Firmware dump feature is added for PCIe based chipsets which can
be used with the help of ethtool commands.
1) Trigger firmware dump operation:
ethtool --set-dump mlan0 0xff
When the operation is completed, udev event will be sent to
trigger external application.
2) Following udev rule can be used to get the data from ethtool:
DRIVER=="mwifiex_pcie", ACTION=="change", RUN+="/sbin/mwifiex_pcie_fw_dump.sh"
mwifiex_pcie_fw_dump.sh: #!/bin/bash
ethtool --set-dump mlan0 0
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/ITCM.log
ethtool --set-dump mlan0 1
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/DTCM.log

race condition that happens between enabling/disabling syscall tracepoints
and new process creations (the check to go into the ptrace path for a process
can be set when it shouldn't, or not set when it should). Not a major bug
but one that should be fixed and even applied to stable.
The other two patches are cleanup/fixes that are not that critical, but
for an -rc1 release would be nice to have. They both deal with syscall
tracepoints.
It also includes a patch to introduce a new macro for the TRACE_EVENT()
format called __field_struct(). Originally, __field() was used to record
any variable into a trace event, but with the addition of setting the
"is signed" attribute, the check causes anything but a primitive variable
to fail to compile. That is, structs and unions can't be used as they
once were. When the "is signed" check was introduce there were only
primitive variables being recorded. But that will change soon and it
was reported that __field() causes build failures.
To solve the __field() issue, __field_struct() is introduced to allow
trace_events to be able to record complex types too.

Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.
This allows optimization of size of the command, which may be

new version correctly, even if they don't (yet) make use of the

The commit 71ec7c55ed introduced the magic symbol ".TOC." for ELFv2 ABI.
This symbol is built manually and has no CRC value computed. A zero value
is put in the CRC section to avoid modpost complaining about a missing CRC.
Unfortunately, this breaks the kernel module loading when the kernel is
relocated (kdump case for instance) because of the relocation applied to
the kcrctab values.
This patch compute a CRC value for the TOC symbol which will match the one
compute by the kernel when it is relocated - aka '0 - relocate_start' done in
maybe_relocated called by check_version (module.c).

In commit 27f4488872 "Add OPAL takeover from PowerVM" we added support
for "takeover" on OPAL v1 machines.
This was a mode of operation where we would boot under pHyp, and query
for the presence of OPAL. If detected we would then do a special
sequence to take over the machine, and the kernel would end up running
in hypervisor mode.
OPAL v1 was never a supported product, and was never shipped outside
IBM. As far as we know no one is still using it.
Newer versions of OPAL do not use the takeover mechanism. Although the
query for OPAL should be harmless on machines with newer OPAL, we have
seen a machine where it causes a crash in Open Firmware.
The code in early_init_devtree() to copy boot_command_line into cmd_line
was added in commit 817c21ad9a "Get kernel command line accross OPAL
takeover", and AFAIK is only used by takeover, so should also be
removed.

When a Tx hang happens, usually the Tx queue disable fails. At
this point if we try to recover by a VSI reinit the HW gets
unhappy and we get a Malicious Driver Detect (MDD) event.
HW expects a PF reset if a queue disable fails, if we don't do a PF
reset and restart the queue we get an MDD. This patch makes sure we
do a PF reset on Tx hang and that way we avoid any MDD because of Tx
queue disable failure.

Don't short-circuit the LAA assignment when the driver thinks it has
already been done - it is possible that the user might want to force
the address setting again. At the same time, this requires a little
re-ordering of the filter management.

Make sure the Firmware sets up the LAA as a Wake-On-LAN address.

The ability is already there in the fw and this will make it easy
to toggle link without calling set_phy_config when no other link
settings need to change.

This patch fixes the i40e_set_coalesce function to allow 0 as a disable
value. Also, added message to user about invalid value and provides valid
range.

This log print message will probably never be seen, but it needs to match
the "attempting to rebuild switch\n" log message a few lines above.

If the firmware's API minor number is larger than the one expected, log
a warning and recommend driver SW update.
If the firmware's API major or minor number is smaller then the one expected
(n for major, n or n-1 for minor), log a warning and recommend NVM update.

As per the spec when the PF driver receives a Malicious driver event
the queue that caused the event is already stopped and it is expected
that the function that owns the queue will reset the queue.
In some cases it may not be possible to determine the queue and it is
suggested to reset the whole function.
This patch takes the later approach when the event is owned by the PF
that owns it.

The return from i40e_prep_for_reset() was being ignored by almost all
its callers. The one place it wasn't ignored could have caused a silent
and confusing failure of the driver to finish a reset. Since we really
are doing a rebuild anyway, ignore this last case as well and simply
make the function a void type.

If the host VMM administrator has changed the VF device's MAC address then
the i40e driver needs to halt the VF device so that the administrator will
be forced to reload the VF driver. This will cause the VF driver to start
using the newly assigned MAC address. This brings the i40e driver into
conformance with operational characteristics of other Intel SR-IOV
featured drivers.

Fix nfs4_negotiate_security to create an rpc_clnt used to test each SECINFO
returned pseudoflavor. Check credential creation (and gss_context creation)
which is important for RPC_AUTH_GSS pseudoflavors which can fail for multiple
reasons including mis-configuration.
Don't call nfs4_negotiate in nfs4_submount as it was just called by
nfs4_proc_lookup_mountpoint (nfs4_proc_lookup_common)

Do not return RPC_AUTH_UNIX if SEINFO reply tests fail. This
prevents an infinite loop of NFS4ERR_WRONGSEC for non RPC_AUTH_UNIX mounts.
Without this patch, a mount with no sec= option to a server
that does not include RPC_AUTH_UNIX in the
SECINFO return can be presented with an attemtp to use RPC_AUTH_UNIX
which will result in an NFS4ERR_WRONG_SEC which will prompt the SECINFO
call which will again try RPC_AUTH_UNIX....

Now that we have functions such as nfs_write_pageuptodate() that use
the cache_validity flags to check if the data cache is valid or not,
it is a little more important to keep the flags in sync with the
state of the data cache.
In particular, we'd like to ensure that if the data cache is empty, we
don't start marking it as needing revalidation.
