8a1786b7d4 net: dsa: mv88e6xxx: remove ATU age out violation print
Currently, the MV88E6XXX_PORT_ASSOC_VECTOR_INT_AGE_OUT bit (interrupt on
age out) is not enabled by the driver, and as a result, the print for
age out violations is dead code.

Remove it until there is some way for this to be triggered.

5f7d78b2b1 ntb_netdev: Use dev_kfree_skb_any() in interrupt context
TX/RX callback handlers (ntb_netdev_tx_handler(),
ntb_netdev_rx_handler()) can be called in interrupt
context via the DMA framework when the respective
DMA operations have completed. As such, any calls
by these routines to free skb's, should use the
interrupt context safe dev_kfree_skb_any() function.

Previously, these callback handlers would call the
interrupt unsafe version of dev_kfree_skb(). This has
not presented an issue on Intel IOAT DMA engines as
that driver utilizes tasklets rather than a hard
interrupt handler, like the AMD PTDMA DMA driver.
On AMD systems, a kernel WARNING message is
encountered, which is being issued from
skb_release_head_state() due to in_hardirq()
being true.

Besides the user visible WARNING from the kernel,
the other symptom of this bug was that TCP/IP performance
across the ntb_netdev interface was very poor, i.e.
approximately an order of magnitude below what was
expected. With the repair to use dev_kfree_skb_any(),
kernel WARNINGs from skb_release_head_state() ceased
and TCP/IP performance, as measured by iperf, was on
par with expected results, approximately 20 Gb/s on
AMD Milan based server. Note that this performance
is comparable with Intel based servers.

Merge tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
   this_cpu_inc() on strong load-store architectures.

 - Introduce new console_list_lock to synchronize a manipulation of the
   list of registered consoles and their flags.

   This is a first step in removing the big-kernel-lock-like behavior of
   console_lock(). This semaphore still serializes console->write()
   calbacks against:

      - each other. It primary prevents potential races between early
        and proper console drivers using the same device.

      - suspend()/resume() callbacks and init() operations in some
        drivers.

      - various other operations in the tty/vt and framebufer
        susbsystems. It is likely that console_lock() serializes even
        operations that are not directly conflicting with the
        console->write() callbacks here. This is the most complicated
        big-kernel-lock aspect of the console_lock() that will be hard
        to untangle.

 - Introduce new console_srcu lock that is used to safely iterate and
   access the registered console drivers under SRCU read lock.

   This is a prerequisite for introducing atomic console drivers and
   console kthreads. It will reduce the complexity of serialization
   against normal consoles and console_lock(). Also it should remove the
   risk of deadlock during critical situations, like Oops or panic, when
   only atomic consoles are registered.

 - Check whether the console is registered instead of enabled on many
   locations. It was a historical leftover.

 - Cleanly force a preferred console in xenfb code instead of a dirty
   hack.

 - A lot of code and comment clean ups and improvements.

   enumeration code (Giulio Benetti).

 - Change the return type of the ACPI driver remove callback to void and
   update its users accordingly (Dawei Li).

 - Add general support for FFH address space type and implement the low-

 - Fix stale comments in the ACPI tables parsing code and make it print

====================
linux-can-next-for-6.2-20221212

this is a pull request of 39 patches for net-next/master.

The first 2 patches are by me fix a warning and coding style in the
kvaser_usb driver.

Vivek Yadav's patch sorts the includes of the m_can driver.

Biju Das contributes 5 patches for the rcar_canfd driver improve the
support for different IP core variants.

Jean Delvare's patch for the ctucanfd drops the dependency on
COMPILE_TEST.

Vincent Mailhol's patch sorts the includes of the etas_es58x driver.

Haibo Chen's contributes 2 patches that add i.MX93 support to the
flexcan driver.

Lad Prabhakar's patch updates the dt-bindings documentation of the
rcar_canfd driver.

Minghao Chi's patch converts the c_can platform driver to
devm_platform_get_and_ioremap_resource().

In the next 7 patches Vincent Mailhol adds devlink support to the
etas_es58x driver to report firmware, bootloader and hardware version.

Xu Panda's patch converts a strncpy() -> strscpy() in the ucan driver.

Ye Bin's patch removes a useless parameter from the AF_CAN protocol.

The next 2 patches by Vincent Mailhol and remove unneeded or unused
pointers to struct usb_interface in device's priv struct in the ucan
and gs_usb driver.

Vivek Yadav's patch cleans up the usage of the RAM initialization in
the m_can driver.

A patch by me add support for SO_MARK to the AF_CAN protocol.

Geert Uytterhoeven's patch fixes the number of CAN channels in the
rcan_canfd bindings documentation.

In the last 11 patches Markus Schneider-Pargmann optimizes the
register access in the t_can driver and cleans up the tcan glue
driver.

TCAN4X5X_ERROR_STATUS is not a status register that needs clearing

error interrupts. Writing TCAN4X5X_CLEAR_ALL_INT to this register
effectively masks everything.

Rename the register and mask all error interrupts only once by writing

005c54278b can: ctucanfd: Drop obsolete dependency on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

There are cables that exist that can support speeds in excess of 10GbE.
The driver, however, restricts the EEPROM advertised nominal bitrate to
a specific range, which can prevent usage of cables that can support,

Rather than checking that an active or passive cable supports a specific
range, only check for a minimum supported speed.

f07fadcbee net: ethernet: dnet: don't call dev_kfree_skb() under spin_lock_irqsave()
It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled.

In this case, the lock is used to protected 'bp', so we can move
dev_kfree_skb() after the spin_unlock_irqrestore().

d1678bf45f net: emaclite: don't call dev_kfree_skb() under spin_lock_irqsave()
It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled.

It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead.
The difference between them is free reason, dev_kfree_skb_irq() means
the SKB is dropped in error and dev_consume_skb_irq() means the SKB
is consumed in normal.

In this case, dev_kfree_skb() is called in xemaclite_tx_timeout() to
drop the SKB, when tx timeout, so replace it with dev_kfree_skb_irq().

The root cause is traced to the netdev and fst_card_info are not freed
when removes one fst in fst_remove_one(), which may trigger oom if
repeated insmod and rmmod module.

Fix it by adding free_netdev() and kfree() in fst_remove_one(), just as
the operations on the error handling path in fst_add_one().

ea6ff77922 can: rcar_canfd: Add multi_channel_irqs to struct rcar_canfd_hw_info
RZ/G2L has separate IRQ lines for tx and error interrupt for each
channel whereas R-Car has a combined IRQ line for all the channel
specific tx and error interrupts.

Add multi_channel_irqs to struct rcar_canfd_hw_info to select the
driver to choose between combined and separate irq registration for
channel interrupts. This patch also removes enum rcanfd_chip_id and
chip_id from both struct rcar_canfd_hw_info, as it is unused.
