Title:
SECURITY_SELINUX_DISABLE should be enable on X s390x
Status in QA Regression Testing:

Bug description:
== SRU Justification ==
Security team requires the CONFIG_SECURITY_SELINUX_DISABLE should be
enabled in all of our kernels.
Currently it's not enabled for s390x in Xenial. And causing the
test_081_config_security_selinux_disable test in ubuntu_kernel_security
test suite complaining about this:
======================================================================
FAIL: test_081_config_security_selinux_disable
(__main__.KernelSecurityConfigTest)
Ensure CONFIG_SECURITY_SELINUX_DISABLE is disabled (LP: #1680315)
----------------------------------------------------------------------
Traceback (most recent call last):
File "./test-kernel-security.py", line 2158, in
test_081_config_security_selinux_disable
self.assertKernelConfig('SECURITY_SELINUX_DISABLE', expected)
File "./test-kernel-security.py", line 207, in assertKernelConfig
self.assertKernelConfigSet(name)
File "./test-kernel-security.py", line 194, in assertKernelConfigSet
'%s option was expected to be set in the kernel config' % name)
AssertionError: SECURITY_SELINUX_DISABLE option was expected to be set in
the kernel config
== Test ==
A test kernel could be found here:
https://people.canonical.com/~phlin/kernel/lp-1813721-s390x-selinux/
This issue can be verified with a q-r-t test:
test_081_config_security_selinux_disable, the test will pass with the
patched kernel.
test_081_config_security_selinux_disable (__main__.KernelSecurityConfigTest)
Ensure CONFIG_SECURITY_SELINUX_DISABLE is disabled (LP: #1680315) ...
(skipped: l) ok
== Regression Potential ==
Low, we already have this config enabled in all kernels except this
specific Xenial s390x.
