In some case, we may use multiple pedit actions to modify packets.
The command shown as below: the last pedit action is effective.
$ tc filter add dev netdev_rep parent ffff: protocol ip prio 1 \
flower skip_sw ip_proto icmp dst_ip 3.3.3.3 \
action pedit ex munge ip dst set 192.168.1.100 pipe \
action pedit ex munge eth src set 00:00:00:00:00:01 pipe \
action pedit ex munge eth dst set 00:00:00:00:00:02 pipe \
action csum ip pipe \
action tunnel_key set src_ip 1.1.1.100 dst_ip 1.1.1.200 dst_port 4789 id 100 \
action mirred egress redirect dev vxlan0
To fix it, we add max_mod_hdr_actions to mlx5e_tc_flow_parse_attr struction,
max_mod_hdr_actions will store the max pedit action number we support and
num_mod_hdr_actions indicates how many pedit action we used, and store all
pedit action to mod_hdr_actions.

When we offload tc filters to hardware, hardware flows can
be updated when mac of encap destination ip is changed.
But we ignore one case, that the mac of local encap ip can
be changed too, so we should also update them.
To fix it, add route_dev in mlx5e_encap_entry struct to save
the local encap netdevice, and when mac changed, kernel will
flush all the neighbour on the netdevice and send NETEVENT_NEIGH_UPDATE
event. The mlx5 driver will delete the flows and add them when neighbour
available again.

Under heavy traffic load, when changing number of channels via
ethtool (ethtool -L) which will cause interface to be reloaded,
it was observed that some packets gets transmitted on old TX
channel/queue id which doesn't really exist after the channel
configuration leads to system crash.
Add a safeguard in the driver by validating queue id through
ndo_select_queue() which is called before the ndo_start_xmit().

git://people.freedesktop.org/~thomash/linux into drm-fixes
A patch set from Christoph for vmwgfx dma mode detection breakage with the
new dma code restructuring in 5.0
A couple of fixes also CC'd stable
Finally an improved IOMMU detection that automatically enables dma mapping
also with other vIOMMUS than the intel one if present and enabled.
Currently trying to start a VM in that case would fail catastrophically.

There are at least four different parts with the same Vendor and Device
ID ([16c3:abcd]):
1) Synopsys HAPS USB3 controller
2) Synopsys PCIe Root Port in Freescale/NXP i.MX6Q (reported by Lucas)
3) Synopsys PCIe Root Port in Freescale/NXP i.MX6QP (reported by Lukas)
4) Synopsys PCIe Root Port in Freescale/NXP i.MX7D (reported by Trent)
The HAPS USB3 controller has a Class Code of PCI_CLASS_SERIAL_USB_XHCI,
which means the XHCI driver would normally claim it. Previously,
quirk_synopsys_haps() changed the Class Code of all [16c3:abcd] devices,
including the Root Ports, to PCI_CLASS_SERIAL_USB_DEVICE to prevent the
XHCI driver from claiming them so dwc3-haps can claim them instead.
Changing the Class Code of the Root Ports prevents the PCI core from
handling them as bridges, so devices below them don't work.
Restrict the quirk so it only changes the Class Code for devices that start
with the PCI_CLASS_SERIAL_USB_XHCI Class Code, leaving the Root Ports
alone.

bio_trim() has an early return, which makes it _not_ idempotent, if the
offset is 0 and the bio's bi_size already matches the requested size.
Prior to DM, all users of bio_trim() were fine with this. But DM has
exposed the fact that bio_trim()'s early return is incompatible with a
cloned bio whose integrity payload must be trimmed via
bio_integrity_trim().
Fix this by reverting DM back to doing the equivalent of bio_trim() but
in an idempotent manner (so bio_integrity_trim is always performed).
Follow-on work is needed to assess what benefit bio_trim()'s early
return is providing to its existing callers.

Block core changes to switch bio-based IO accounting to be percpu had a
side-effect of altering DM core to now rely on calling waitqueue_active
(in both bio-based and request-based) to check if another task is in
dm_wait_for_completion().
A memory barrier is needed before calling waitqueue_active(). DM core
doesn't piggyback on a preceding memory barrier so it must explicitly
use its own.
For more details on why using waitqueue_active() without a preceding
barrier is unsafe, please see the comment before the waitqueue_active()
definition in include/linux/wait.h.
Add the missing memory barrier by switching to using wq_has_sleeper().

Two and a half years ago, the client was changed to use gathered
Send for larger inline messages, in commit 655fec6987b ("xprtrdma:
Use gathered Send for large inline messages"). Several fixes were
required because there are a few in-kernel device drivers whose
max_sge is 3, and these were broken by the change.
Apparently my memory is going, because some time later, I submitted
commit 25fd86eca11c ("svcrdma: Don't overrun the SGE array in
svc_rdma_send_ctxt"), and after that, commit f3c1fd0ee294 ("svcrdma:
Reduce max_send_sges"). These too incorrectly assumed in-kernel
device drivers would have more than a few Send SGEs available.
The fix for the server side is not the same. This is because the
fundamental problem on the server is that, whether or not the client
has provisioned a chunk for the RPC reply, the server must squeeze
even the most complex RPC replies into a single RDMA Send. Failing
in the send path because of Send SGE exhaustion should never be an
option.
Therefore, instead of failing when the send path runs out of SGEs,
switch to using a bounce buffer mechanism to handle RPC replies that
are too complex for the device to send directly. That allows us to
remove the max_sge check to enable drivers with small max_sge to
work again.

printk() for 100+ times per a second. But there is no need to print same

We've received a bugreport that using LPM with a SAMSUNG

a quirk for the MZ7TD256HAFV-000L9, which is also a Samsun EVO 840 /
PM851 OEM model, so it seems some of these models have a LPM issue.
This commits adds a NOLPM quirk for the model string from the new

RDMSR in the trampoline code overwrites EDX but that register is used
to indicate whether 5-level paging has to be enabled and if clobbered,
leads to failure to boot on a 5-level paging machine.
Preserve EDX on the stack while we are dealing with EFER.

commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set
under non-atomic") added new rsnd_ssi_prepare() and moved
rsnd_ssi_master_clk_start() to .prepare.
But, ssi user count (= ssi->usrcnt) is incremented at .init
(= rsnd_ssi_init()).
Because of these timing exchange, ssi->usrcnt check at
rsnd_ssi_master_clk_start() should be adjusted.
Otherwise, 2nd master clock setup will be no check.
This patch fixup this issue.

To detect potential errors, let's add:
a) build-time warnings when the table size isn't aligned with the enum
list
b) run-time warnings when the values are not initialized. This
requires an increase by one of all values to avoid the default 0.

KASAN reports and additional traces point to out-of-bounds accesses to
the dapm_up_seq and dapm_down_seq lookup tables. The indices used are
larger than the array definition.
Fix by adding missing entries for the new widget types in these two
lookup tables, and align them with PGA values.
Also the sequences for the following widgets were not defined. Since
their values defaulted to zero, assign them explicitly
snd_soc_dapm_input
snd_soc_dapm_output
snd_soc_dapm_vmid
snd_soc_dapm_siggen
snd_soc_dapm_sink

Again no functional changes, but only code clean up.
Use a standard macro for initializing the procfs entries, also drop
the info entries stored in dsp_spos_instance, as they are removed
recursively by a single snd_info_free_entry() calls.
