Further fix the file locking in the afs filesystem client in a number of
ways, including:

 (1) Don't submit the operation to obtain a lock from the server in a work
     queue context, but rather do it in the process context of whoever
     issued the requesting system call.

 (2) The owner of the file_lock struct at the front of the pending_locks
     queue now owns right to talk to the server.

 (3) Write locks can be instantly granted if they don't overlap with any
     other locks *and* we have a write lock on the server.

 (4) In the event of an authentication/permission error, all other matching
     pending locks requests are also immediately aborted.

 (5) Properly use VFS core locks_lock_file_wait() to distribute the server
     lock amongst local client locks, including waiting for the lock to
     become available.

Test with:

	sqlite3 /afs/.../scratch/billings.sqlite <<EOF
	CREATE TABLE hosts (
	    hostname varchar(80),
	    shorthost varchar(80),
	    room varchar(30),
	    building varchar(30),
	    PRIMARY KEY(shorthost)
	    );
	EOF

With the version of sqlite3 that I have, this should fail consistently with
EAGAIN, whether or not the program is straced (which introduces some delays
between lock syscalls).

Fix AFS file locking to allow fine grained locks as some applications, such
as firefox, won't work if they can't take such locks on certain state files
- thereby preventing the use of kAFS to distribute a home directory.

Note that this cannot be made completely functional as the protocol only
has provision for whole-file locks, so there exists the possibility of a
process deadlocking itself by getting a partial read-lock on a file first
and then trying to get a non-overlapping write-lock - but we got the
server's read lock with the first lock, so we're now stuck.

OpenAFS solves this by just granting any partial-range lock directly
without consulting the server - and hoping there's no remote collision.  I
want to implement that in a separate patch and it requires a bit more
thought.

In 2D transfers (for the AXI DMAC), the number of frames (numf) represents
Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful
for video transfers where screen resolutions ( X * Y ) are typically
aligned for X, but not for Y.

There is no requirement for Y_LENGTH to be aligned to the bus-width (or
anything), and this is also true for AXI DMAC.

Checking the Y_LENGTH for alignment causes false errors when initiating DMA
transfers. This change fixes this by checking only that the Y_LENGTH is
non-zero.

[ Upstream commit c7861adb ]

Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus.
But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC
are pointing towards the same internal PCS. Therefore nobody is
controlling the internal PCS of eTSEC0.

Upon initial ndo_open, the SGMII link is ok by virtue of U-boot
initialization. But upon an ifdown/ifup sequence, the code path from
ndo_open -> init_phy -> gfar_configure_serdes does not get executed for
the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII
link remains down for eTSEC0. On the LS1021A-TWR board, to signal this
failure condition, the PHY driver keeps printing
'803x_aneg_done: SGMII link is not ok'.

Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match
mdio1 device.

[ Upstream commit 7893f9e1 ]

Some tcpc device-drivers need to explicitly be told to watch for connection
events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices
being plugged into the Type-C port will not be noticed.

For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to
watch for connection events. Sofar we lack a similar callback to the tcpc
for single-role ports. With some tcpc-s such as the fusb302 this means
no TCPM_CC_EVENTs will be generated when the port is configured as a
single-role port.

This commit renames start_drp_toggling to start_toggling and since the
device-properties are parsed by the tcpm-core, adds a port_type parameter
to the start_toggling callback so that the tcpc_dev driver knows the
port-type and can act accordingly when it starts toggling.

The new start_toggling callback now always gets called if defined, instead
of only being called for DRP ports.

To avoid this causing undesirable functional changes all existing
start_drp_toggling implementations are not only renamed to start_toggling,
but also get a port_type check added and return -EOPNOTSUPP when port_type
is not DRP.

[ Upstream commit 1a2391c3 ]

The rxrpc packet serial number cannot be safely used to compute out of
order ack packets for several reasons:

 1. The allocation of serial numbers cannot be assumed to imply the order
    by which acks are populated and transmitted.  In some rxrpc
    implementations, delayed acks and ping acks are transmitted
    asynchronously to the receipt of data packets and so may be transmitted
    out of order.  As a result, they can race with idle acks.

 2. Serial numbers are allocated by the rxrpc connection and not the call
    and as such may wrap independently if multiple channels are in use.

In any case, what matters is whether the ack packet provides new
information relating to the bounds of the window (the firstPacket and
previousPacket in the ACK data).

Fix this by discarding packets that appear to wind back the window bounds
rather than on serial number procession.

[ Upstream commit e0a7683d ]

The Credit Based Shaper heavily depends on link speed to calculate
the scheduling credits, we can't properly calculate the credits if the
device has failed to report the link speed.

In that case we can't dequeue packets assuming a wrong port rate that will
result into an inconsistent credit distribution.

This patch makes sure we fail to dequeue case:

1) __ethtool_get_link_ksettings() reports error or 2) the ethernet driver
failed to set the ksettings' speed value (setting link speed to
SPEED_UNKNOWN).

Additionally we properly re calculate the port rate whenever the link speed
is changed.

When CONFIG_OF_OVERLAY is not enabled the fallback stub for
of_overlay_fdt_apply() does not match the prototype for the case when
CONFIG_OF_OVERLAY is enabled. Update the stub to use the correct
function prototype.

If module initialization fails after the character device has been
registered, unregister the character device. Additionally, avoid
duplicating error path code.

[ Upstream commit 1fbd20f8 ]

check_stack_access() that prints verbose log is used in
adjust_ptr_min_max_vals() that prints its own verbose log and now they
stick together, e.g.:

  variable stack access var_off=(0xfffffffffffffff0; 0x4) off=-16
  size=1R2 stack pointer arithmetic goes out of range, prohibited for
  !root

Add missing newline so that log is more readable:
  variable stack access var_off=(0xfffffffffffffff0; 0x4) off=-16 size=1
  R2 stack pointer arithmetic goes out of range, prohibited for !root

[ Upstream commit 24db953e ]

The IRQ mapping was changed to not being created in the rtc-mt6397
driver, so the irq_dispose_mapping is no longer needed.
Also the dev_id passed to free_irq should be the same as the last
argument passed to request_threaded_irq.
This prevents a "Trying to free already-free IRQ 274" warning when
unbinding the driver.
