Pull ARM SoC fixes from Arnd Bergmann:
"Another smaller set of fixes for three of the Arm platforms:
TI OMAP:
Fix swapped mmc device order also for omap3 that got changed with
the recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the
aliases should be board specific, all the mmc device instances are
all there in the SoC, and we do probe them by default so that PM
runtime can idle the devices if left enabled from the bootloader.
Qualcomm Snapdragon:
This bypasses the recently introduced interconnect handling in
the GENI (serial engine) driver when running off ACPI, as this
causes the GENI probe to fail and the Lenovo Yoga C630 to boot
without keyboard and touchpad.
Allwinner:
One 32kHz clock fix for the beelink gs1, a CD polarity fix for the
SoPine, some MAINTAINERS maintainance, and a clk / reset switch to

vmwgfx fixes for regressions in 5.12
Here's a set of 3 patches fixing ugly regressions
in the vmwgfx driver. We broke lock initialization
code and ended up using spinlocks before initialization
breaking lockdep.
Also there was a bit of a fallout from drm changes
which made the core validate that unreferenced buffers
have been unpinned. vmwgfx pinning code predates a lot
of the core drm and wasn't written to account for those
semantics. Fortunately changes required to fix it
are not too intrusive.
The changes have been validated by our internal ci.

Pull CXL memory class fixes from Dan Williams:
"A collection of fixes for the CXL memory class driver introduced in
this release cycle.
The driver was primarily developed on a work-in-progress QEMU
emulation of the interface and we have since found a couple places
where it hid spec compliance bugs in the driver, or had a spec
implementation bug itself.
The biggest change here is replacing a percpu_ref with an rwsem to
cleanup a couple bugs in the error unwind path during ioctl device
init. Lastly there were some minor cleanups to not export the
power-management sysfs-ABI for the ioctl device, use the proper sysfs
helper for emitting values, and prevent subtle bugs as new
administration commands are added to the supported list.
The bulk of it has appeared in -next save for the top commit which was
found today and validated on a fixed-up QEMU model.
Summary:
- Fix support for CXL memory devices with registers offset from the
BAR base.
- Fix the reporting of device capacity.
- Fix the driver commands list definition to be disconnected from the
UAPI command list.
- Replace percpu_ref with rwsem to fix initialization error path.
- Fix leaks in the driver initialization error path.
- Drop the power/ directory from CXL device sysfs.
- Use the recommended sysfs helper for attribute 'show'
implementations"
* tag 'cxl-fixes-for-5.12-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl:

cxl/mem: Fix register block offset calculation
cxl/mem: Force array size of mem_commands[] to CXL_MEM_COMMAND_ID_MAX

cxl/mem: Fix synchronization mechanism for device removal vs ioctl operations
cxl/mem: Use sysfs_emit() for attribute show routines
|

The CXL Identify Memory Device output payload emits capacity in 256MB
units. The driver is treating the capacity field as bytes. This was
missed because QEMU reports bytes when it should report bytes / 256MB.

The "Register Offset Low" register of a "DVSEC Register Locator"
contains the 64K aligned offset for the registers along with the BAR
indicator and an id. The implementation was treating the "Register Block
Offset Low" field a value rather than as a pre-aligned component of the
64-bit offset. So, just mask, don't mask and shift (FIELD_GET).
The user visible result of this bug is that the driver fails to bind to
the device after none of the required blocks are found.
This was missed earlier because the primary development done in the QEMU
environment only uses 0 offsets, i.e. 0 shifted is still 0.

Fix this panic by adding more rules to calculate the value of @rss_size_max
which could be used in allocating the queues when bpf is loaded, which,
however, could cause the failure and then trigger the NULL pointer of
vsi->rx_rings. Prio to this fix, the machine doesn't care about how many
cpus are online and then allocates 256 queues on the machine with 32 cpus
online actually.
Once the load of bpf begins, the log will go like this "failed to get
tracking for 256 queues for VSI 0 err -12" and this "setup of MAIN VSI
failed".
Thus, I attach the key information of the crash-log here.

I noticed a weird bug with this driver on Marvell CN9130 Customer
Reference Board.
Sometime after boot, the system locks with the following message:
[104.071363] i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
The system does not respond afterwards, only warns about RCU stalls.
This first appeared with commit e5c02cf54154 ("i2c: mv64xxx: Add runtime
PM support").
With further experimentation I discovered that adding a delay into
mv64xxx_i2c_hw_init() fixes this issue. This function is called before
every xfer, due to how runtime PM works in this driver. It seems that in
order to work correctly, a delay is needed after the bus is reset in
this function.
Since there already is a known erratum with this controller needing a
delay, I assume that this is just another place this needs to be
applied. Therefore I apply the delay only if errata_delay is true.

This reverts commit 9c63faaa931e443e7abbbee9de0169f1d4710546, which
introduces a suspend/resume regression on Jetson TX2 boards that can be
reproduced every time. Given that the issue that this was supposed to
fix only occurs very sporadically the safest course of action is to
revert before v5.12 and then we can have another go at fixing the more
rare issue in the next release (and perhaps backport it if necessary).
The root cause of the observed problem seems to be that when the system
is suspended, some packets are still in transit. When the descriptors
for these buffers are cleared on resume, the descriptors become invalid
and cause a fatal bus error.

resulting in every subsequent cotable resize trying to release a

the pin.

We were not correctly unpinning no longer needed buffers. In particular
vmw_buffer_object, which is internally often pinned on creation wasn't
unpinned on destruction and none of the internal MOB buffers were
unpinned before being put back. Technically this existed for a
long time but commit 57fcd550eb15 ("drm/ttm: Warn on pinning without
holding a reference") introduced a WARN_ON which was filling up the
kernel logs rather quickly.
Quite frankly internal usage of vmw_buffer_object and in general
pinning needs to be refactored in vmwgfx but for now this makes
it work.

Remove the unnecessary napi_schedule() call in __ibmvnic_open() since
interrupt_rx() calls napi_schedule_prep/__napi_schedule during every

During adapter reset, do_reset/do_hard_reset calls ibmvnic_open(),
which will calls napi_schedule if previous state is VNIC_CLOSED
(i.e, the reset case, and "ifconfig down" case). So there is no need
for do_reset to call napi_schedule again at the end of the function
though napi_schedule will neglect the request if napi is already
scheduled.

__ibmvnic_open calls napi_disable without checking whether NAPI polling
has already been disabled or not. This could cause napi_disable
being called twice, which could generate deadlock. For example,
the first napi_disable will spin until NAPI_STATE_SCHED is cleared
by napi_complete_done, then set it again.
When napi_disable is called the second time, it will loop infinitely
because no dev->poll will be running to clear NAPI_STATE_SCHED.
To prevent above scenario from happening, call ibmvnic_napi_disable()
which checks if napi is disabled or not before calling napi_disable.

It has been reported [0] that using pause frames in jumbo mode impacts
performance. There's no available chip documentation, but vendor
drivers r8168 and r8125 don't advertise pause in jumbo mode. So let's
do the same, according to Roman it fixes the issue.

commit df7b59ba9245 ("dm verity: fix FEC for RS roots unaligned to
block size") introduced the possibility for misaligned roots IO
relative to the underlying device's logical block size. E.g. Android's
default RS roots=2 results in dm_bufio->block_size=1024, which causes
the following EIO if the logical block size of the device is 4096,
given v->data_dev_block_bits=12:
E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size
E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0
E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5
Fix this by onlu using f->roots for dm_bufio blocksize IFF it is
aligned to v->data_dev_block_bits.

The logic in connect() is currently written with the assumption that
xenbus_watch_pathfmt() will return an error for a node that does not
exist. This assumption is incorrect: xenstore does allow a watch to
be registered for a nonexistent node (and will send notifications
should the node be subsequently created).
As of commit 1f2565780 ("xen-netback: remove 'hotplug-status' once it
has served its purpose"), this leads to a failure when a domU
transitions into XenbusStateConnected more than once. On the first
domU transition into Connected state, the "hotplug-status" node will
be deleted by the hotplug_status_changed() callback in dom0. On the
second or subsequent domU transition into Connected state, the
hotplug_status_changed() callback will therefore never be invoked, and
so the backend will remain stuck in InitWait.
This failure prevents scenarios such as reloading the xen-netfront
module within a domU, or booting a domU via iPXE. There is
unfortunately no way for the domU to work around this dom0 bug.
Fix by explicitly checking for existence of the "hotplug-status" node,
thereby creating the behaviour that was previously assumed to exist.

A for-loop is using a u8 loop counter that is being compared to
a u32 cmp_dcbcfg->numapp to check for the end of the loop. If
cmp_dcbcfg->numapp is larger than 255 then the counter j will wrap
around to zero and hence an infinite loop occurs. Fix this by making
counter j the same type as cmp_dcbcfg->numapp.

pci_disable_device() called in __ixgbe_shutdown() decreases
dev->enable_cnt by 1. pci_enable_device_mem() which increases
dev->enable_cnt by 1, was removed from ixgbe_resume() in commit
6f82b2558735 ("ixgbe: use generic power management"). This caused
unbalanced increase/decrease. So add pci_enable_device_mem() back.

The ixgbe driver currently generates a NULL pointer dereference when
performing the ethtool loopback test. This is due to the fact that there
isn't a q_vector associated with the test ring when it is setup as
interrupts are not normally added to the test rings.
To address this I have added code that will check for a q_vector before
returning a napi_id value. If a q_vector is not present it will return a
value of 0.

Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature
sensor reading"), Linux reports the temperature of Topaz hwmon as
constant -75°C.
This is because switches from the Topaz family (88E6141 / 88E6341) have
the address of the temperature sensor register different from Peridot.
This address is instead compatible with 88E1510 PHYs, as was used for
Topaz before the above mentioned commit.
Create a new mapping table between switch family and PHY ID for families
which don't have a model number. And define PHY IDs for Topaz and Peridot
families.
Create a new PHY ID and a new PHY driver for Topaz's internal PHY.
The only difference from Peridot's PHY driver is the HWMON probing
method.
Prior this change Topaz's internal PHY is detected by kernel as:
PHY [...] driver [Marvell 88E6390] (irq=63)
And afterwards as:
PHY [...] driver [Marvell 88E6341 Family] (irq=63)
