There are some differences of mobile storage host between exynos3250
and exnos5250. For example, exynos3250 supports the HS400 mode, but
exynos5250 doesn't support it.
Since exynos3250 can perform the similar function with exynos5420
compatible, this patch changes the compatible from exynos5250 to
exynos5420 for mshc.

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));
disk_super->flags = cpu_to_le32(sb_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.

The PSCI specifications [1] and the SMC calling convention mandate
that unimplemented functions ids must return NOT_SUPPORTED (0xffffffff)
if a function id is called but it is not implemented.
Consequently, PSCI 1.0 function ids that require the 1.0 PSCI_FEATURES
call to be initialized:
CPU_SUSPEND (psci_init_cpu_suspend())
SYSTEM_SUSPEND (psci_init_system_suspend())
call the PSCI_FEATURES function id independently of the detected
PSCI firmware version, since, if the PSCI_FEATURES function id is not
implemented, it must return NOT_SUPPORTED according to the PSCI
specifications, causing the initialization functions to fail as expected.
Some existing PSCI implementations (ie Qemu PSCI emulation), do not
comply with the SMC calling convention and fail if function ids that are
not implemented are called from the OS, causing boot failures.
To solve this issue, this patch adds code that checks the PSCI firmware
version before calling PSCI 1.0 initialization functions so that the
OS makes sure that it is calling 1.0 functions only if the firmware
version detected is 1.0 or greater, therefore avoiding PSCI calls
that are bound to fail and might cause system boot failures owing
to non-compliant PSCI firmware implementations.

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.

Intel Wired LAN Driver Updates 2015-10-23
This series contains updates to i40e, i40evf, if_link, ixgbe and ixgbevf.
Anjali adds a workaround to drop any flow control frames from being
transmitted from any VSI, so that a malicious VF cannot send flow control
or PFC packets out on the wire. Also fixed a bug in debugfs by grabbing
the filter list lock before adding or deleting a filter.
Akeem fixes an issue where we were unconditionally returning VEB bridge
mode before allowing LB in the add VSI routine, resolve by checking if
the bridge is actually in VEB mode first.
Mitch fixed an issue where the incorrect structure was being used for
VLAN filter list, which meant the VLAN filter list did not get
processed correctly and VLAN filters would not be re-enabled after any
kind of reset.
Helin fixed a problem of possibly getting inconsistent flow control
status after a PF reset. The issue was requested_mode was being set
with a default value during probe, but the hardware state could be a
different value from this mode.
Carolyn fixed a problem where the driver output of the OEM version
string varied from the other tools.
Jean Sacren fixes up kernel documentation by fixing function header
comments to match actual variables used in the functions. Also
cleaned up variable initialization, when the variable would be
over-written immediately.
Hiroshi Shimanoto provides three patches to add "trusted" VF by adding
netlink directives and an NDO entry. Then implement these new controls
in ixgbe and ixgbevf. This series has gone through several iterations
to address all the suggested community changes and concerns.
