6) Due to a couple convoluted error flows, it is possible for the CM to

likely that some of the recent changes have caused this issue to

If the CLEAN_SHUTDOWN flag is not set when a cache is loaded then all cache
blocks are marked as dirty and a full writeback occurs.
__commit_transaction() is responsible for setting/clearing
CLEAN_SHUTDOWN (based the flags_mutator that is passed in).
Fix this issue, of the cache's on-disk flags being wrong, by making sure
__commit_transaction() does not reset the flags after the mutator has
altered the flags in preparation for them being serialized to disk.
before:
sb_flags = mutator(le32_to_cpu(disk_super->flags));
disk_super->flags = cpu_to_le32(sb_flags);
disk_super->flags = cpu_to_le32(cmd->flags);
after:
disk_super->flags = cpu_to_le32(cmd->flags);
sb_flags = mutator(le32_to_cpu(disk_super->flags));

Commit 4c7e309340 ("dm btree remove: fix bug in redistribute3") wasn't
a complete fix for redistribute3().
The redistribute3 function takes 3 btree nodes and shares out the entries
evenly between them. If the three nodes in total contained
(MAX_ENTRIES * 3) - 1 entries between them then this was erroneously getting
rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 1) in
the center.
Fix this issue by being more careful about calculating the target number
of entries for the left and right nodes.

The patch adds the HWEQ function for the speaker output. User can set the
HWEQ parameters using the ALSA binary control byte-by-byte. We use the
following struct array to store the HWEQ parameters for implementing as
simple as possible.
struct rt5645_eq_param_s {
unsigned short reg;
unsigned short val;
};
It supports the variant length of the HWEQ parameters that are required.
We add the validating function in the function "rt5645_hweq_put" of the
ALSA binary control to avoid the user that puts the invalid parameters.
In the HWEQ enable function of speaker event, we also add the validating
function to prevent that the invalid parameters are applied to codec.
The HWEQ parameters should be controlled by DAPM for a specific sequence,
so the parameters will be applied to the codec in the speaker power up
event of DAPM, and will be disabled in the speaker power down event of
DAPM.

Mapping an image with a long parent chain (e.g. image foo, whose parent
is bar, whose parent is baz, etc) currently leads to a kernel stack
overflow, due to the following recursion in the reply path:
rbd_osd_req_callback()
rbd_obj_request_complete()
rbd_img_obj_callback()
rbd_img_parent_read_callback()
rbd_obj_request_complete()
...
Limit the parent chain to 16 images, which is ~5K worth of stack. When
the above recursion is eliminated, this limit can be lifted.

Currently we leak parent_spec and trigger a "parent reference
underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails.
The problem is we take the !parent out_err branch and that only drops
refcounts; parent_spec that would've been freed had we called
rbd_dev_unparent() remains and triggers rbd_warn() in
rbd_dev_parent_put() - at that point we have parent_spec != NULL and
parent_ref == 0, so counter ends up being -1 after the decrement.
Redo rbd_dev_probe_parent() to fix this.

Most of the changes this time are for incorrect device nodes in various
ways, on on imx, berlin, exynos, ux500, uniphier, omap and meson.
Chen-Yu Tsai now co-maintains mach-sunxi (Allwinner).
Other bug fixes include
* a partial revert of a broken tegra gpio patch
* irq affinity for arm ccn
* suspend on one Armada 385 machine
* enable ZONE_DMA to avoid an OMAP crash for over 2GB RAM
* turning on a regulator on beagleboard-x15 for HDMI
* making the omap gpmc debug code visible
* setup of orion network switch
* a rare build regression for pxa

of warnings. It was caused by the stack tracer triggering a warning
about using rcu_dereference() when RCU was not watching. This can happen
due to the fact that the stack tracer uses the function tracer to check
each function, and there's functions that may be called and traced
when RCU stopped watching. Namely when a function is called just before
going idle or to userspace and after RCU stopped watching that current
CPU.
The first patch makes sure that RCU is watching when the stack tracer
uses RCU. The second patch is to make sure that the stack tracer does
not get called by functions in NMI, as it's not NMI safe.

There is nothing to worry you much, only a few small & stable patches
are found for usual stuff, HD-audio (a Lenovo laptop quirk, a fix for
minor error handling) and ASoC (trivial fixes for RT298 and WM
codecs). The only remaining major change is the fix for ASoC SX_TLV
control that was overseen during refactoring, but the fix itself is
trivial and safe.
