Before attempting to activate a RAID array, it is checked for sufficient
redundancy. That is, we make sure that there are not too many failed
devices - or devices specified for rebuild - to undermine our ability to
activate the array. The current code performs this check twice - once to
ensure there were not too many devices specified for rebuild by the user
('validate_rebuild_devices') and again after possibly experiencing a failure
to read the superblock ('analyse_superblocks'). Neither of these checks are
sufficient. The first check is done properly but with insufficient
information about the possible failure state of the devices to make a good
determination if the array can be activated. The second check is simply
done wrong in the case of RAID10 because it doesn't account for the
independence of the stripes (i.e. mirror sets). The solution is to use the
properly written check ('validate_rebuild_devices'), but perform the check
after the superblocks have been read and we know which devices have failed.
This gives us one check instead of two and performs it in a location where
it can be done right.
Only RAID10 was affected and it was affected in the following ways:
- the code did not properly catch the condition where a user specified
a device for rebuild that already had a failed device in the same mirror
set. (This condition would, however, be caught at a deeper level in MD.)
- the code triggers a false positive and denies activation when devices in
independent mirror sets have failed - counting the failures as though they
were all in the same set.
The most likely place this error was introduced (or this patch should have
been included) is in commit 4ec1e369 - first introduced in v3.7-rc1.
Consequently this fix should also go in v3.7.y, however there is a
small conflict on the .version in raid_target, so I'll submit a
separate patch to -stable.

This change is meant to inline the Rx PTP descriptor handling. The main
motivation is to avoid unnecessary jumps into function calls that we then
immediately exit because we are not performing timestamps.
The net result of this change is that ixgbe_ptp_rx_tstamp drops from .5% CPU
utilization in my performance runs to 0%, and the only value tested is the Rx
descriptor which should already be warm in the cache if not stored in a
register.

This patch copies the igb implementation of Tx timestamps, which uses a work
item to poll for the Tx timestamp. In addition it adds a timeout value of 15
seconds, after which it will stop polling.
This is necessary due to an issue with the descriptor being marked done before
the Tx timestamp event has occurred. These two events don't correlate, so using
the done bit on the descriptor as indication that the timestamp must already
have been taken leads to potentially dropped Tx timestamps (especially under
heavy packet load)

This patch removes ixgbe_ptp_match, and the corresponding packet filtering from
ixgbe driver. This code was previously causing some issues within the hotpath of
the driver. However the code also provided a check against possible frozen Rx
timestamp due to dropped packets when the Rx ring is full. This patch provides a
replacement solution based on the watchdog.
To this end, whenever a packet consumes the Rx timestamp it stores the jiffy
value in the rx_ring structure. Watchdog updates its own jiffy timer whenever
there is no valid timestamp in the registers.
If watchdog detects a valid timestamp in the registers, (meaning that no Rx
packet has consumed it yet) it will check which time is most recent, the last
time in the watchdog, or any time in the rx_rings. If the most recent "event"
was more than 5seconds ago, it will flush the Rx timestamp and print a warning
message to the syslog.

This patch updates the filters for ethtool's get_ts_info to return support for
all filters which can be supported by upscaling to ptp_v2_event. The intent
behind this change is due to reasoning that we do in fact support the
filters. (hwtstamp_ioctl returns success after setting the filter to the
upscaled version). In this way we can remain consistent over which filters are
supported via the get_ts_info ioctl and which filters are in practice actually
supported.

This patch cleans up the ethtool diagnostics test by ensuring that the tests
work properly regardless of what state the adapter was in. The SRIOV VF check is
done at the beginning, forgoing the link test. The if_running -> dev_close is
moved before the link test, as well as a call to enable the Tx laser. This
ensures that the link test will return valid results even when adapter was
previously down. Also, a call to disable the Tx laser is added if the device
was down before the start. This ensures consistent behavior of the Tx laser
before and after the diagnostic checks. The end result is consistent behavior
regardless of device state.

This patch (as1643b) fixes a build error in ehci-hcd when compiling for

The fix is to convert ehci-mxc over to the new "ehci-hcd is a library"
scheme so that it can coexist peacefully with the ehci-platform
driver. As part of the conversion the ehci_mxc_priv data structure,
which was allocated dynamically, is now placed where it belongs: in

When posting a message on the bulletin board, the PF calculates crc
over the message and places the result in the message. When the VF
samples the Bulletin Board it copies the message aside and validates
this crc. The length of the message is crucial here and must be the
same in both parties. Since the PF is running in the Hypervisor and
the VF is running in a Vm, they can possibly be of different versions.
As the Bulletin Board is designed to grow forward in future versions,
in the VF the length must not be the size of the message structure
but instead it should be a field in the message itself.

In INTA mode, cnic and bnx2x share the same IRQ. During chip reset,
for example, cnic will stop servicing IRQs after it has shutdown the
cnic hardware resources. However, the shared IRQ is still active as
bnx2x needs to finish the reset. There is a window when bnx2x does
not know that cnic is no longer handling IRQ and things don't always
work properly.
Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set
before the first cnic IRQ is expected and cleared when no more cnic
IRQs are expected, so there should be no race conditions.

This was introduced in commit 6dccd16 "r8169: merge with version
6.001.00 of Realtek's r8169 driver". I did not find the version
6.001.00 online, but in 6.002.00 or any later r8169 from Realtek
this hunk is no longer present.
Also commit 05af214 "r8169: fix Ethernet Hangup for RTL8110SC
rev d" claims to have fixed this issue otherwise.
The magic compare mask of 0xfffe000 is dubious as it masks
parts of the Reserved part, and parts of the VLAN tag. But this
does not make much sense as the VLAN tag parts are perfectly
valid there. In matter of fact this seems to be triggered with
any VLAN tagged packet as RxVlanTag bit is matched. I would
suspect 0xfffe0000 was intended to test reserved part only.
Finally, this hunk is evil as it can cause more packets to be
handled than what was NAPI quota causing net/core/dev.c:
net_rx_action(): WARN_ON_ONCE(work > weight) to trigger, and
mess up the NAPI state causing device to hang.
As result, any system using VLANs and having high receive
traffic (so that NAPI poll budget limits rtl_rx) would result
in device hang.

Reverting 328d7b8 and instead adding an exception for the
Sierra Wireless MC7710.
commit 328d7b8 (net: cdc_mbim: send ZLP after max sized NTBs)
added a workaround for an issue observed on one specific device.
Concerns were raised that this workaround adds a performance
penalty to all devices based on questionable, if not buggy,
behaviour of a single device:
"If you add ZLP for NTBs of dwNtbOutMaxSize, you are heavily affecting CPU
load, increasing interrupt load by factor of 2 in high load traffic
scenario and possibly decreasing throughput for all other devices
which behaves correctly."
"The idea of NCM was to avoid extra ZLPs. If your transfer is exactly
dwNtbOutMaxSize, it's known, you can submit such request on the receiver
side and you do not need any EOT indicatation, so the frametime can be
used for useful data."
Adding a device specific exception to prevent the workaround from
affecting well behaved devices.
The assumption here is that needing a ZLP is truly an *exception*.
We do not yet have enough data to verify this. The generic
workaround in commit 328d7b8 should be considered acceptable despite
the performance penalty if the exception list becomes a maintainance
hassle.

Sometimes it is useful to be able to change the MAC address of the
interface for netback devices. For example, when using ebtables it may
be useful to be able to distinguish traffic from different interfaces
without depending on the interface name.

This reverts commit eccf2979b2c034b516e01b8a104c3739f7ef07d1.
The reason is that it broke TI WiLink shared transport on Panda.
Also, callback functions should not be added to board files anymore,
so revert to implementing the power functions in the driver itself.
Additionally, changed a variable name ('status' to 'err') so that this
revert compiles properly.

There are a number of bugs in the error paths of this driver. Make
use of devm_ functions to simplify the cleanup on error.

"The most important is a fix for a pciehp deadlock that occurs when
unplugging a Thunderbolt adapter. We also applied the same fix to
shpchp, removed CONFIG_EXPERIMENTAL dependencies, fixed a
pcie_aspm=force problem, and fixed a refcount leak.

The acpi core will call request_module("acpi-cpufreq") on subsystem init,
but this will fail if the module isn't available at that stage of boot.
Add some module aliases to ensure that udev can load the module on Intel
and AMD systems with the appropriate feature bits - I /think/ that this
will also work on VIA systems, but haven't verified that.
