Pull ARM DT and driver fixes from Arnd Bergmann:
 "For the devicetree files, there are a total of 20 patches, almost
  entirely for 32-bit machines:

   - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
     both for correctness and for style that are addressed in separate
     patches. This causes most of the changed lines of the DT updates
     this time.

   - More Allwinner updates fixing the identification of the security
     system on sun8i/A33, a recent regression of the A83t ethernet, and
     a few board specific issues on the TBS-A711 macine.

   - Several bug fixes for OMAP dts files, most notably fixing the
     timings for the NAND flash on the Nokia N900 that regressed a while
     ago after the move to configuring them from DT. Some other OMAPs
     now set the correct dma limits on the L3 bus, and a regression fix
     addresses lost Ethernet on dm814x

   - One incorrect setting in the newly added Raspberry Pi Zero W that
     may cause issues with the SD card controller.

   - A missing property on the bcm2835 firmware node caused incorrect
     DMA settings.

   - An old bug on the oxnas platform causing spurious interrupts is
     finally addressed.

   - A regression on the Exynos Midas board broke the OLED panel power
     supply.

   - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
     is now set to the values from the datasheet.

   - Some 64-bit machines use a deprecated string to identify the PSCI
     firmware.

  There are also several small code fixes addressing mostly serious
  issues:

   - Fix the sunxi rsb bus access to no longer return incorrect data
     when mixing 8 and 16 bit I/O.

   - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
     quirk in the ti-sysc driver

   - Fix a NULL pointer access from a race in the fsl dpio driver

   - Fix a v5.5 regression in the exynos-chipid driver that caused an
     invalid error code probing the device on non-exynos platforms

time:

This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one

however that leads to:

When it's probing all of a fileserver's interfaces to find which one is
best to use, afs_do_probe_fileserver() takes a lock on the server record
and notes the pointer to the address list.

It doesn't, however, pin the address list, so as soon as it drops the
lock, there's nothing to stop the address list from being freed under
us.

Fix this by taking a ref on the address list inside the locked section
and dropping it at the end of the function.

The original single target IPI fastpath patch forgot to filter the

this feature since wakeup the multiple sleeping vCPUs will extend
the interrupt disabled time, it especially worse in the over-subscribe
and VM has a little bit more vCPUs scenario. Let's narrow it down to
single target IPI.

Two VMs, each is 76 vCPUs, one running 'ebizzy -M', the other
running cyclictest on all vCPUs, w/ this patch, the avg score
of cyclictest can improve more than 5%. (pv tlb, pv ipi, pv

net/netfilter/nft_fwd_netdev.c: In function ‘nft_fwd_netdev_eval’:
    net/netfilter/nft_fwd_netdev.c:32:10: error: ‘struct sk_buff’ has no member named ‘tc_redirected’
      pkt->skb->tc_redirected = 1;

      pkt->skb->tc_from_ingress = 1;
              ^~

To avoid a direct dependency with tc actions from netfilter, wrap the
redirect bits around CONFIG_NET_REDIRECT and move helpers to
include/linux/skbuff.h. Turn on this toggle from the ifb driver, the
only existing client of these bits in the tree.

This patch adds skb_set_redirected() that sets on the redirected bit
on the skbuff, it specifies if the packet was redirect from ingress
and resets the timestamp (timestamp reset was originally missing in the
netfilter bugfix).

Currently ENA only provides the PCI remove() handler, used during rmmod
for example. This is not called on shutdown/kexec path; we are potentially
creating a failure scenario on kexec:

(a) Kexec is triggered, no shutdown() / remove() handler is called for ENA;
instead pci_device_shutdown() clears the master bit of the PCI device,
stopping all DMA transactions;

(b) Kexec reboot happens and the device gets enabled again, likely having
its FW with that DMA transaction buffered; then it may trigger the (now
invalid) memory operation in the new kernel, corrupting kernel memory area.

This patch aims to prevent this, by implementing a shutdown() handler
quite similar to the remove() one - the difference being the handling
of the netdev, which is unregistered on remove(), but following the
convention observed in other drivers, it's only detached on shutdown().

This prevents an odd issue in AWS Nitro instances, in which after the 2nd
kexec the next one will fail with an initrd corruption, caused by a wild
DMA write to invalid kernel memory. The lspci output for the adapter
present in my instance is:
