This patch adds a "pci_bus_reset" option to the board_mode sysfs attribute.
This option uses the pci_reset_bus() api to reset the PCIe link the adapter
is on, which will reset the chip/adapter. Prior to issuing this option,
all functions on the same chip must be placed in the offline state by the
admin. After the reset, all of the instances may be brought online again.
The primary purpose of this functionality is to support cases where
firmware update required a chip reset but the admin did not want to reboot
the machine in order to instantiate the firmware update.
Sanity checks take place prior to the reset to ensure the adapter is the
sole entity on the PCIe bus and that all functions are in the offline
state.

When a target's link dropped, an RSCN was received to communicate the
change. The driver detected the loss of the target and issued and UNREG_RPI
mailbox command. While that was being processed, another RSCN was received
to communicate the port coming back. The driver deferred the PLOGI to the
port until the mailbox command finishes. When the mailbox command completed
it saw the pending port and called the routines to issue the
PLOGI. However, it forgot to clear the UNREG_INP state flag, so the PLOGI
xmt routine nooped the PLOGI request assuming it needed to wait for the
mailbox command. At this point, login would never be re-attempted.
Clear UNREG_INP before issuing the deferred PLOGI.

Currently, when a trunk link goes down due to some fault, the driver
snapshots the fault code. If the link then comes back up, meaning there is
no fault, the driver is not clearing the fault code so the sysfs link_state
entry reports old/stale data.
Revise the logic so that on successful link up the fault code is cleared.

64, before waiting for another event to indicate additional frame
reception. The net-net is this results in very slow frame processing during

With commit 09c2f95ad4 ("scsi: mpt3sas: Swap I/O memory read value back
to cpu endianness"), 64bit writes in _base_writeq() were rewritten to use
__raw_writeq() instad of writeq().
This introduced a bug apparent on powerpc64 systems such as the Raptor
Talos II that causes the HBA to drop from the PCIe bus under heavy load and
being reinitialized after a couple of seconds.
It can easily be triggered on affacted systems by using something like
fio --name=random-write --iodepth=4 --rw=randwrite --bs=4k --direct=0 \
--size=128M --numjobs=64 --end_fsync=1
fio --name=random-write --iodepth=4 --rw=randwrite --bs=64k --direct=0 \
--size=128M --numjobs=64 --end_fsync=1
a couple of times. In my case I tested it on both a ZFS raidz2 and a btrfs
raid6 using LSI 9300-8i and 9400-8i controllers.
The fix consists in resembling the write ordering of writeq() by adding a
mandatory write memory barrier before device access and a compiler barrier
afterwards. The additional MMIO barrier is superfluous.

The intent of invoking configfs_depend_item in commit 7474f52a82
("tcm_qla2xxx: Perform configfs depend/undepend for base_tpg")
was to prevent a physical Fibre Channel port removal when
virtual (NPIV) ports announced through that physical port are active.
The change does not work as expected: it makes enabled physical port
dependent on target configfs subsystem (the port's parent), something
the configfs guarantees anyway.
Besides, scheduling work in a worker thread and waiting for the work's
completion is not really a valid workaround for the requirement not to call
configfs_depend_item from a configfs callback: the call occasionally
deadlocks.
Thus, removing configfs_depend_item calls does not break anything and fixes
the deadlock problem.

The mvpp2_phylink_validate() sets all modes that are supported by a
given PPv2 port. An mistake made the 10000baseT_Full mode being
advertised in some cases when a port wasn't configured to perform at
10G. This patch fixes this.

This commit fix this and remove the old rule anyway.
Fixes: 35cc3cefc4 ("net/sched: cls_flower: Reject duplicated rules also under skip_sw")
