Pause the rx and make sure the rx fifo is empty when the autosuspend
occurs.
If the rx data comes when the driver is canceling the rx urb, the host
controller would stop getting the data from the device and continue
it after next rx urb is submitted. That is, one continuing data is
split into two different urb buffers. That let the driver take the
data as a rx descriptor, and unexpected behavior happens.

The XCOPY specification in SPC4r37 states that the XCOPY source and
destination device(s) should be derived from the copy source and copy
destination (CSCD) descriptor IDs in the XCOPY segment descriptor.
The CSCD IDs are generally (for block -> block copies), indexes into
the corresponding CSCD descriptor list, e.g.
=================================
EXTENDED COPY Header
=================================
CSCD Descriptor List
- entry 0
+ LU ID <--------------<------------------\
- entry 1 |
+ LU ID <______________<_____________ |
================================= | |
Segment Descriptor List | |
- segment 0 | |
+ src CSCD ID = 0 --------->---------+----/
+ dest CSCD ID = 1 ___________>______|
+ len
+ src lba
+ dest lba
=================================
Currently LIO completely ignores the src and dest CSCD IDs in the
Segment Descriptor List, and instead assumes that the first entry in the
CSCD list corresponds to the source, and the second to the destination.
This commit removes this assumption, by ensuring that the Segment
Descriptor List is parsed prior to processing the CSCD Descriptor List.
CSCD Descriptor List processing is modified to compare the current list
index with the previously obtained src and dest CSCD IDs.
Additionally, XCOPY requests where the src and dest CSCD IDs refer to
the CSCD Descriptor List entry can now be successfully processed.

There are only two reasons for xfs_log_force / xfs_log_force_lsn to fail:
one is an I/O error, for which xlog_bdstrat already logs a warning, and
the second is an already shutdown log due to a previous I/O errors. In
the latter case we'll already have a previous indication for the actual
error, but the large stream of misleading warnings from xfs_log_force
will probably scroll it out of the message buffer.

->total is a bit of an odd parameter passed down to the low-level
allocator all the way from the high-level callers. It's supposed to
contain the maximum number of blocks to be allocated for the whole
transaction [1].
But in xfs_iomap_write_allocate we only convert existing delayed
allocations and thus only have a minimal block reservation for the
current transaction, so xfs_alloc_space_available can't use it for
the allocation decisions. Use the maximum of args->total and the
calculated block requirement to make a decision. We probably should
get rid of args->total eventually and instead apply ->minleft more
broadly, but that will require some extensive changes all over.
[1] which creates lots of confusion as most callers don't decrement it
once doing a first allocation. But that's for a separate series.

We must decide in xfs_alloc_fix_freelist if we can perform an
allocation from a given AG is possible or not based on the available
space, and should not fail the allocation past that point on a
healthy file system.
But currently we have two additional places that second-guess
xfs_alloc_fix_freelist: xfs_alloc_ag_vextent tries to adjust the
maxlen parameter to remove the reservation before doing the
allocation (but ignores the various minium freespace requirements),
and xfs_alloc_fix_minleft tries to fix up the allocated length
after we've found an extent, but ignores the reservations and also
doesn't take the AGFL into account (and thus fails allocations
for not matching minlen in some cases).
Remove all these later fixups and just correct the maxlen argument
inside xfs_alloc_fix_freelist once we have the AGF buffer locked.

While in RUNNING state, phy_state_machine() checks for link changes by
comparing phydev->link before and after calling phy_read_status().
This works as long as it is guaranteed that phydev->link is never
changed outside the phy_state_machine().
If in some setups this happens, it causes the state machine to miss
a link loss and remain RUNNING despite phydev->link being 0.
This has been observed running a dsa setup with a process continuously
polling the link states over ethtool each second (SNMPD RFC-1213
agent). Disconnecting the link on a phy followed by a ETHTOOL_GSET
causes dsa_slave_get_settings() / dsa_slave_get_link_ksettings() to
call phy_read_status() and with that modify the link status - and
with that bricking the phy state machine.
This patch adds a fail-safe check while in RUNNING, which causes to
move to CHANGELINK when the link is gone and we are still RUNNING.

We make the bcm_sf2 driver override ds->ops which points to
b53_switch_ops since b53_switch_alloc() did the assignent. This is all
well and good until a second b53 switch comes in, and ends up using the
bcm_sf2 operations. Make a proper local copy, substitute the ds->ops
pointer and then override the operations.

There is no checking valid value of maxmtu when getting it from
device tree. This resolution added the checking condition to
ensure the assignment is made within a valid range.

A few fixes for 4.10.. the first fixes a long-standing logic bug, that
by luck (ie. size of packets written into RB for a submit) wasn't hit
on a3xx/a4xx but was causing intermittent GPU lockups on a5xx. And a
couple other robustness issues that Jordan noticed.
