====================
Intel Wired LAN Driver Updates 2014-06-06
This series contains updates to i40e and i40evf.
Shannon sets the lan_veb index when the Virtual Ethernet Bridge (VEB) is
created for the basic LAN device and its Virtual Switch Interfaces (VSIs).
Also adds the VEB/VSI statistics in the ethtool stats output. Increases the
reset wait time because the original time was too optimistic and resets
were failing after EMPR. This won't delay the actual wait, just allows
us to poll more times as needed. He fixes the attempted removal of the
HMC space and unhook IRQs when a reset recovery fails because the HMC space
never got setup and IRQs are already unhooked in the first place, so the
removal is not necessary.
Jesse adds a log message for pre-production hardware so that the user is
notified that there may be issues with the hardware, yet does not prevent
the user from using the hardware. Add the printing of link messages
in the i40e driver like all the other Intel Ethernet drivers.
Mitch makes log message changes to i40evf to prevent confusion by making
the most common messages less scary by lowering them to a less terrifying
log level. This is due to the fact that depending on the timing of what
the PF driver is doing, it may take a few tries before the VF driver is able
to communicate with the PF driver on init or reset recovery.
Kamil provides a change to prevent the driver from getting into a endless
loop while trying to send GetVersion AQ command, since BO silicon blocks
AQ registers when in Blank Flash mode. So introduce a simple check for a
correct value in one of the AQ registers to be sure that AQ was configured
correctly.
Matt adds a function which indicates our intention to enable or disable a
particular transmit queue. Also adds a function to notify the device's
transmit unit that we are about to enable or disable a transmit queue.

This patch adds the following:
1) Compiler hinting in the fast path.
2) A prefetch of port->flags to eliminate moderate cpu stalling later
in mtip_hw_submit_io().
3) Eliminate a redundant rq_data_dir().
4) Reorder members of driver_data to eliminate false cacheline sharing
between irq_workers_active and unal_qdepth.
With some workload and topology configurations, I'm seeing ~1.5%
throughput improvement in small block random read benchmarks as well
as improved latency std. dev.

Avoid that closing /dev/infiniband/umad<n> or /dev/infiniband/issm<n>
triggers a use-after-free. __fput() invokes f_op->release() before it
invokes cdev_put(). Make sure that the ib_umad_device structure is
freed by the cdev_put() call instead of f_op->release(). This avoids
that changing the port mode from IB into Ethernet and back to IB
followed by restarting opensmd triggers the following kernel oops:

There is an errorneous case during the recovery like below.
In recovery_dentry,
1) dir = f2fs_iget();
2) mark the dir with FI_DELAY_IPUT
3) goto unmap_out
After the end of recovery routine, there is no dirty dentries so the dir cannot
be released by iput in remove_dirty_dir_inode.
This patch fixes such the bug case by handling the iget and iput in the
recovery_dentry procedure.

frequencies
MPU DPLL on OMAP5, DRA75x, DRA72x has a limitation on the maximum
frequency it can be locked at. Duty Cycle Correction circuit is used
to recover a correct duty cycle for achieving higher frequencies
(hardware internally switches output to M3 output(CLKOUTHIF) from M2
output (CLKOUT)).
So provide support to setup required data to handle Duty cycle by
the setting up the minimum frequency for DPLL. 1.4GHz is common
for all these devices and is based on Technical Reference Manual
information for OMAP5432((SWPU282U) chapter 3.6.3.3.1 "DPLLs Output
Clocks Parameters", and equivalent information from DRA75x, DRA72x

Use an extra state variable to keep track of when the IRQs are fully
set up. This keeps us from trying to unhook IRQs that already were
left unhooked in a failed reset recovery, e.g. when firmware is broken.

If a reset recovery failed (e.g. firmware is broken), the HMC space won't
get set up. We don't need to try to delete it if it didn't get set up.
This stops some needless error messages when we already know we need to
just tear things down.

The wait time was originally too optimistic and the resets were failing
after EMPR. This increases the loop count to wait considerably longer.
This won't delay the actual wait longer than really needed, just allows
us to poll more times as needed.

B0 Si blocks AQ registers when in Blank Flash mode - write is dropped,
read gives 0xDEADBEEF. Introduce a simple check for a correct value in one
of the AQ registers to be sure that AQ was configured correctly.
Without this check we get into an endless loop while trying to send
GetVersion AQ cmd.

Depending on the timing of what the PF driver is doing, it make take a
few tries before the VF driver is able to communicate with the PF driver
on init or reset recovery. In order to prevent confusion, make the most
common messages less scary by lowering them to a less terrifying log
level and indicate that the driver will retry.

Yoshihiro Yunomae reported that the ring buffer data for a trace
instance does not get properly cleaned up when it fails. He proposed
a patch that manually cleaned the data up and addad a bunch of labels.
The labels are not needed because all trace array is allocated with
a kzalloc which initializes it to 0 and all kfree()s can take a NULL
pointer and will ignore it.
Adding a new helper function free_trace_buffers() that can also take
null buffers to free the buffers that were allocated by
allocate_trace_buffers().

If tracing is disabled on boot up, the kernel should not execute tracing
self tests. The kernel should check whether tracing is disabled or not
before executing any of the tracing self tests.

ftrace_trace_arrays links global_trace.list. However, global_trace
is not added to ftrace_trace_arrays if trace_alloc_buffers() failed.
As the result, ftrace_trace_arrays becomes an empty list. If
ftrace_trace_arrays is an empty list, current top_trace_array() returns
an invalid pointer. As the result, the kernel can induce memory corruption
or panic.
Current implementation does not check whether ftrace_trace_arrays is empty
list or not. So, in this patch, if ftrace_trace_arrays is empty list,
top_trace_array() returns NULL. Moreover, this patch makes all functions
calling top_trace_array() handle it appropriately.

This patch fixes a OOPs where an attempt to write to the per-device
alua_access_state configfs attribute at:
/sys/kernel/config/target/core/$HBA/$DEV/alua/$TG_PT_GP/alua_access_state
results in an NULL pointer dereference when the backend device has not
yet been configured.
This patch adds an explicit check for DF_CONFIGURED, and fails with
-ENODEV to avoid this case.

This patch allows READ_CAPACITY + SAI_READ_CAPACITY_16 opcode
processing to occur while the associated ALUA group is in Standby
access state.
This is required to avoid host side LUN probe failures during the
initial scan if an ALUA group has already implicitly changed into
Standby access state.
This addresses a bug reported by Chris + Philip using dm-multipath
+ ESX hosts configured with ALUA multipath.
