request_module for w1 slave modules needs to be called with the w1
master mutex unlocked. Because w1_attach_slave_device gets always(?)
called with mutex locked, we need to temporarily unlock the w1 master
mutex for the loading of the w1 slave module.

Introduce a check to make sure that fops are only called if they have
been defined by the slave module.
Without this check modules like w1_smem cause a NULL pointer dereference
bug.

Do not send SMB2 Logoff command when reconnecting, the way smb1

Also, no need to wait for a credit for an echo command when one is already

Without these changes, umount command hangs if the server is unresponsive

This patch fixes the tclk frequency array for the Armada-370 SoC.
This bug has been introduced by commit 6b72333d
("clk: mvebu: add Armada 370 SoC-centric clock init").
A wrong tclk frequency affects the following drivers: mvsdio, mvneta,
i2c-mv64xxx and mvebu-devbus. This list may be incomplete.
About the mvneta Ethernet driver, note that the tclk frequency is used
to compute the Rx time coalescence. Then, this bug harms the coalescence
configuration and also degrades the networking performances with the
default values.

Pull SCSI target fixes from Nicholas Bellinger:
"Here are the outstanding target fixes queued up for v3.12-rc4 code.
The highlights include:
- Make vhost/scsi tag percpu_ida_alloc() use GFP_ATOMIC
- Allow sess_cmd_map allocation failure fallback to use vzalloc
- Fix COMPARE_AND_WRITE se_cmd->data_length bug with FILEIO backends
- Fixes for COMPARE_AND_WRITE callback recursive failure OOPs + non
zero scsi_status bug
- Make iscsi-target do acknowledgement tag release from RX context
- Setup iscsi-target with extra (cmdsn_depth / 2) percpu_ida tags
Also included is a iscsi-target patch CC'ed for v3.10+ that avoids
legacy wait_for_task=true release during fast-past StatSN
acknowledgement, and two other SRP target related patches that address
long-standing issues that are CC'ed for v3.3+.

When the all LE connections have been disconneted, then it is up to
the host to re-enable advertising at that point. To ensure that the
correct advertising parameters are used, force the usage of the
common helper to enable advertising.

event handler into the management core so that the helper can

The LE advertising parameters can only be modified when advertising
is disabled. So before enabling it, make sure the controller has all
the right parameters.
Right now all default values are used and thus this does no change
any existing behavior. One minor exception is that in case of single
mode LE-only controllers without a public address, now the random
address is used for advertising.

In case of a single mode LE-only controller it is possible that no
public address is used. These type of controllers require a random
address to be configured.
Without a configured static random address, such a controller is
not functional. So reject powering on the controller in this case
until it gets configured with a random address.
The controller setup stage is still run since it is the only way
to determinate if a public address is available or not. So it is
similar on how RFKILL gets handled during initial setup of the
controller.

There are two defined HCI device types. One is for BR/EDR controllers
and the other is for AMP controllers. The HCI device type is not the
same as the AMP controller type. It just happens that currently the
defined types match, but that is not guaranteed.

Windows 8 and later can create NFS symlinks (within reparse points)
which we were assuming were normal NTFS symlinks and thus reporting
corrupt paths for. Add check for reparse points to make sure that
they really are normal symlinks before we try to parse the pathname.
We also should not be parsing other types of reparse points (DFS
junctions etc) as if they were a symlink so return EOPNOTSUPP
on those. Also fix endian errors (we were not parsing symlink
lengths as little endian).
This fixes commit d244bf2dfbebfded05f494ffd53659fa7b1e32c1

LE controllers will automatically disable advertising whenever they
accept a new connection. In order not to fall out of sync with the
advertising setting we need to re-enable advertising whenever the last
LE connection drops. A failure to re-enable advertising should cause the
setting to be disabled, so this patch also calls mgmt_new_settings()
when this happens.

A function is needed so that the HCI event processing can ask the mgmt
code to emit a new settings event. This is necessary e.g. when the event
processing does updates to mgmt related states without any dependency of
actual mgmt commands.

Pull CIFS fixes from Steve French:
"Small set of cifs fixes. Most important is Jeff's fix that works
around disconnection problems which can be caused by simultaneous use
of user space tools (starting a long running smbclient backup then
doing a cifs kernel mount) or multiple cifs mounts through a NAT, and
Jim's fix to deal with reexport of cifs share.
I expect to send two more cifs fixes next week (being tested now) -
fixes to address an SMB2 unmount hang when server dies and a fix for
cifs symlink handling of Windows "NFS" symlinks"
* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
[CIFS] update cifs.ko version
[CIFS] Remove ext2 flags that have been moved to fs.h
[CIFS] Provide sane values for nlink
cifs: stop trying to use virtual circuits
CIFS: FS-Cache: Uncache unread pages in cifs_readpages() before freeing them

Pull PCI fix from Bjorn Helgaas:
"We merged what was intended to be an MMCONFIG cleanup, but in fact,
for systems without _CBA (which is almost everything), it broke
extended config space for domain 0 and it broke all config space for
other domains.
This reverts the change"
* tag 'pci-v3.12-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
Revert "x86/PCI: MMCONFIG: Check earlier for MMCONFIG region at address zero"

Recognise the new Packet Memory and RX Data Path counters.
The following counters are added:
rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed. This should not
occur if BB correctly configured.
rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory. May
indicate RX performance problems.
rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism.
Since Qbb is not supported at present, this should not occur.
rx_pm_discard_mapping - 802.1p priority configured to be dropped. This should
not occur in normal operation.
rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is
disabled. May indicate misconfiguration by the driver.
rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be
dropped.
rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a
filter directed the packet to the MCPU.
rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be
loaded. Indicates performance problems but not drops.
These are only provided if the MC firmware has the
PM_AND_RXDP_COUNTERS capability. Otherwise, mask them out.
