STATUS_INSUFFICIENT_RESOURCES (BZ#1767621)

* Since RHEL commit 5330f5d09820 high load can cause dm-multipath path
failures (BZ#1770113)

* Hard lockup in free_one_page()->_raw_spin_lock() because sosreport
command is reading from /proc/pagetypeinfo (BZ#1770732)

* fix compat statfs64() returning EOVERFLOW for when _FILE_OFFSET_BITS=64
(BZ#1775678)

* Guest crash after load cpuidle-haltpoll driver (BZ#1776289)

* RHEL 7.7 long I/O stalls with bnx2fc from not masking off scope bits of
retry delay value (BZ#1776290)

* Multiple "mv" processes hung on a gfs2 filesystem (BZ#1777297)

* Moving Egress IP will result in conntrack sessions being DESTROYED
(BZ#1779564)

* core: backports from upstream (BZ#1780033)

* kernel BUG at arch/powerpc/platforms/pseries/lpar.c:482! (BZ#1780148)

* Race between tty_open() and flush_to_ldisc()  using the
tty_struct->driver_data field. (BZ#1780163)
