git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers
Qualcomm driver updates for v5.18
This refactors the Qualcomm mdt file loader, to partially decouple it
from the SCM peripheral-authentication-service. This is needed as newer
platforms, such as the Qualcomm SM8450, require the metadata to remain
accessible to TrustZone during a longer time. This is followed by the
introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1).
It changes the way hardware version differences are handled in the LLCC
driver and introduces support for Qualcomm SM8450. While updating the dt
binding for LLCC it also introduces the missing SM8350 compatible.
The ocmem and aoss drivers gains missing put_device() calls and rpmpd
gains a missing check for kcalloc() failure.
The SPM driver is updated to avoid instantiating the SPM cpuidle devices
if the CPUs aren't controlled by SPM, such as when Snapdragon 8916
operates in 32-bit mode without PSCI.
The RPM power-domain driver gains MSM8226 support.
Lastly the socinfo driver gains knowledge about a few new SoCs and
PMICs.

Problem:
Some directory vxattrs (e.g. ceph.dir.pin.random) are governed by
information that isn't necessarily shared with the client. Add support
for the new GETVXATTR operation, which allows the client to query the
MDS directly for vxattrs.
When the client is queried for a vxattr that doesn't have a special
handler, have it issue a GETVXATTR to the MDS directly.
Solution:
Adds new getvxattr op to fetch ceph.dir.pin*, ceph.dir.layout* and
ceph.file.layout* vxattrs.
If the entire layout for a dir or a file is being set, then it is
expected that the layout be set in standard JSON format. Individual
field value retrieval is not wrapped in JSON. The JSON format also
applies while setting the vxattr if the entire layout is being set in
one go.
As a temporary measure, setting a vxattr can also be done in the old
format. The old format will be deprecated in the future.

This expands generic branch type classification by adding two more entries
there in i.e irq and exception return. Also updates the x86 implementation
to process X86_BR_IRET and X86_BR_IRQ records as appropriate. This changes
branch types reported to user space on x86 platform but it should not be a
problem. The possible scenarios and impacts are enumerated here.

TASK_RTLOCK_WAIT currently isn't part of TASK_REPORT, thus a task blocking
on an rtlock will appear as having a task state == 0, IOW TASK_RUNNING.
The actual state is saved in p->saved_state, but reading it after reading
p->__state has a few issues:
o that could still be TASK_RUNNING in the case of e.g. rt_spin_lock
o ttwu_state_match() might have changed that to TASK_RUNNING
As pointed out by Eric, adding TASK_RTLOCK_WAIT to TASK_REPORT implies
exposing a new state to userspace tools which way not know what to do with
them. The only information that needs to be conveyed here is that a task is
waiting on an rt_mutex, which matches TASK_UNINTERRUPTIBLE - there's no
need for a new state.

As of commit
c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
the following sequence becomes possible:
p->__state = TASK_INTERRUPTIBLE;
__schedule()
deactivate_task(p);
ttwu()
READ !p->on_rq
p->__state=TASK_WAKING
trace_sched_switch()
__trace_sched_switch_state()
task_state_index()
return 0;
TASK_WAKING isn't in TASK_REPORT, so the task appears as TASK_RUNNING in
the trace event.
Prevent this by pushing the value read from __schedule() down the trace
event.

HID_QUIRK_INVERT is kind of complex to deal with and was bogus.
Furthermore, it didn't make sense to use a global per struct hid_device
quirk for something dynamic as the current state.
Store the current tool information in the report itself, and re-order
the processing of the fields to enforce having all the tablet "state"
fields before getting to In Range and other input fields.
This way, we now have all the information whether a tool is present
or not while processing In Range.
This new behavior enforces that only one tool gets forwarded to userspace
at the same time, and that if either eraser or invert is set, we enforce
BTN_TOOL_RUBBER.
Note that the release of the previous tool now happens in its own EV_SYN
report so userspace doesn't get confused by having 2 tools.
These changes are tested in the following hid-tools regression tests:

When a device exposes both Invert and InRange, Invert must be processed
before InRange. If we keep the order of the device and we process them
out of order, InRange will first set BTN_TOOL_PEN, and then Invert will
set BTN_TOOL_RUBBER. Userspace knows how to deal with that situation,
but fixing it in the kernel is now easier.

This will be used in a later commit:
we build a list of input fields (and usage_index) that is ordered based
on a usage priority.
Changing the usage priority allows to re-order the processed list, meaning
that we can enforce some usages to be process before others.
For instance, before processing InRange in the HID tablets, we need to
know if we are using the eraser (side or button). Enforcing a higher
(lower number) priority for Invert allows to force the input stack to
process that field before.

Remove the generic kvm_reload_remote_mmus() and open code its
functionality into the two x86 callers. x86 is (obviously) the only
architecture that uses the hook, and is also the only architecture that
uses KVM_REQ_MMU_RELOAD in a way that's consistent with the name. That
will change in a future patch, as x86's usage when zapping a single
shadow page x86 doesn't actually _need_ to reload all vCPUs' MMUs, only
MMUs whose root is being zapped actually need to be reloaded.
s390 also uses KVM_REQ_MMU_RELOAD, but for a slightly different purpose.
Drop the generic code in anticipation of implementing s390 and x86 arch
specific requests, which will allow dropping KVM_REQ_MMU_RELOAD entirely.
Opportunistically reword the x86 TDP MMU comment to avoid making
references to functions (and requests!) when possible, and to remove the
rather ambiguous "this".
No functional change intended.

This patch adds vnifiltering support to collect metadata device.
Motivation:
You can only use a single vxlan collect metadata device for a given
vxlan udp port in the system today. The vxlan collect metadata device
terminates all received vxlan packets. As shown in the below diagram,
there are use-cases where you need to support multiple such vxlan devices in
independent bridge domains. Each vxlan device must terminate the vni's
it is configured for.
Example usecase: In a service provider network a service provider
typically supports multiple bridge domains with overlapping vlans.
One bridge domain per customer. Vlans in each bridge domain are
mapped to globally unique vxlan ranges assigned to each customer.
vnifiltering support in collect metadata devices terminates only configured
vnis. This is similar to vlan filtering in bridge driver. The vni filtering
capability is provided by a new flag on collect metadata device.
In the below pic:
- customer1 is mapped to br1 bridge domain
- customer2 is mapped to br2 bridge domain
- customer1 vlan 10-11 is mapped to vni 1001-1002
- customer2 vlan 10-11 is mapped to vni 2001-2002
- br1 and br2 are vlan filtering bridges
- vxlan1 and vxlan2 are collect metadata devices with
vnifiltering enabled

With this implementation, vxlan dst metadata device can
be associated with range of vnis.
struct vxlan_vni_node is introduced to represent
a configured vni. We start with vni and its
associated remote_ip in this structure. This
structure can be extended to bring in other
per vni attributes if there are usecases for it.
A vni inherits an attribute from the base vxlan device
if there is no per vni attributes defined.
struct vxlan_dev gets a new rhashtable for
vnis called vxlan_vni_group. vxlan_vnifilter.c
implements the necessary netlink api, notifications
and helper functions to process and manage lifecycle
of vxlan_vni_node.
This patch also adds new helper functions in vxlan_multicast.c
to handle per vni remote_ip multicast groups which are part
of vxlan_vni_group.

mlx5-next 2022-22-02
The following PR includes updates to mlx5-next branch:
Headlines:
==========
1) Jakub cleans up unused static inline functions
2) I did some low level firmware command interface return status changes to
provide the caller with full visibility on the error/status returned by
the Firmware.
3) Use the new command interface in RDMA DEVX usecases to avoid flooding
dmesg with some "expected" user error prone use cases.
4) Moshe also uses the new command interface to grab the specific error
code from MFRL register command to provide the exact error reason for
why SW reset couldn't perform internally in FW.
5) From Mark Bloch: Lag, drop packets in hardware when possible
In active-backup mode the inactive interface's packets are dropped by the
bond device. In switchdev where TC rules are offloaded to the FDB
this can lead to packets being hit in the FDB where without offload
they would have been dropped before reaching TC rules in the kernel.
Create a drop rule to make sure packets on inactive ports are dropped
before reaching the FDB.
Listen on NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA events and record
the inactive state and offload accordingly.

Netfilter assumes its called with rcu_read_lock held, but in egress
hook case it may be called with BH readlock.
This triggers lockdep splat.
In order to avoid to change all rcu_dereference() to
rcu_dereference_check(..., rcu_read_lock_bh_held()), wrap nf_hook_slow
with read lock/unlock pair.

Pull ARM SoC fixes from Arnd Bergmann:
"The code changes address mostly minor problems:
- Several NXP/FSL SoC driver fixes, addressing issues with error
handling and compilation
- Fix a clock disabling imbalance in gpcv2 driver.
- Arm Juno DMA coherency issue
- Trivial firmware driver fixes for op-tee and scmi firmware
The remaining changes address issues in the devicetree files:
- A timer regression for the OMAP devkit8000, which has to use the
alternative timer.
- A hang in the i.MX8MM power domain configuration
- Multiple fixes for the Rockchip RK3399 addressing issues with sound
and eMMC
- Cosmetic fixes for i.MX8ULP, RK3xxx, and Tegra124"

Define a generic UART_LCR_WLEN() macro with a size argument. It can be
used to encode byte size into an LCR value. Therefore we can use it to
simplify the drivers using tty_get_char_size() in the next patches.

====================
spi: Make remove() return void
This series from Uwe Kleine-König converts the spi remove function to
return void since there is nothing useful that we can do with a failure
and it as more buses are converted it'll enable further work on the
driver core.

Initial support for the RPC_AUTH_TLS authentication flavor enables
NFSD to eventually accept an RPC_AUTH_TLS probe from clients. This
patch simply prevents NFSD from rejecting these probes completely.
In the meantime, graft this support in now so that RPC_AUTH_TLS
support keeps up with generic code and API changes in the RPC
server.
Down the road, server-side transport implementations will populate
xpo_start_tls when they can support RPC-with-TLS. For example, TCP
will eventually populate it, but RDMA won't.

A random sample of kthread_create() callers shows sunrpc is the only
one that manages module reference count in this way.

svc_close_net(). Replace all external call sites.
svc_close_net() is renamed to be the inverse of svc_xprt_create().

Clean up. Neil observed that "any code that calls svc_shutdown_net()
knows what the shutdown function should be, and so can call it
directly."

We have never been able to track down and address the underlying
cause of the performance issues with workqueue-based service
support. svo_enqueue_xprt is called multiple times per RPC, so
it adds instruction path length, but always ends up at the same
function: svc_xprt_do_enqueue(). We do not anticipate needing
this flexibility for dynamic nfsd thread management support.
As a micro-optimization, remove .svo_enqueue_xprt because
Spectre/Meltdown makes virtual function calls more costly.
This change essentially reverts commit b9e13cdfac70 ("nfsd/sunrpc:
turn enqueueing a svc_xprt into a svc_serv operation").
