The IOMMU driver now looks for the "mediatek,infracfg" phandle as a
new way to retrieve a syscon to that:
even though the old way is retained, it has been deprecated and the
driver will write a message in kmsg advertising to use the phandle
way instead.
For this reason, assign the right phandle to mediatek,infracfg in
the iommu node.

The entry-method property of the idle-states node should be "psci" as
described in the idle-states binding, since this is already the value of
enable-method in the CPU nodes. Fix it to get rid of a dtbs_check

Tweak the name of the idle-states subnodes so that they follow the
binding pattern, getting rid of dtbs_check warnings.
Only the usage of "-" in the name was necessary, but "off" was also
exchanged for "sleep" since that seems to be a more common wording in
other dts files.

Pull 9pfs fixes from Dominique Martinet:
"A couple of fid refcount and fscache fixes:
- fid refcounting was incorrect in some corner cases and would leak
resources, only freed at umount time. The first three commits fix
three such cases
- 'cache=loose' or fscache was broken when trying to write a partial
page to a file with no read permission since the rework a few
releases ago.
The fix taken here is just to restore old behavior of using the
special 'writeback_fid' for such reads, which is open as root/RDWR
and such not get complains that we try to read on a WRONLY fid.
Long-term it'd be nice to get rid of this and not issue the read at
all (skip cache?) in such cases, but that direction hasn't
progressed"

vxge-main.c"
This reverts commit 8fc74d18639a2402ca52b177e990428e26ea881f.
BAR0 is the main (only?) register bank for this device. We most
obviously can't unmap it before the netdev is unregistered.
This was pointed out in review but the patch got reposted and
merged, anyway.
The author of the patch was only testing it with a QEMU model,
which I presume does not emulate enough for the netdev to be brought
up (author's replies are not visible in lore because they kept sending
their emails in HTML).

The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call.
Complicating things, however, is that POWER8 systems need some per-cpu
state and kmalloc, which isn't available at this stage. So we split
things up into an early phase and a later opportunistic phase. This
commit also removes some noisy log messages that don't add much.

Add support for further HXN (G) type devices (GT variant, GL variant, GS
variant and GR) and document the bcdDevice mapping.
Note that the TA and TB types use the same bcdDevice as some GT and GE
variants, respectively, but that the HX status request can be used to
determine which is which.
Also note that we currently do not distinguish between the various HXN
(G) types in the driver but that this may change eventually (e.g. when
adding GPIO support).

Simon reports that if two LAN9514 USB adapters are directly connected
without an intermediate switch, the link fails to come up and link LEDs
remain dark. The issue was introduced by commit 1ce8b37241ed ("usbnet:
smsc95xx: Forward PHY interrupts to PHY driver to avoid polling").
The PHY suffers from a known erratum wherein link detection becomes
unreliable if Energy Detect Power-Down is used. In poll mode, the
driver works around the erratum by briefly disabling EDPD for 640 msec
to detect a neighbor, then re-enabling it to save power.
In interrupt mode, no interrupt is signaled if EDPD is used by both link
partners, so it must not be enabled at all.
We'll recoup the power savings by enabling SUSPEND1 mode on affected
LAN95xx chips in a forthcoming commit.

We have re-polling for partial IO, so a request can be polled twice. If
it used two poll entries the first time then on the second
io_arm_poll_handler() it will find the old apoll entry and NULL
kmalloc()'ed second entry, i.e. apoll->double_poll, so leaking it.

Do not allow setting less channels, than Traffic Classes there are
via ethtool. There must be at least one channel per Traffic Class.
If you set less channels, than Traffic Classes there are, then during
ice_vsi_rebuild there would be allocated only the requested amount
of tx/rx rings in ice_vsi_alloc_arrays. But later in ice_vsi_setup_q_map
there would be requested at least one channel per Traffic Class. This
results in setting num_rxq > alloc_rxq and num_txq > alloc_txq.
Later, there would be a NULL pointer dereference in
ice_vsi_map_rings_to_vectors, because we go beyond of rx_rings or
tx_rings arrays.
Change ice_set_channels() to return error if you try to allocate less
channels, than Traffic Classes there are.
Change ice_vsi_setup_q_map() and ice_vsi_setup_q_map_mqprio() to return
status code instead of void.
Add error handling for ice_vsi_setup_q_map() and
ice_vsi_setup_q_map_mqprio() in ice_vsi_init() and ice_vsi_cfg_tc().

In current implementation ice_update_phy_type enables all link modes
for selected speed. This approach doesn't work for 1000M speeds,
because both copper (1000baseT) and optical (1000baseX) standards
cannot be enabled at once.
Fix this, by adding the function `ice_set_phy_type_from_speed()`
for 1000M speeds.

Commit 34a897758efe ("ice: Add support for inner etype in switchdev")
added the ability to match on inner ethertype. A side effect of that change
is that it is now impossible to add some filters for protocols which do not
contain inner ethtype field. tc requires the protocol field to be specified
when providing certain other options, e.g. src_ip. This is a problem in
case of GTP - when user wants to specify e.g. src_ip, they also need to
specify protocol in tc command (otherwise tc fails with: Illegal "src_ip").
Because GTP is a tunnel, the protocol field is treated as inner protocol.
GTP does not contain inner ethtype field and the filter cannot be added.
To fix this, ignore the ethertype field in case of GTP filters.

Commit 5291984004edf ("dm: fix bio polling to handle possibile

dm_io_complete() without first queueing the bio to DM if BLK_STS_AGAIN
occurs and bio-polling is _not_ being used.
Fix this by only returning early from dm_io_complete() if the bio has
first been properly queued to DM. Otherwise, the bio will never finish
via bio_endio.

During postsuspend dm-era does the following:
1. Archives the current era
2. Commits the metadata, as part of the RPC call for archiving the
current era
3. Stops the worker
Until the worker stops, it might write to the metadata again. Moreover,
these writes are not flushed to disk immediately, but are cached by the
dm-bufio client, which writes them back asynchronously.
As a result, the committed metadata of a suspended dm-era device might
not be consistent with the in-core metadata.
In some cases, this can result in the corruption of the on-disk
metadata. Suppose the following sequence of events:
1. Load a new table, e.g. a snapshot-origin table, to a device with a
dm-era table
2. Suspend the device
3. dm-era commits its metadata, but the worker does a few more metadata
writes until it stops, as part of digesting an archived writeset
4. These writes are cached by the dm-bufio client
5. Load the dm-era table to another device.
6. The new instance of the dm-era target loads the committed, on-disk
metadata, which don't include the extra writes done by the worker
after the metadata commit.
7. Resume the new device
8. The new dm-era target instance starts using the metadata
9. Resume the original device
10. The destructor of the old dm-era target instance is called and
destroys the dm-bufio client, which results in flushing the cached
writes to disk
11. These writes might overwrite the writes done by the new dm-era
instance, hence corrupting its metadata.
Fix this by committing the metadata after the worker stops running.
stop_worker uses flush_workqueue to flush the current work. However, the
work item may re-queue itself and flush_workqueue doesn't wait for
re-queued works to finish.
This could result in the worker changing the metadata after they have
been committed, or writing to the metadata concurrently with the commit
in the postsuspend thread.
Use drain_workqueue instead, which waits until the work and all
re-queued works finish.

available (probably reasonable as simply disabling signature checking
would prevent you from loading any driver modules).
Deal with this by adding a minimal test.
