Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The following upstream
stable patches should be included in the Ubuntu kernel:
v4.4.244 upstream stable release
from git://git.kernel.org/
ring-buffer: Fix recursion protection transitions between interrupt context
gfs2: Wake up when sd_glock_disposal becomes zero
mm: mempolicy: fix potential pte_unmap_unlock pte error

perf tools: Add missing swap for ino_generation
ALSA: hda: prevent undefined shift in snd_hdac_ext_bus_get_link()

x86/speculation: Allow IBPB to be conditionally enabled on CPUs with always-on
STIBP
xen/events: avoid removing an event channel while handling it
xen/events: add a proper barrier to 2-level uevent unmasking
xen/events: fix race in evtchn_fifo_unmask()
xen/events: add a new "late EOI" evtchn framework
xen/blkback: use lateeoi irq binding
xen/netback: use lateeoi irq binding
