Pull ARM SoC updates from Arnd Bergmann:
"Almost all SoC code changes this time are for the TI OMAP platform,
which continues its decade-long quest to move from describing a
complex SoC in code to device tree.
Aside from this, the Uniphier platform has a new maintainer and some
platforms have minor bugfixes and cleanups that were not urgent enough
for v5.12"

shows up with this hardware, it is trivial to restore these but we
really do not think they are in use anymore.

Pull staging/IIO driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for this
failed "experiment".
- removal of the Google gasket driver, turns out no one wanted to
maintain it or cares about it anymore, so they asked for it to be
removed.
- comedi finally moves out of the staging directory into drivers/comedi
This is one of the oldest kernel subsystems around, being created
in the 2.0 kernel days, and was one of the first things added to
drivers/staging/ when that was created over 15 years ago.
It should have been moved out of staging a long time ago, it's well
maintained and used by loads of different devices in the real world
every day. Nice to see this finally happen.
- so many tiny coding style cleanups it's not funny.
Perfect storm of at least 2 different intern project application
deadlines combined to provide a huge number of new contributions in
this area from people learning how to do kernel development. Great
job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers
and updates all over that subsystem.

Pull arm64 updates from Catalin Marinas:
- MTE asynchronous support for KASan. Previously only synchronous
(slower) mode was supported. Asynchronous is faster but does not
allow precise identification of the illegal access.
- Run kernel mode SIMD with softirqs disabled. This allows using NEON
in softirq context for crypto performance improvements. The
conditional yield support is modified to take softirqs into account
and reduce the latency.
- Preparatory patches for Apple M1: handle CPUs that only have the VHE
mode available (host kernel running at EL2), add FIQ support.
- arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers,
new functions for the HiSilicon HHA and L3C PMU, cleanups.
- Re-introduce support for execute-only user permissions but only when
the EPAN (Enhanced Privileged Access Never) architecture feature is
available.
- Disable fine-grained traps at boot and improve the documented boot
requirements.
- Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).
- Add hierarchical eXecute Never permissions for all page tables.
- Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
to control which PAC keys are enabled in a particular task.

Pull entry code update from Thomas Gleixner:
"Provide support for randomized stack offsets per syscall to make
stack-based attacks harder which rely on the deterministic stack
layout.
The feature is based on the original idea of PaX's RANDSTACK feature,
but uses a significantly different implementation.
The offset does not affect the pt_regs location on the task stack as
this was agreed on to be of dubious value. The offset is applied
before the actual syscall is invoked.
The offset is stored per cpu and the randomization happens at the end
of the syscall which is less predictable than on syscall entry.
The mechanism to apply the offset is via alloca(), i.e. abusing the
dispised VLAs. This comes with the drawback that
stack-clash-protection has to be disabled for the affected compilation
units and there is also a negative interaction with stack-protector.
Those downsides are traded with the advantage that this approach does
not require any intrusive changes to the low level assembly entry
code, does not affect the unwinder and the correct stack alignment is
handled automatically by the compiler.
The feature is guarded with a static branch which avoids the overhead
when disabled.
Currently this is supported for X86 and ARM64"

Pull irq updates from Thomas Gleixner:
"The usual updates from the irq departement:
Core changes:
- Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can
be cleaned up which either use a seperate mechanism to prevent
auto-enable at request time or have a racy mechanism which disables
the interrupt right after request.
- Get rid of the last usage of irq_create_identity_mapping() and
remove the interface.
- An overhaul of tasklet_disable().
Most usage sites of tasklet_disable() are in task context and
usually in cleanup, teardown code pathes. tasklet_disable()
spinwaits for a tasklet which is currently executed. That's not
only a problem for PREEMPT_RT where this can lead to a live lock
when the disabling task preempts the softirq thread. It's also
problematic in context of virtualization when the vCPU which runs
the tasklet is scheduled out and the disabling code has to spin
wait until it's scheduled back in.
There are a few code pathes which invoke tasklet_disable() from
non-sleepable context. For these a new disable variant which still
spinwaits is provided which allows to switch tasklet_disable() to a
sleep wait mechanism. For the atomic use cases this does not solve
the live lock issue on PREEMPT_RT. That is mitigated by blocking on
the RT specific softirq lock.
- The PREEMPT_RT specific implementation of softirq processing and
local_bh_disable/enable().
On RT enabled kernels soft interrupt processing happens always in
task context and all interrupt handlers, which are not explicitly
marked to be invoked in hard interrupt context are forced into task
context as well. This allows to protect against softirq processing
with a per CPU lock, which in turn allows to make BH disabled
regions preemptible.
Most of the softirq handling code is still shared. The RT/non-RT
specific differences are addressed with a set of inline functions
which provide the context specific functionality. The
local_bh_disable() / local_bh_enable() mechanism are obviously
seperate.
- The usual set of small improvements and cleanups
Driver changes:
- New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt

- Enhanced robustness for ARM GICv3/4.1 drivers

"First big cleanup to the paravirt infra to use alternatives and thus
eliminate custom code patching.
For that, the alternatives infrastructure is extended to accomodate
paravirt's needs and, as a result, a lot of paravirt patching code
goes away, leading to a sizeable cleanup and simplification.

In null_init, null_add_dev(dev) is called.
In null_add_dev, it calls null_free_zoned_dev(dev) to free dev->zones
via kvfree(dev->zones) in out_cleanup_zone branch and returns err.
Then null_init accept the err code and then calls null_free_dev(dev).
But in null_free_dev(dev), dev->zones is freed again by
null_free_zoned_dev().
My patch set dev->zones to NULL in null_free_zoned_dev() after
kvfree(dev->zones) is called, to avoid the double free.

In command queueing mode, the cache isn't flushed via the mmc_flush_cache()
function, but instead by issuing a CMDQ_TASK_MGMT (CMD48) with a
FLUSH_CACHE opcode. In this path, we need to check if cache has been
enabled, before deciding to flush the cache, along the lines of what's
being done in mmc_flush_cache().
To fix this problem, let's add a new bus ops callback ->cache_enabled() and
implement it for the mmc bus type. In this way, the mmc block device driver
can call it to know whether cache flushing should be done.

The value was never checked here, and the purpose of the function
is only to flush the contents, so restore the old behavior but
add a cast to void and a comment, which hopefully warns with neither
gcc nor clang now.
If anyone has an idea for how to fix it without ignoring the return
code, that is probably better.

When the PF is no longer enforcing an assigned MAC address on a VF, the
VF needs to call bnxt_approve_mac() to tell the PF what MAC address it is
now using. Otherwise it gets out of sync and the PF won't know what
MAC address the VF wants to use. Ultimately the VF will fail when it
tries to setup the L2 MAC filter for the vnic.

VF will see all packets received by the PF, irrespective of destination
MAC or VLAN.
Note, it is necessary to query firmware at the time of bnxt_promisc_ok()
instead of in bnxt_hwrm_func_qcfg() because the trusted status might be
altered by the PF after the VF has been configured. This check must now
also be deferred because the firmware call sleeps.

In the current code, the driver will not shutdown the link during
IFDOWN if there are still VFs sharing the port. Newer firmware will
manage the link down decision when the port is shared by VFs, so
we can just call firmware to shutdown the port unconditionally and
let firmware make the final decision.

Copy the phy related feature flags from the firmware call
HWRM_PORT_PHY_QCAPS to this new field. We can also remove the flags
field in the bnxt_test_info structure. It's cleaner to have all PHY
related flags in one location, directly copied from the firmware.
To keep the BNXT_PHY_CFG_ABLE() macro logic the same, we need to make
a slight adjustment to check that it is a PF.

Firmware reports link signalling mode for certain speeds. In these
cases, print the signalling modes in kernel log link up messages.

The default behavior for source MACVLAN is to duplicate packets to
appropriate type source devices, and then do the normal destination MACVLAN
flow. This patch adds an option to skip destination MACVLAN processing if
any matching source MACVLAN device has the option set.
This allows setting up a "catch all" device for source MACVLAN: create one
or more devices with type source nodst, and one device with e.g. type vepa,
and incoming traffic will be received on exactly one device.

devlink external port attribute for SF (Sub-Function) port flavour
This adds the support to instantiate Sub-Functions on external hosts
E.g when Eswitch manager is enabled on the ARM SmarNic SoC CPU, users
are now able to spawn new Sub-Functions on the Host server CPU.
Parav Pandit Says:
==================
This series introduces and uses external attribute for the SF port to
indicate that a SF port belongs to an external controller.
This is needed to generate unique phys_port_name when PF and SF numbers
are overlapping between local and external controllers.
For example two controllers 0 and 1, both of these controller have a SF.
having PF number 0, SF number 77. Here, phys_port_name has duplicate
entry which doesn't have controller number in it.
Hence, add controller number optionally when a SF port is for an
external controller. This extension is similar to existing PF and VF
eswitch ports of the external controller.
When a SF is for external controller an example view of external SF
port and config sequence:
On eswitch system:
$ devlink dev eswitch set pci/0033:01:00.0 mode switchdev
$ devlink port show
pci/0033:01:00.0/196607: type eth netdev enP51p1s0f0np0 flavour physical port 0 splittable false
pci/0033:01:00.0/131072: type eth netdev eth0 flavour pcipf controller 1 pfnum 0 external true splittable false
function:
hw_addr 00:00:00:00:00:00
$ devlink port add pci/0033:01:00.0 flavour pcisf pfnum 0 sfnum 77 controller 1
pci/0033:01:00.0/163840: type eth netdev eth1 flavour pcisf controller 1 pfnum 0 sfnum 77 splittable false
function:
hw_addr 00:00:00:00:00:00 state inactive opstate detached
phys_port_name construction:
$ cat /sys/class/net/eth1/phys_port_name
c1pf0sf77
Patch summary:
First 3 patches prepares the eswitch to handle vports in more generic
way using xarray to lookup vport from its unique vport number.
Patch-1 returns maximum eswitch ports only when eswitch is enabled
Patch-2 prepares eswitch to return eswitch max ports from a struct
Patch-3 uses xarray for vport and representor lookup
Patch-4 considers SF for an additioanl range of SF vports
Patch-5 relies on SF hw table to check SF support
Patch-6 extends SF devlink port attribute for external flag
Patch-7 stores the per controller SF allocation attributes
Patch-8 uses SF function id for filtering events
Patch-9 uses helper for allocation and free
Patch-10 splits hw table into per controller table and generic one
Patch-11 extends sf table for additional range
