drivers being added but comparatively quiet on the core side with only
one big change going in and that a fairly straightforward refactoring.

 - Conversion of the array of DAI links to a list by Mengdong Lin,
   supporting dynamically adding and removing DAI links.
 - Some more fixes for the topology code, though it is still not final
   and ready for enabling in production.  We really need to get to the
   point where that can be done.
 - A pile of changes for Intel SkyLake drivers which hopefully deliver
   some useful initial functionality for systems with this chipset,
   though there is more work still to come.
 - New drivers for a number of Imagination Technologies IPs.
 - Lots of new features and cleanups for the Renesas drivers.
 - ANC support for WM5110.
 - New driver for Atmel class D speaker drivers.
 - New drivers for Cirrus CS47L24 and WM1831.
 - New driver for Dialog DA7128.
 - New drivers for Realtek RT5659 and RT56156.

Mengdong Lin [Wed, 6 Jan 2016 05:29:31 +0000 (13:29 +0800)] 
ASoC: Make aux_dev more like a generic component

aux_dev is mainly used by the machine driver to specify analog devices,
which are registered as codecs. Making it more like a generic component
can help the machine driver to use it to specify any component with
topology info by name.

Details:
- Remove the stub 'rtd_aux' array from the soc card.
- Add a list 'aux_comp_list' to store the components of aux_devs.
  And add a list head 'list_aux' to struct snd_soc_component, for adding
  such components to the above list.
- Add a 'init' ops to a component for machine specific init.
  soc_bind_aux_dev() will set it to be aux_dev's init. And it will be
  called when probing the component.
- soc_bind_aux_dev() will also search components by name of an aux_dev,
  since it may not be a codec.
- Move probing of aux_devs before checking new DAI links brought by
  topology.
- Move removal of aux_devs later than removal of links. Because topology
  of aux components may register DAIs and the DAI drivers will go with
  removal of the aux components, we want soc_remove_link_dais() to remove
  the DAIs at first.

Skylake sports new capability of DMA resume, DRSM where we can
resume the DMA. This capability is defined by presence of
AZX_DRSM_CAP_ID.

If this capability is present, we use this capability.
So we add:

snd_hdac_ext_stream_drsm_enable() - DMA resume caps
snd_hdac_ext_stream_set_dpibr() - set the DMA position
snd_hdac_ext_stream_set_lpib() - set the lpib

sctp: sctp should release assoc when sctp_make_abort_user return NULL in sctp_close

In sctp_close, sctp_make_abort_user may return NULL because of memory
allocation failure. If this happens, it will bypass any state change
and never free the assoc. The assoc has no chance to be freed and it
will be kept in memory with the state it had even after the socket is
closed by sctp_close().

So if sctp_make_abort_user fails to allocate memory, we should abort
the asoc via sctp_primitive_ABORT as well. Just like the annotation in
sctp_sf_cookie_wait_prm_abort and sctp_sf_do_9_1_prm_abort said,
"Even if we can't send the ABORT due to low memory delete the TCB.
This is a departure from our typical NOMEM handling".

But then the chunk is NULL (low memory) and the SCTP_CMD_REPLY cmd would
dereference the chunk pointer, and system crash. So we should add
SCTP_CMD_REPLY cmd only when the chunk is not NULL, just like other
places where it adds SCTP_CMD_REPLY cmd.

net, socket, socket_wq: fix missing initialization of flags

Commit ceb5d58b2170 ("net: fix sock_wake_async() rcu protection") from
the current 4.4 release cycle introduced a new flags member in
struct socket_wq and moved SOCKWQ_ASYNC_NOSPACE and SOCKWQ_ASYNC_WAITDATA
from struct socket's flags member into that new place.

Unfortunately, the new flags field is never initialized properly, at least
not for the struct socket_wq instance created in sock_alloc_inode().

One particular issue I encountered because of this is that my GNU Emacs
failed to draw anything on my desktop -- i.e. what I got is a transparent
window, including the title bar. Bisection lead to the commit mentioned
above and further investigation by means of strace told me that Emacs
is indeed speaking to my Xorg through an O_ASYNC AF_UNIX socket. This is
reproducible 100% of times and the fact that properly initializing the
struct socket_wq ->flags fixes the issue leads me to the conclusion that
somehow SOCKWQ_ASYNC_WAITDATA got set in the uninitialized ->flags,
preventing my Emacs from receiving any SIGIO's due to data becoming
available and it got stuck.

Make sock_alloc_inode() set the newly created struct socket_wq's ->flags
member to zero.

mm/vmstat: fix overflow in mod_zone_page_state()

mod_zone_page_state() takes a "delta" integer argument.  delta contains
the number of pages that should be added or subtracted from a struct
zone's vm_stat field.

If a zone is larger than 8TB this will cause overflows.  E.g.  for a
zone with a size slightly larger than 8TB the line

    mod_zone_page_state(zone, NR_ALLOC_BATCH, zone->managed_pages);

in mm/page_alloc.c:free_area_init_core() will result in a negative
result for the NR_ALLOC_BATCH entry within the zone's vm_stat, since 8TB
contain 0x8xxxxxxx pages which will be sign extended to a negative
value.

Fix this by changing the delta argument to long type.

This could fix an early boot problem seen on s390, where we have a 9TB
system with only one node.  ZONE_DMA contains 2GB and ZONE_NORMAL the
rest.  The system is trying to allocate a GFP_DMA page but ZONE_DMA is
completely empty, so it tries to reclaim pages in an endless loop.

This was seen on a heavily patched 3.10 kernel.  One possible
explaination seem to be the overflows caused by mod_zone_page_state().
Unfortunately I did not have the chance to verify that this patch
actually fixes the problem, since I don't have access to the system
right now.  However the overflow problem does exist anyway.

Given the description that a system with slightly less than 8TB does

mm: memcontrol: fix possible memcg leak due to interrupted reclaim

Memory cgroup reclaim can be interrupted with mem_cgroup_iter_break()
once enough pages have been reclaimed, in which case, in contrast to a
full round-trip over a cgroup sub-tree, the current position stored in
mem_cgroup_reclaim_iter of the target cgroup does not get invalidated
and so is left holding the reference to the last scanned cgroup.  If the
target cgroup does not get scanned again (we might have just reclaimed
the last page or all processes might exit and free their memory
voluntary), we will leak it, because there is nobody to put the
reference held by the iterator.

The problem is easy to reproduce by running the following command
sequence in a loop:

    mkdir /sys/fs/cgroup/memory/test
    echo 100M > /sys/fs/cgroup/memory/test/memory.limit_in_bytes
    echo $$ > /sys/fs/cgroup/memory/test/cgroup.procs
    memhog 150M
    echo $$ > /sys/fs/cgroup/memory/cgroup.procs
    rmdir test

The cgroups generated by it will never get freed.

This patch fixes this issue by making mem_cgroup_iter avoid taking
reference to the current position.  In order not to hit use-after-free
bug while running reclaim in parallel with cgroup deletion, we make use
of ->css_released cgroup callback to clear references to the dying
cgroup in all reclaim iterators that might refer to it.  This callback
is called right before scheduling rcu work which will free css, so if we
access iter->position from rcu read section, we might be sure it won't
go away under us.

the ct template.

Previously, ct_info.ct->general.use was initialized to 0 by
nf_ct_tmpl_alloc() and only incremented when ovs_ct_copy_action()

atomic_dec_and_test(ct_info.ct->general.use). This reference must be
incremented first, or nf_ct_put() will never free it.
