Ido Schimmel 2f25844c23 mlxsw: spectrum: Mark port as active before registering it
Commit bbf2a4757b ("mlxsw: spectrum: Initialize ports at the end of
init sequence") moved ports initialization to the end of the init
sequence, which means ports are the first to be removed during fini.

Since the FDB delayed work is still active when ports are removed it's
possible for it to process FDB notifications of inactive ports,
resulting in a warning message.

Fix that by marking ports as inactive only after unregistering them. The
NETDEV_UNREGISTER event will invoke bridge's driver port removal
sequence that will cause the FDB (and FDB notifications) to be flushed.

Ido Schimmel 05978481e7 mlxsw: spectrum: Create PVID vPort before registering netdevice
After registering a netdevice it's possible for user space applications
to configure an IP address on it. From the driver's perspective, this
means a router interface (RIF) should be created for the PVID vPort.

Therefore, we must create the PVID vPort before registering the
netdevice.

Ido Schimmel fa66d7e3fe mlxsw: spectrum: Remove redundant errors from the code
Currently, when device configuration fails we emit errors to the kernel
log despite the fact we already get these from the EMAD transaction
layer, so remove them.

In addition to being unnecessary, removing these error messages will
allow us to reuse mlxsw_sp_port_add_vid() to create the PVID vPort
before registering the netdevice.

Ido Schimmel 7a35583ec5 mlxsw: spectrum: Don't return upon error in removal path
When removing a VLAN filter from the device we shouldn't return upon the
first error we encounter, as otherwise we'll have resources that will
never be freed nor used.

Instead, we should keep trying to free as much resources as possible in
a best effort mode.

Remove the error message as well, since we already get these from the
EMAD transaction code.

Ard Biesheuvel bc9f3d7788 arm64: kernel: avoid literal load of virtual address with MMU off
Literal loads of virtual addresses are subject to runtime relocation when
CONFIG_RELOCATABLE=y, and given that the relocation routines run with the
MMU and caches enabled, literal loads of relocated values performed with
the MMU off are not guaranteed to return the latest value unless the
memory covering the literal is cleaned to the PoC explicitly.

So defer the literal load until after the MMU has been enabled, just like
we do for primary_switch() and secondary_switch() in head.S.

Heinz Mauelshagen 9e7d9367e6 dm raid: support raid0 with missing metadata devices
The raid0 MD personality does not start a raid0 array with any of its
data devices missing.

dm-raid was removing data/metadata device pairs unconditionally if it
failed to read a superblock off the respective metadata device of such
pair, resulting in failure to start arrays with the raid0 personality.

Avoid removing any data/metadata device pairs in case of raid0
(e.g. lvm2 segment type 'raid0_meta') thus allowing MD to start the
array.

Also, avoid region size validation for raid0.

simply overlooked.

Arnd Bergmann 16c8eba0fe clocksource/drivers/kona: Fix get_counter() error handling
I could not figure out why, but GCC cannot prove that the
kona_timer_init() function always initializes its two outputs,
and we get a warning for the use of the 'lsw' variable later,
which is obviously correct.

  drivers/clocksource/bcm_kona_timer.c: In function 'kona_timer_init':
  drivers/clocksource/bcm_kona_timer.c:119:13: error: 'lsw' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Slightly reordering the loop makes the warning disappear, after
it becomes more obvious to the compiler that the loop is
always entered on the first iteration.

As pointed out by Ray Jui, there is a related problem in the
way we deal with the loop running into the limit, as we just
keep going there with an invalid counter data, so instead we
now propagate a -ETIMEDOUT result to the caller.

wants to set up.  This bug was discovered by running generic/299

When we do DAX IO, we try to invalidate the entire page cache held

tree that now tracks dirty state in exceptional entries in the radix

What we are trying to do is remove cached pages (e.g from reads
into holes) that sit in the radix tree over the range we are about
to write to. Hence we should just limit the invalidation to the
range we are about to overwrite.

file systems, and has increased in severity with the new buffered
write path.

Brian Foster 4dd3fd7197 xfs: don't assert fail on non-async buffers on ioacct decrement
The buffer I/O accounting mechanism tracks async buffers under I/O.  As
an optimization, the buffer I/O count is incremented only once on the
first async I/O for a given hold cycle of a buffer and decremented once
the buffer is released to the LRU (or freed).

xfs_buf_ioacct_dec() has an ASSERT() check for an XBF_ASYNC buffer, but
we have one or two corner cases where a buffer can be submitted for I/O
multiple times via different methods in a single hold cycle. If an async
I/O occurs first, the I/O count is incremented. If a sync I/O occurs
before the hold count drops, XBF_ASYNC is cleared by the time the I/O
count is decremented.

Remove the async assert check from xfs_buf_ioacct_dec() as this is a
perfectly valid scenario. For the purposes of I/O accounting, we really
only care about the buffer async state at I/O submission time.

Dave Ertman fbfe12c64f i40e: check for and deal with non-contiguous TCs
The i40e driver was causing a kernel panic when
non-contiguous Traffic Classes, or Traffic Classes not
starting with TC0, were configured on a link partner switch.
i40e does not support non-contiguous TCs.

To fix this, the patch changes the logic when determining
the total number of TCs enabled.  Before, this would use the
highest TC number enabled and assume that all TCs below it were
also enabled.  Now, we create a bitmask of enabled TCs and scan
it to determine not only the number of TCs, but also if the set

Heinz Mauelshagen a3c06a3897 dm raid: enhance attempt_restore_of_faulty_devices() to support more devices
attempt_restore_of_faulty_devices() is limited to 64 when it should support
the new maximum of 253 when identifying any failed devices. It clears any
revivable devices via an MD personality hot remove and add cylce to allow
for their recovery.

Address by using existing functions to retrieve and update all failed
devices' bitfield members in the dm raid superblocks on all RAID devices
and check for any devices to clear in it.

Whilst on it, don't call attempt_restore_of_faulty_devices() for any MD
personality not providing disk hot add/remove methods (i.e. raid0 now),
because such personalities don't support reviving of failed disks.

Alexander Duyck 3d951822be ixgbe: Re-enable ability to toggle VLAN filtering
Back when I submitted the GSO code I messed up and dropped the support for
disabling the VLAN tag filtering via the feature bit.  This patch
re-enables the use of the NETIF_F_HW_VLAN_CTAG_FILTER to enable/disable the
VLAN filtering independent of toggling promiscuous mode.

Heinz Mauelshagen 31e10a4120 dm raid: fix restoring of failed devices regression
'lvchange --refresh RaidLV' causes a mapped device suspend/resume cycle
aiming at device restore and resync after transient device failures.  This
failed because flag RT_FLAG_RS_RESUMED was always cleared in the suspend path,
thus the device restore wasn't performed in the resume path.

Solve by removing RT_FLAG_RS_RESUMED from the suspend path and resume
unconditionally.  Also, remove superfluous comment from raid_resume().

Alexander Duyck f60439bc21 ixgbe: Force VLNCTRL.VFE to be set in all VMDq paths
When I was adding the code for enabling VLAN promiscuous mode with SR-IOV
enabled I had inadvertently left the VLNCTRL.VFE bit unchanged as I has
assumed there was code in another path that was setting it when we enabled
SR-IOV.  This wasn't the case and as a result we were just disabling VLAN
filtering for all the VFs apparently.

Also the previous patches were always clearing CFIEN which was always set
to 0 by the hardware anyway so I am dropping the redundant bit clearing.

Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of
certain interrupt types, pass positive flags like PCI_IRQ_LEGACY,
PCI_IRQ_MSI, etc., to specify the acceptable interrupt types.

This is based on a number of pending driver conversions that just happend
to be a whole more obvious to read this way, and given that we have no
users in the tree yet it can still easily be done.

I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting

This is prepatory work for an expanding list of adapter families that have
occasional ~10 hour clock jumps when being used for PTP. Factor out the
sanitization function and convert to using a feature (bug) flag, per
suggestion from Jesse Brandeburg.

Littering functional code with device-specific checks is much messier than
simply checking a flag, and having device-specific init set flags as needed.
There are probably a number of other cases in the e1000e code that
could/should be converted similarly.

Kshitiz Gupta 0066c8b6f4 igb: fix adjusting PTP timestamps for Tx/Rx latency
Fix PHY delay compensation math in igb_ptp_tx_hwtstamp() and
igb_ptp_rx_rgtstamp. Add PHY delay compensation in
igb_ptp_rx_pktstamp().

In the IGB driver, there are two functions that retrieve timestamps
received by the PHY - igb_ptp_rx_rgtstamp() and igb_ptp_rx_pktstamp().
The previous commit only changed igb_ptp_rx_rgtstamp(), and the change
was incorrect.

There are two instances in which PHY delay compensations should be
made:

- Before the packet transmission over the PHY, the latency between
  when the packet is timestamped and transmission of the packets,
  should be an add operation, but it is currently a subtract.

- After the packets are received from the PHY, the latency between
  the receiving and timestamping of the packets should be a subtract
  operation, but it is currently an add.

James Morse 924d869675 PM / hibernate: Fix rtree_next_node() to avoid walking off list ends
rtree_next_node() walks the linked list of leaf nodes to find the next
block of pages in the struct memory_bitmap. If it walks off the end of
the list of nodes, it walks the list of memory zones to find the next
region of memory. If it walks off the end of the list of zones, it
returns false.

This leaves the struct bm_position's node and zone pointers pointing
at their respective struct list_heads in struct mem_zone_bm_rtree.

memory_bm_find_bit() uses struct bm_position's node and zone pointers
to avoid walking lists and trees if the next bit appears in the same
node/zone. It handles these values being stale.

Swap rtree_next_node()s 'step then test' to 'test-next then step',
this means if we reach the end of memory we return false and leave
the node and zone pointers as they were.

This fixes a panic on resume using AMD Seattle with 64K pages:

Here struct mem_zone_bm_rtree's start_pfn has been returned instead of

This behaviour was exposed by commit 6dbecfd345 ("PM / hibernate:

Mathias Nyman 33be126510 xhci: always handle "Command Ring Stopped" events
Fix "Command completion event does not match command" errors by always
handling the command ring stopped events.

The command ring stopped event is generated as a result of aborting
or stopping the command ring with a register write. It is not caused
by a command in the command queue, and thus won't have a matching command
in the comman list.

Solve it by handling the command ring stopped event before checking for a
matching command.

In most command time out cases we abort the command ring, and get
a command ring stopped event. The events command pointer will point at
the current command ring dequeue, which in most cases matches the timed
out command in the command list, and no error messages are seen.

If we instead get a command aborted event before the command ring stopped
event, the abort event will increse the command ring dequeue pointer, and
the following command ring stopped events command pointer will point at the
next, not yet queued command. This case triggered the error message

sean.wang@mediatek.com 55a4e77819 net: ethernet: mediatek: fix runtime warning raised by inconsistent struct device pointers passed to DMA API
Runtime warning occurs if DMA-API debug feature is enabled that would be
raised by pointers passed to DMA API as arguments to inconsistent struct
device objects, so that the patch makes them usage aligned between DMA
operations such as dma_map_*() and dma_unmap_*() to eliminate the warning.

sean.wang@mediatek.com b2025c7cc9 net: ethernet: mediatek: fix flow control settings on GMAC0 is not being enabled properly
Commit 08ef55c6f2
("net-next: mediatek: fix gigabit and flow control advertisement")
had supported proper flow control settings for GMAC1. But for GMAC0,

1.GMAC0 shares the common logic with GMAC1 inside mtk_phy_link_adjust()
to adapt various settings for the target phy.

2.GMAC0 uses fixed-phy to connect to a builtin gigabit switch with
fixed link speed as commit 0c72c50f6f
("net-next: mediatek: add fixed-phy support") describes.

3.However, fixed-phy doesn't enable SUPPORTED_Pause & SUPPORTED_Asym_Pause
supported flag on default that would cause mtk_phy_link_adjust() not to
enable flow control setting on GMAC0 properly and cause packet dropped
when high traffic.

Due to these reasons, the patch adds SUPPORTED_Pause & SUPPORTED_Asym_Pause
supported flags on fixed-phy used by the driver to have proper handling on
the both GMAC with the shared common logic.
