[ Upstream commit 33f2c35a54dfd75ad0e7e86918dcbe4de799a56c ]
Due to a bug introduced in Linux 3.14 we cannot determine the
correctly layout for a multi-zone RAID0 array - there are two
possibilities.
It is possible to tell the kernel which to chose using a module
parameter, but this can be clumsy to use. It would be best if
the choice were recorded in the metadata.
So add a feature flag for this purpose.
If it is set, then the 'layout' field of the superblock is used
to determine which layout to use.
If this flag is not set, then mddev->layout gets set to -1,
which causes the module parameter to be required.

This reverts commit b145710b69388aa4034d32b4a937f18f66b5538e which is
commit 5d14c304bfc14b4fd052dc83d5224376b48f52f0 upstream.
The patch is not wrong, but the Fixes: tag is. It should have been:
Fixes: 060ad66f9795 ("dpaa_eth: change DMA device")
which means that it's fixing a commit which was introduced in:
git describe --tags 060ad66f97954
v5.4-rc3-783-g060ad66f9795
which then means it should have not been backported to linux-4.19.y,
where things _were_ working and now they're not.

commit 0c34bb598c510e070160029f34efeeb217000f8d upstream.
The removal of mips_swiotlb_ops exposed a problem in octeon_mgmt Ethernet
driver. mips_swiotlb_ops had an mb() after most of the operations and the
removal of the ops had broken the receive functionality of the driver.
My code inspection has shown no other places except
octeon_mgmt_rx_fill_ring() where an explicit barrier would be obviously
missing. The latter function however has to make sure that "ringing the
bell" doesn't happen before RX ring entry is really written.
The patch has been successfully tested on Octeon II.

commit 6bf6be1127f7e6d4bf39f84d56854e944d045d74 upstream.
Currently the system will be woken up via WOL(Wake On LAN) even if the
device wakeup ability has been disabled via sysfs:
cat /sys/devices/pci0000:00/0000:00:1f.6/power/wakeup
disabled
The system should not be woken up if the user has explicitly
disabled the wake up ability for this device.
This patch clears the WOL ability of this network device if the
user has disabled the wake up ability in sysfs.

Each iteration of for_each_child_of_node puts the previous node, but in
the case of a goto from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put under a new goto to put

Not sure nand_cleanup() is the right function to call here but in any
case it is not nand_release(). Indeed, even a comment says that
calling nand_release() is a bit of a hack as there is no MTD device to

comment.

[ Upstream commit 873a95e0d59ac06901ae261dda0b7165ffd002b8 ]
Currently we only poll for an ACT up to 30 times, with a busy-wait delay
of 100µs between each attempt - giving us a timeout of 2900µs. While
this might seem sensible, it would appear that in certain scenarios it
can take dramatically longer then that for us to receive an ACT. On one
of the EVGA MST hubs that I have available, I observed said hub
sometimes taking longer then a second before signalling the ACT. These
delays mostly seem to occur when previous sideband messages we've sent
are NAKd by the hub, however it wouldn't be particularly surprising if
it's possible to reproduce times like this simply by introducing branch
devices with large LCTs since payload allocations have to take effect on
every downstream device up to the payload's target.
So, instead of just retrying 30 times we poll for the ACT for up to 3ms,
and additionally use usleep_range() to avoid a very long and rude
busy-wait. Note that the previous retry count of 30 appears to have been
arbitrarily chosen, as I can't find any mention of a recommended timeout
or retry count for ACTs in the DisplayPort 2.0 specification. This also
goes for the range we were previously using for udelay(), although I
suspect that was just copied from the recommended delay for link
training on SST devices.
Changes since v1:
* Use readx_poll_timeout() instead of open-coding timeout loop - Sean
Paul
Changes since v2:
* Increase poll interval to 200us - Sean Paul
* Print status in hex when we timeout waiting for ACT - Sean Paul

commit 80e5f89da3ab949fbbf1cae01dfaea29f5483a75 upstream.
The command ring and cursor ring use different notify port addresses
definition: QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR. However, in
qxl_device_init() we use QXL_IO_NOTIFY_CMD to create both command ring
and cursor ring. This doesn't cause any problems now, because QEMU's
behaviors on QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR are the same.
However, QEMU's behavior may be change in future, so let's fix it.
P.S.: In the X.org QXL driver, the notify port address of cursor ring
is correct.

Commit 130f4caf145c ("libata: Ensure ata_port probe has completed before

Using async_synchronize_full() in PM callbacks is wrong, since async
callbacks that are already scheduled may wait for not-yet-scheduled
callbacks, causes a circular dependency.
Instead of using big hammer like async_synchronize_full(), use async
cookie to make sure port probe are synced, without affecting other
scheduled PM callbacks.

coccicheck reports:
drivers/md//bcache/btree.c:1538:1-7: preceding lock on line 1417
In btree_gc_coalesce func, if the coalescing process fails, we will goto
to out_nocoalesce tag directly without releasing new_nodes[i]->write_lock.
Then, it will cause a deadlock when trying to acquire new_nodes[i]->
write_lock for freeing new_nodes[i] before return.
btree_gc_coalesce func details as follows:
if alloc new_nodes[i] fails:
goto out_nocoalesce;
// obtain new_nodes[i]->write_lock
mutex_lock(&new_nodes[i]->write_lock)
// main coalescing process
for (i = nodes - 1; i > 0; --i)
[snipped]
if coalescing process fails:
// Here, directly goto out_nocoalesce
// tag will cause a deadlock
goto out_nocoalesce;
[snipped]
// release new_nodes[i]->write_lock
mutex_unlock(&new_nodes[i]->write_lock)
// coalesing succ, return
return;
out_nocoalesce:
btree_node_free(new_nodes[i]) // free new_nodes[i]
// obtain new_nodes[i]->write_lock
mutex_lock(&new_nodes[i]->write_lock);
// set flag for reuse
clear_bit(BTREE_NODE_dirty, &ew_nodes[i]->flags);
// release new_nodes[i]->write_lock
mutex_unlock(&new_nodes[i]->write_lock);
To fix the problem, we add a new tag 'out_unlock_nocoalesce' for
releasing new_nodes[i]->write_lock before out_nocoalesce tag. If
coalescing process fails, we will go to out_unlock_nocoalesce tag
for releasing new_nodes[i]->write_lock before free new_nodes[i] in
out_nocoalesce tag.

[ Upstream commit cc7eac1e4afdd151085be4d0341a155760388653 ]
Since EHCI/OHCI controllers on R-Car Gen3 SoCs are possible to
be getting stuck very rarely after a full/low usb device was
disconnected. To detect/recover from such a situation, the controllers
require a special way which poll the EHCI PORTSC register and changes
the OHCI functional state.
So, this patch adds a polling timer into the ehci-platform driver,
and if the ehci driver detects the issue by the EHCI PORTSC register,
the ehci driver removes a companion device (= the OHCI controller)
to change the OHCI functional state to USB Reset once. And then,
the ehci driver adds the companion device again.

[ Upstream commit 34d8673a01b053b6231a995a4eec9341163d63be ]
When running ntb_test, the script tries to run the ntb_perf test
immediately after probing the modules. Since adding multi-port support,
this fails seeing the new initialization procedure in ntb_perf
can not complete instantly.
To fix this we add a completion which is waited on when a test is
started. In this way, run can be written any time after the module is
loaded and it will wait for the initialization to complete instead of
sending an error.

Legacy drivers do not have port numbers (but is reliably only two ports)
and was broken by the recent commit that added mult-port support to
ntb_perf. This is especially important to support the cross link
topology which is perfectly symmetric and cannot assign unique port
numbers easily.
Hardware that returns zero for both the local port and the peer should
just always use gidx=0 for the only peer.

turns out was wrong. If the IOMMU is enabled, such alloctanions will
always fail with messages such as:
DMAR: Allocating domain for 0000:02:00.1 failed
This is because the IOMMU has not setup the device for such use.
Change the tools back to using the PCI device for allocations seeing
it doesn't make sense to add an IOMMU group for the non-physical NTB
device. Also remove the code that sets the DMA mask as it no longer
makes sense to do this.

[ Upstream commit 433efe720674efd9fdbcef78be75793393cf05db ]
Currently, ntb->dev is passed to dma_alloc_coherent
and dma_free_coherent calls. The returned dma_addr_t
is the CPU physical address. This works fine as long
as IOMMU is disabled. But when IOMMU is enabled, we
need to make sure that IOVA is returned for dma_addr_t.
So the correct way to achieve this is by changing the
first parameter of dma_alloc_coherent() as ntb->pdev->dev
instead.

[ Upstream commit 9d149045b3c0e44c049cdbce8a64e19415290017 ]
If the geneve interface is in collect_md (external) mode, it can't send any
packets submitted directly to its net interface, as such packets won't have
metadata attached. This is expected.
However, the kernel itself sends some packets to the interface, most
notably, IPv6 DAD, IPv6 multicast listener reports, etc. This is not wrong,
as tunnel metadata can be specified in routing table (although technically,
that has never worked for IPv6, but hopefully will be fixed eventually) and
then the interface must correctly participate in IPv6 housekeeping.
The problem is that any such attempt increases the tx_error counter. Just
bringing up a geneve interface with IPv6 enabled is enough to see a number
of tx_errors. That causes confusion among users, prompting them to find
a network error where there is none.
Change the counter used to tx_dropped. That better conveys the meaning
(there's nothing wrong going on, just some packets are getting dropped) and
hopefully will make admins panic less.
