"I've collected a handful of fixes over the past few weeks:
- A fix to un-break the build-id argument to the vDSO build, which is
necessary for the LLVM linker.
- A fix to initialize the jump label subsystem, without which it (and

- A fix to include <asm/barrier.h> from <vdso/processor.h>, without
which some drivers won't compile"

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING
Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW
ACTIVE_HIGH => IRQ_TYPE_LEVEL_HIGH

send_login() does not check for the result of ibmvnic_send_crq() of the
login request. This results in the driver needlessly retrying the login
10 times even when CRQ is no longer active. Check the return code and
give up in case of errors in sending the CRQ.
The only time we want to retry is if we get a PARITALSUCCESS response
from the partner.

the worker thread will start reset process and free the login response

When inet_rtm_getroute() was converted to use the RCU variants of
ip_route_input() and ip_route_output_key(), the TOS parameters
stopped being masked with IPTOS_RT_MASK before doing the route lookup.
As a result, "ip route get" can return a different route than what
would be used when sending real packets.
For example:
$ ip route add 192.0.2.11/32 dev eth0
$ ip route add unreachable 192.0.2.11/32 tos 2
$ ip route get 192.0.2.11 tos 2
RTNETLINK answers: No route to host
But, packets with TOS 2 (ECT(0) if interpreted as an ECN bit) would
actually be routed using the first route:
$ ping -c 1 -Q 2 192.0.2.11
PING 192.0.2.11 (192.0.2.11) 56(84) bytes of data.
64 bytes from 192.0.2.11: icmp_seq=1 ttl=64 time=0.173 ms
--- 192.0.2.11 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.173/0.173/0.173/0.000 ms
This patch re-applies IPTOS_RT_MASK in inet_rtm_getroute(), to
return results consistent with real route lookups.

Netfilter changes PACKET_OTHERHOST to PACKET_HOST before invoking the
hooks as, while it's an expected value for a bridge, routing expects
PACKET_HOST. The change is undone later on after hook traversal. This
can be seen with pairs of functions updating skb>pkt_type and then
reverting it to its original value:
For hook NF_INET_PRE_ROUTING:
setup_pre_routing / br_nf_pre_routing_finish
For hook NF_INET_FORWARD:
br_nf_forward_ip / br_nf_forward_finish
But the third case where netfilter does this, for hook
NF_INET_POST_ROUTING, the packet type is changed in br_nf_post_routing
but never reverted. A comment says:
/* We assume any code from br_dev_queue_push_xmit onwards doesn't care
* about the value of skb->pkt_type. */
But when having a tunnel (say vxlan) attached to a bridge we have the
following call trace:
br_nf_pre_routing
br_nf_pre_routing_ipv6
br_nf_pre_routing_finish
br_nf_forward_ip
br_nf_forward_finish
br_nf_post_routing <- pkt_type is updated to PACKET_HOST
br_nf_dev_queue_xmit <- but not reverted to its original value
vxlan_xmit
vxlan_xmit_one
skb_tunnel_check_pmtu <- a check on pkt_type is performed
In this specific case, this creates issues such as when an ICMPv6 PTB
should be sent back. When CONFIG_BRIDGE_NETFILTER is enabled, the PTB
isn't sent (as skb_tunnel_check_pmtu checks if pkt_type is PACKET_HOST
and returns early).
If the comment is right and no one cares about the value of
skb->pkt_type after br_dev_queue_push_xmit (which isn't true), resetting
it to its original value should be safe.

ASUS Zephyrus G14 has two speaker pins, and the auto-parser tries to
assign an individual DAC to each pin as much as possible.
Unfortunately the third DAC has no volume control unlike the two DACs,
and this resulted in the inconsistent speaker volumes.
As a workaround, wire both speaker pins to the same DAC by modifying
the existing quirk (ALC289_FIXUP_ASUS_GA401) applied to this device.
Since this quirk entry is chained by another, we need to avoid
applying the DAC assignment change for it. Luckily, there is another
quirk entry (ALC289_FIXUP_ASUS_GA502) doing the very same thing, so we
can chain to the GA502 quirk instead.
Note that this patch uses a new flag of the generic parser,
obey_preferred_dacs, for enforcing the DACs.

The generic parser accepts the preferred_dacs[] pairs as a hint for
assigning a DAC to each pin, but this hint doesn't work always
effectively. Currently it's merely a secondary choice after the trial
with the path index failed. This made sometimes it difficult to
assign DACs without mimicking the connection list and/or the badness
table.
This patch adds a new flag, obey_preferred_dacs, that changes the
behavior of the parser. As its name stands, the parser obeys the
given preferred_dacs[] pairs by skipping the path index matching and
giving a high penalty if no DAC is assigned by the pairs. This mode
will help for assigning the fixed DACs forcibly from the codec
driver.

This patch fixes the hierarchical structure of MHI devices. Indeed,
MHI client devices are directly 'enumerated' from the mhi controller
and therefore must be direct descendants/children of their mhi
controller device, in accordance with the Linux Device Model.
Today both MHI clients and controller devices are at the same level,
this patch ensures that MHI controller is parent of its client devices.
The hierarchy is especially important for power management (safe
suspend/resume order). It is also useful for userspace to determine
relationship between MHI client devices and controllers.

Today the MHI controller name is simply cloned from the underlying
bus device (its parent), that gives the following device structure
for e.g. a MHI/PCI controller:
devices/pci0000:00/0000:00:01.2/0000:02:00.0/0000:02:00.0
devices/pci0000:00/0000:00:01.2/0000:02:00.0/0000:02:00.0/0000:02:00.0_IPCR
...
That's quite misleading/confusing and can cause device registering
issues because of duplicate dev name (e.g. if a PCI device register
two different MHI instances).
This patch changes MHI core to create indexed mhi controller names
(mhi0, mhi1...) in the same way as other busses (i2c0, usb0...).
The previous example becomes:
devices/pci0000:00/0000:00:01.2/0000:02:00.0/mhi0
devices/pci0000:00/0000:00:01.2/0000:02:00.0/mhi0/mhi0_IPCR
...
v2: move index field at the end of mhi_controller struct (before bool)
to avoid breaking well packed alignment.

There was a report of NULL pointer dereference in ETF enable
path for perf CS mode with PID monitoring. It is almost 100%
reproducible when the process to monitor is something very
active such as chrome and with ETF as the sink, not ETR.
But code path shows that ETB has a similar path as ETF, so
there could be possible NULL pointer dereference crash in
ETB as well. Currently in a bid to find the pid, the owner
is dereferenced via task_pid_nr() call in etb_enable_perf()
and with owner being NULL, we can get a NULL pointer
dereference, so have a similar fix as ETF where we cache PID
in alloc_buffer() callback which is called as the part of
etm_setup_aux().

There was a report of NULL pointer dereference in ETF enable
path for perf CS mode with PID monitoring. It is almost 100%
reproducible when the process to monitor is something very
active such as chrome and with ETF as the sink and not ETR.
Currently in a bid to find the pid, the owner is dereferenced
via task_pid_nr() call in tmc_enable_etf_sink_perf() and with
owner being NULL, we get a NULL pointer dereference.
Looking at the ETR and other places in the kernel, ETF and the
ETB are the only places trying to dereference the task(owner)
in tmc_enable_etf_sink_perf() which is also called from the
sched_in path as in the call trace. Owner(task) is NULL even
in the case of ETR in tmc_enable_etr_sink_perf(), but since we
cache the PID in alloc_buffer() callback and it is done as part
of etm_setup_aux() when allocating buffer for ETR sink, we never
dereference this NULL pointer and we are safe. So lets do the
same thing with ETF and cache the PID to which the cs_buffer
belongs in tmc_alloc_etf_buffer() as done for ETR. This will
also remove the unnecessary function calls(task_pid_nr()) since
we are caching the PID.
Easily reproducible running below:
perf record -e cs_etm/@tmc_etf0/ -N -p <pid>
