When HCI_Reset is issued the discovery state is assumed to be stopped.
The hci_cc_reset() handler was trying to set the state but it was doing
it without using the hci_discovery_set_state() function. Because of this
e.g. the mgmt Discovering event could go without being sent. This patch
fixes the code to use the hci_discovery_set_state() function instead of
just blindly setting the state value.

There's a check in set_secure_conn() that's supposed to ensure that SSP
is enabled before we try to request the controller to enable SC (since
SSP is a pre-requisite for it). However, this check only makes sense for
controllers actually supporting BR/EDR SC. If we have a 4.0 controller
we're only interested in the LE part of SC and should therefore not be
requiring SSP to be enabled. This patch adds an additional condition to
check for lmp_sc_capable(hdev) before requiring SSP to be enabled.

The btusb_disconnect() callback calls hci_unregister_dev() which in turn
calls btusb_close() if the HCI device is powered. The btusb_close()
function in turn will call btusb_free_frags(). It's therefore
unnecessary to have another call to btusb_free_frags() in the
btusb_disconnect() function. Besides the redundancy the second call
seems to also cause some strange stability issues which this patch then
also fixes.

When loading the Intel firmware it can happen that the firmware loading
complete vendor event arrives before the command complete event for the
last firmware fragment.
< HCI Command: Vendor (0x3f|0x0009) plen 7
01 02 fc 03 00 00 00
> HCI Event: Vendor (0xff) plen 5
06 00 00 00 00
> HCI Event: Command Complete (0x0e) plen 4
Vendor (0x3f|0x0009) ncmd 31
Status: Success (0x00)
This is mainly caused by the fact that the vendor command and its
command complete event are transported over the bulk endpoints. The
firmware loading complete event however is send over the interrupt
endpoint. So with just bad timing one event arrives before the other.
Currently the code does not account for it. There are precautions for
receiving firmware loading complete event quickly, but not for receiving
it before the command complete.
Introduce an extra flag that tracks when the firmware sending has
completed from the driver point of view and track the completion of
the firmware loading procedure with a different flag. That way the
wakeup can be handled properly.

The Intel Snowfield Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is connected via USB.
Snowfield Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.
Previous patches to the btusb driver allow overwriting the handling
for bulk receive endpoint packets and HCI events processing. The
firmware loading makes heavy use of these new internal callbacks.
This patch also introduces additional internal states to track if the
device is in bootloader or operational mode. This allows for correct
feedback about the firmware loading procedure.

disabled
Since commit f2c3c67f00 (merge commit that adds commit "ARM: mvebu:
completely disable hardware I/O coherency"), we disable I/O coherency
on Armada EBU platforms.
However, we continue to initialize the coherency fabric, because this
coherency fabric is needed on Armada XP for inter-CPU
coherency. Unfortunately, due to this, we also continued to execute
the coherency fabric initialization code for Armada 375/38x, which
switched the PL310 into I/O coherent mode. This has the effect of
disabling the outer cache sync operation: this is needed when I/O
coherency is enabled to work around a PCIe/L2 deadlock. But obviously,
when I/O coherency is disabled, having the outer cache sync operation
is crucial.
Therefore, this commit fixes the armada_375_380_coherency_init() so
that the PL310 is switched to I/O coherent mode only if I/O coherency
is enabled.
Without this fix, all devices using DMA are broken on Armada 375/38x.

This effectively reverts the last hunk of 392a9dad7e77 ("rbd: detect
when clone image is flattened").
The problem with parent_overlap != 0 condition is that it's possible
and completely valid to have an image with parent_overlap == 0 whose
parent state needs to be cleaned up on unmap. The next commit, which
drops the "clone image now standalone" logic, opens up another window
of opportunity to hit this, but even without it
# cat parent-ref.sh
#!/bin/bash
rbd create --image-format 2 --size 1 foo
rbd snap create foo@snap
rbd snap protect foo@snap
rbd clone foo@snap bar
rbd resize --allow-shrink --size 0 bar
rbd resize --size 1 bar
DEV=$(rbd map bar)
rbd unmap $DEV
leaves rbd_device/rbd_spec/etc and rbd_client along with ceph_client
hanging around.
My thinking behind calling rbd_dev_parent_put() unconditionally is that
there shouldn't be any requests in flight at that point in time as we
are deep into unmap sequence. Hence, even if rbd_dev_unparent() caused
by flatten is delayed by in-flight requests, it will have finished by
the time we reach rbd_dev_unprobe() caused by unmap, thus turning
unconditional rbd_dev_parent_put() into a no-op.

The comment for rbd_dev_parent_get() said
* We must get the reference before checking for the overlap to
* coordinate properly with zeroing the parent overlap in
* rbd_dev_v2_parent_info() when an image gets flattened. We
* drop it again if there is no overlap.
but the "drop it again if there is no overlap" part was missing from
the implementation. This lead to absurd parent_ref values for images
with parent_overlap == 0, as parent_ref was incremented for each
img_request and virtually never decremented.
Fix this by leveraging the fact that refresh path calls
rbd_dev_v2_parent_info() under header_rwsem and use it for read in
rbd_dev_parent_get(), instead of messing around with atomics. Get rid
of barriers in rbd_dev_v2_parent_info() while at it - I don't see what
they'd pair with now and I suspect we are in a pretty miserable
situation as far as proper locking goes regardless.

The fix from 9fc81d87420d ("perf: Fix events installation during
moving group") was incomplete in that it failed to recognise that
creating a group with events for different CPUs is semantically
broken -- they cannot be co-scheduled.
Furthermore, it leads to real breakage where, when we create an event
for CPU Y and then migrate it to form a group on CPU X, the code gets
confused where the counter is programmed -- triggered in practice
as well by me via the perf fuzzer.
Fix this by tightening the rules for creating groups. Only allow
grouping of counters that can be co-scheduled in the same context.
This means for the same task and/or the same cpu.

Currently ->get_dqblk() and ->set_dqblk() use struct fs_disk_quota which
tracks space limits and usage in 512-byte blocks. However VFS quotas
track usage in bytes (as some filesystems require that) and we need to
somehow pass this information. Upto now it wasn't a problem because we
didn't do any unit conversion (thus VFS quota routines happily stuck
number of bytes into d_bcount field of struct fd_disk_quota). Only if
you tried to use Q_XGETQUOTA or Q_XSETQLIM for VFS quotas (or Q_GETQUOTA
/ Q_SETQUOTA for XFS quotas), you got bogus results. Hardly anyone
tried this but reportedly some Samba users hit the problem in practice.
So when we want interfaces compatible we need to fix this.
We bite the bullet and define another quota structure used for passing
information from/to ->get_dqblk()/->set_dqblk. It's somewhat sad we have
to have more conversion routines in fs/quota/quota.c and another copying
of quota structure slows down getting of quota information by about 2%
but it seems cleaner than overloading e.g. units of d_bcount to bytes.

only if there were other writeable file descriptors. Fix the problem by

Currently CPTS is built into the netcp driver even though there is no
call out to the CPTS driver. This patch removes the dependency in Kconfig
and remove cpts.o from the Makefile for NetCP.

This patch fix is to use default firmware configuration files
present in the adapter incase if not available in standard
/lib/firmware/* dir. Additional cleanup is done to reuse flash
related defines from cxgb4 header file.
Please apply over net-next since it depends on previous commit.

====================
Mellanox ethernet driver updates Jan-27-2015
This patchset introduces some bug fixes, code cleanups and support in a new
firmware event called recoverable error events.
Patches were applied and tested against commit b8665c6 ("net: dsa/mv88e6352:
make mv88e6352_wait generic")
Changes from V0:
- Patch 6/11 ("net/mlx4_core: Fix struct mlx4_vhcr_cmd to make implicit padding
explicit"):
- Removed __packed
- Rephrased commit message
- Added a new patch by Majd ("net/mlx4_core: Update the HCA core clock frequency
after INIT_PORT")
====================

The firmware might change the hca core clock frequency after the driver
issues the INIT_PORT command. Therefore we need to query the new
value again and save in to the cached dev caps.
Fixes: ddd8a6c1 ('net/mlx4_core: Read HCA frequency and map internal clock')

We are dumping device capabilities which are supported both by the
firmware and the driver. Align the array that holds the capability
strings with this practice.

Fix a memory corruption at mlx4_MAD_IFC_wrapper.
A table of size dev->caps.pkey_table_len[port]*sizeof(*table)
was allocated, but get_full_pkey_table() assumes that the number
of entries in the table is a multiplication of 32 (which isn't always
correct).

Use cmd->autoneg as a user hint to decide what to set in ethtool set settings callback.
When cmd->autoneg == AUTONEG_ENABLE set according to ethtool->advertise otherwise,
set according to ethtool->speed.
Usage:
- ethtool -s eth<x> speed 56000 autoneg off
- ethtool -s eth<x> advertise 0x800000 autoneg on
While we're here:
- Move proto_admin masking outcome check to be adjacent to the operation.
- Move en_warn("port reset..") print to "port reset" block.

mlx4_bf_alloc had an unnecessary/duplicate code line. Did no harm,
but not good practice.

Struct mlx4_vhcr was implicitly padded by the gcc compiler on 64-bit
architectures.
This commit makes that padding explicit, to prevent issues with
changing compilers and with incompatibilities between 32-bit architecture
implicit padding and 64-bit architecture implicit padding.
This structure is used in virtualization for communication between
the Host and its Guests. The explicit padding allows 64-bit Hosts
(old and new) to continue to interoperate with 64-bit Guests (old and new).
However, without this fix, 64-bit Hosts could not interoperate with 32-bit
Guests (since these did not insert the padding dword). With this fix,
32-bit Guests will be able to interoperate with 64-bit Hosts (since
the structure offsets will be identical on both).

The driver incorrectly assigned an out-mailbox to this command,
and used an opcode modifier = 0, which is a reserved value (it
should use opcode modifier = 1).
