #1798058
