(CVE-2019-13272)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Bug Fix(es):

* [kernel-alt]: BUG: unable to handle kernel NULL pointer IP:
crypto_remove_spawns+0x118/0x2e0 (BZ#1536967)

* [HPE Apache] update ssif max_xmit_msg_size limit for multi-part messages
(BZ#1610534)

* RHEL-Alt-7.6 - powerpc/pseries: Fix unitialized timer reset on migration
/ powerpc/pseries/mobility: Extend start/stop topology update scope (LPM)
(BZ#1673613)
