Merge tag 'for-linus-5.13b-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross:
- a fix for a boot regression when running as PV guest on hardware
without NX support
- a small series fixing a bug in the Xen pciback driver when
configuring a PCI card with multiple virtual functions
* tag 'for-linus-5.13b-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
xen-pciback: reconfigure also from backend watch handler
xen-pciback: redo VF placement in the virtual topology
x86/Xen: swap NX determination and GDT setup on BSP
While enabling EDAC support for the LS1028A it was discovered that the
memory node has a wrong endianness setting as well as a wrong interrupt
assignment. Fix both.
This was tested on a sl28 board. To force ECC errors, you can use the
error injection supported by the controller in hardware (with
CONFIG_EDAC_DEBUG enabled):
# enable error injection
$ echo 0x100 > /sys/devices/system/edac/mc/mc0/inject_ctrl
# flip lowest bit of the data
$ echo 0x1 > /sys/devices/system/edac/mc/mc0/inject_data_lo

snprintf() should be given the full buffer size, not one less. And it
guarantees nul-termination, so doing it manually afterwards is
pointless.
It's even potentially harmful (though probably not in practice because
CPER_REC_LEN is 256), due to the "return how much would have been
written had the buffer been big enough" semantics. I.e., if the bank
and/or device strings are long enough that the "DIMM location ..."
output gets truncated, writing to msg[n] is a buffer overflow.

If the buffer has slashes up to the end then this will read past the end

On some ASUS and MSI machines, the audio codec is alc1220 and the
Headphone is connected to audio mixer 0xf and DAC 0x5, in theory
the Headphone volume is controlled by DAC 0x5 (Heapdhone Playback
Volume), but somehow it is controlled by DAC 0x2 (Front Playback
Volume), maybe this is a defect on the codec alc1220.
Because of this issue, the PA couldn't switch the headphone and
Lineout correctly, If we apply the quirk CLEVO_P950 to those machines,
the Lineout and Headphone will share the audio mixer 0xc and DAC 0x2,
and generate Headphone+LO mixer, then PA could handle them when
switching between them.

Target de-configuration panics at high CPU load because TPGT and WWPN can
be removed on separate threads.
TPGT removal requests a reset HBA on a separate thread and waits for reset
complete (phase1). Due to high CPU load that HBA reset can be delayed for
some time.
WWPN removal does qlt_stop_phase2(). There it is believed that phase1 has
already completed and thus tgt.tgt_ops is subsequently cleared. However,
tgt.tgt_ops is needed to process incoming traffic and therefore this will
cause one of the following panics:

When TCP is used as transport and a program on the
system connects to RDS port 16385, connection is
accepted but denied per the rules of RDS. However,
RDS connections object is left in the list. Next
loopback connection will select that connection
object as it is at the head of list. The connection
attempt will hang as the connection object is set
to connect over TCP which is not allowed
The issue can be reproduced easily, use rds-ping
to ping a local IP address. After that use any
program like ncat to connect to the same IP
address and port 16385. This will hang so ctrl-c out.
Now try rds-ping, it will hang.
To fix the issue this patch adds checks to disallow
the connection object creation and destroys the
connection object.

In a situation where memory allocation or dma mapping fails, an
invalid address is programmed into the descriptor. This can lead
to memory corruption. If the memory allocation fails, DMA should
reuse the previous skb and mapping and drop the packet. This patch
also increments rx drop counter.

We cannot call bcm_sf2_reg_rgmii_cntrl() for a port that is not RGMII,
yet we do that in bcm_sf2_sw_mac_link_up() irrespective of the port's

This has us use raw_smp_processor_id() in iblock's plug_device callout.
smp_processor_id() is not needed here, because we are running from a per
CPU work item that is also queued to run on a worker thread that is
normally bound to a specific CPU. If the worker thread did end up switching
CPUs then it's handled the same way we handle when the work got moved to a
different CPU's worker thread, where we will just end up sending I/O from
the new CPU.

When updating to latest mainline for some testing on the GARDENA smart
gateway based on the MT7628, I noticed that ethernet does not work any
more. Commit e9229ffd55 ("net: ethernet: mtk_eth_soc: implement
dynamic interrupt moderation") introduced this problem, as it missed the
RX_DIM & TX_DIM configuration for this SoC variant. This patch fixes
this by calling mtk_dim_rx() & mtk_dim_tx() in this case as well.

Reduce device link removal code duplication between the cases when
SRCU is enabled and when it is disabled by moving the only differing
piece of it (which is the removal of the link from the consumer and
supplier lists) into a separate wrapper function (defined differently
for each of the cases in question).
No intentional functional impact.

When device_link_free() drops references to the supplier and
consumer devices of the device link going away and the reference
being dropped turns out to be the last one for any of those
device objects, its ->release callback will be invoked and it
may sleep which goes against the SRCU callback execution
requirements.
To address this issue, make the device link removal code carry out
the device_link_free() actions preceded by SRCU synchronization from
a separate work item (the "long" workqueue is used for that, because
it does not matter when the device link memory is released and it may
take time to get to that point) instead of using SRCU callbacks.
While at it, make the code work analogously when SRCU is not enabled
to reduce the differences between the SRCU and non-SRCU cases.

Deprecation warnings are useful only for the developer, not an end user.
Display warnings only when requested using the python -W option. This
stops the display of warnings like:

an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag).
Implicit conversion to integers using __int__ is deprecated, and
may be removed in a future version of Python.
err = app.exec_()
Since the warning can be fixed only in PySide2, we must wait for it to
be finally fixed there.

This apparently happens because Python can be inconsistent about which
class of the name 'Array' gets imported. Fix by importing explicitly by
name so that only the desired 'Array' gets imported.
