Several serieses of fixes that have come in since the merge window,

use 16 bit rather than 32 bit DMIC configuration blobs in their firmware

some smaller single patch fixes.

It's slightly better to set _GNU_SOURCE in the source code, but if one
must do it via the compiler invocation, then the best way to do so is
this:
$(CC) -D_GNU_SOURCE=
...because otherwise, if this form is used:
$(CC) -D_GNU_SOURCE
...then that leads the compiler to set a value, as if you had passed in:
$(CC) -D_GNU_SOURCE=1
That, in turn, leads to warnings under both gcc and clang, like this:
futex_requeue_pi.c:20: warning: "_GNU_SOURCE" redefined
Fix this by using the "-D_GNU_SOURCE=" form.

There are multiple assertion formatting functions in the `assert.c`
file, which are not covered with tests yet. Implement the KUnit test
for these functions.
The test consists of 11 test cases for the following functions:
1) 'is_literal'
2) 'is_str_literal'
3) 'kunit_assert_prologue', test case for multiple assert types
4) 'kunit_assert_print_msg'
5) 'kunit_unary_assert_format'
6) 'kunit_ptr_not_err_assert_format'
7) 'kunit_binary_assert_format'
8) 'kunit_binary_ptr_assert_format'
9) 'kunit_binary_str_assert_format'
10) 'kunit_assert_hexdump'
11) 'kunit_mem_assert_format'
The test aims at maximizing the branch coverage for the assertion
formatting functions.
As you can see, it covers some of the static helper functions as
well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT'
and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the
corresponding definitions to `assert.h`.
Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to
how it is done for the string stream test.

Ricky reports that replacing a device in a hotplug slot during ACPI sleep
state S3 does not cause re-enumeration on resume, as one would expect.
Instead, the new device is treated as if it was the old one.
There is no bulletproof way to detect device replacement, but as a
heuristic, check whether the device identity in config space matches cached
data in struct pci_dev (Vendor ID, Device ID, Class Code, Revision ID,
Subsystem Vendor ID, Subsystem ID). Additionally, cache and compare the
Device Serial Number (PCIe r6.2 sec 7.9.3). If a mismatch is detected,
mark the old device disconnected (to prevent its driver from accessing the
new device) and synthesize a Presence Detect Changed event.
The device identity in config space which is compared here is the same as
the one included in the signed Subject Alternative Name per PCIe r6.1 sec
6.31.3. Thus, the present commit prevents attacks where a valid device is
replaced with a malicious device during system sleep and the valid device's
driver obliviously accesses the malicious device.
This is about as much as can be done at the PCI layer. Drivers may have
additional ways to identify devices (such as reading a WWID from some
register) and may trigger re-enumeration when detecting an identity change
on resume.

In general a read fills 4kb so filling the buffer is a 1 in 4096
operation, move it out of the io__get_char function to avoid some

Top of the kernel thread stack should be reserved for pt_regs. However
this is not the case for the idle threads of the secondary boot harts.
Their stacks overlap with their pt_regs, so both may get corrupted.
Similar issue has been fixed for the primary hart, see c7cdd96eca
("riscv: prevent stack corruption by reserving task_pt_regs(p) early").
However that fix was not propagated to the secondary harts. The problem
has been noticed in some CPU hotplug tests with V enabled. The function
smp_callin stored several registers on stack, corrupting top of pt_regs
structure including status field. As a result, kernel attempted to save
or restore inexistent V context.

ERETAx can fail in multiple ways:
(1) ELR_EL2 points lalaland
(2) we get a PAC failure
(3) SPSR_EL2 has the wrong mode
(1) is easy, as we just let the CPU do its thing and deliver an
Instruction Abort. However, (2) and (3) are interesting, because
the PAC failure priority is way below that of the Illegal Execution
State exception.
Which means that if we have detected a PAC failure (and that we have
FPACCOMBINE), we must be careful to give priority to the Illegal
Execution State exception, should one be pending.
Solving this involves hoisting the SPSR calculation earlier and
testing for the IL bit before injecting the FPAC exception.
In the extreme case of a ERETAx returning to an invalid mode *and*
failing its PAC check, we end up with an Instruction Abort (due
to the new PC being mangled by the failed Auth) *and* PSTATE.IL
being set. Which matches the requirements of the architecture.
Whilst we're at it, remove a stale comment that states the obvious
and only confuses the reader.

Currently we do reset for each RDDM event from MHI, however there are
cases, see below log, that we get two or more consecutive events, and
it is pointless to do reset for the subsequent ones. What's more, it
makes reset process more likely to fail.
[ 103.289864] mhi mhi0: System error detected
[ 103.289871] ath12k_pci 0000:03:00.0: mhi notify status reason MHI_CB_EE_RDDM

[ 103.293150] ath12k_pci 0000:03:00.0: mhi notify status reason MHI_CB_EE_RDDM
Add a check to avoid reset again and again. This is done by tracking previous
MHI status: if we receive a new RDDM event while the previous event is
also the same, we treat it as duplicate and ignore it, because normally
we should at least receive a MHI_CB_EE_MISSION_MODE event between them.

tl;dr: CPUs with CPUID.80000008H but without CPUID.01H:EDX[CLFSH]
will end up reporting cache_line_size()==0 and bad things happen.
Fill in a default on those to avoid the problem.
Long Story:
The kernel dies a horrible death if c->x86_cache_alignment (aka.
cache_line_size() is 0. Normally, this value is populated from
c->x86_clflush_size.
Right now the code is set up to get c->x86_clflush_size from two
places. First, modern CPUs get it from CPUID. Old CPUs that don't
have leaf 0x80000008 (or CPUID at all) just get some sane defaults
from the kernel in get_cpu_address_sizes().
The vast majority of CPUs that have leaf 0x80000008 also get
->x86_clflush_size from CPUID. But there are oddballs.
Intel Quark CPUs[1] and others[2] have leaf 0x80000008 but don't set
CPUID.01H:EDX[CLFSH], so they skip over filling in ->x86_clflush_size:
cpuid(0x00000001, &tfms, &misc, &junk, &cap0);
if (cap0 & (1<<19))
c->x86_clflush_size = ((misc >> 8) & 0xff) * 8;
So they: land in get_cpu_address_sizes() and see that CPUID has level
0x80000008 and jump into the side of the if() that does not fill in
c->x86_clflush_size. That assigns a 0 to c->x86_cache_alignment, and
hilarity ensues in code like:
buffer = kzalloc(ALIGN(sizeof(*buffer), cache_line_size()),
GFP_KERNEL);
To fix this, always provide a sane value for ->x86_clflush_size.
Big thanks to Andy Shevchenko for finding and reporting this and also
providing a first pass at a fix. But his fix was only partial and only
worked on the Quark CPUs. It would not, for instance, have worked on
the QEMU config.

2. You can also get this behavior if you use "-cpu 486,+clzero"
in QEMU.

Invalid csi2 port will break the isys notifier bound ops as it is
trying to access an invalid csi2 sub-device instance based on the

kmemleak shows that there is a memory leak in io_uring read operation,
where a buffer is allocated at iovec import, but never de-allocated.
The memory is allocated at io_async_rw->free_iovec, but, then
io_async_rw is kfreed, taking the allocated memory with it. I saw this
happening when the read operation fails with -11 (EAGAIN).
This is the kmemleak splat.

This occurs because the async data cleanup functions are not set for
read/write operations. As a result, the potentially allocated iovec in
the rw async data is not freed before the async data is released,
leading to a memory leak.
With this following patch, kmemleak does not show the leaked memory
anymore, and all liburing tests pass.

The new AMD/HYGON topology parser evaluates the SMT information in CPUID leaf
0x8000001e unconditionally while the original code restricted it to CPUs with
family 0x17 and greater.
This breaks family 0x15 CPUs which advertise that leaf and have a non-zero
value in the SMT section. The machine boots, but the scheduler complains loudly
about the mismatch of the core IDs:

MD Danish Anwar says:
====================
Introduce switch mode support for ICSSG driver
This series adds support for switch-mode for ICSSG driver. This series
also introduces helper APIs to configure firmware maintained FDB
(Forwarding Database) and VLAN tables. These APIs are later used by ICSSG
driver in switch mode.
Now the driver will boot by default in dual EMAC mode. When first ICSSG
interface is added to bridge driver will still be in EMAC mode. As soon as
second ICSSG interface is added to same bridge, switch-mode will be
enabled and switch firmwares will be loaded to PRU cores. The driver will
remain in dual EMAC mode if ICSSG interfaces are added to two different
bridges or if two different interfaces (One ICSSG, one other) is added to
the same bridge. We'll only enable is_switch_mode flag when two ICSSG
interfaces are added to same bridge.
We start in dual MAC mode. Let's say lan0 and lan1 are ICSSG interfaces
ip link add name br0 type bridge
ip link set lan0 master br0
At this point, we get a CHANGEUPPER event. Only one port is a member of
the bridge, so we will still be in dual MAC mode.
ip link set lan1 master br0
We get a second CHANGEUPPER event, the second interface lan1 is also ICSSG
interface so we will set the is_switch_mode flag and when interfaces are
brought up again, ICSSG switch firmwares will be loaded to PRU Cores.
There are some other cases to consider as well.
ip link add name br0 type bridge
ip link add name br1 type bridge
ip link set lan0 master br0
ip link set ppp0 master br0
Here we are adding lan0 (ICSSG) and ppp0 (non ICSSG) to same bridge, as
they both are not ICSSG, we will still be running in dual EMAC mode.
ip link set lan1 master br1
ip link set vpn0 master br1
Here we are adding lan1 (ICSSG) and vpn0 (non ICSSG) to same bridge, as
they both are not ICSSG, we will still be running in dual EMAC mode.
This is v6 of the series.
Changes from v5 to v6:
*) Removed __packed from structures in icssg_config.h file.
*) Added RB tags of Andrew Lunn <andrew@lunn.ch> to patch 2/3 and patch
3/3 of this series.
Changes from v4 to v5:
*) Rebased on 6.10-rc1.
*) Dropped the RFC tag.
Changes from v3 to v4:
*) Added RFC tag as net-next is closed now.
*) Modified the driver to remove the need of bringing interfaces up / down
for enabling / disabling switch mode. Now switch mode can be enabled
without bringig interfaces up / down as requested by Andrew Lunn
<andrew@lunn.ch>
*) Modified commit message of patch 3/3.
Changes from v2 to v3:
*) Dropped RFC tag.
*) Used ether_addr_copy() instead of manually copying mac address using
for loop in patch 1/3 as suggested by Andrew Lunn <andrew@lunn.ch>
*) Added helper API icssg_fdb_setup() in patch 1/3 to reduce code
duplication as suggested by Andrew Lunn <andrew@lunn.ch>
*) In prueth_switchdev_stp_state_set() removed BR_STATE_LEARNING as
learning without forwarding is not supported by ICSSG firmware.
*) Used ether_addr_equal() wherever possible in patch 2/3 as suggested
by Andrew Lunn <andrew@lunn.ch>
*) Fixed typo "nit: s/prueth_switchdevice_nb/prueth_switchdev_nb/" in
patch 2/3 as suggested by Simon Horman <horms@kernel.org>
*) Squashed "#include "icssg_mii_rt.h" to patch 2/3 from patch 3/3 as
suggested by Simon Horman <horms@kernel.org>
*) Rebased on latest net-next/main.
Changes from v1 to v2:
*) Removed TAPRIO support patch from this series.
*) Stopped using devlink for enabling switch-mode as suggested by Andrew L
*) Added read_poll_timeout() in patch 1 / 3 as suggested by Andrew L.

Add support for ICSSG switch firmware using existing Dual EMAC driver
with switchdev.
Limitations:
VLAN offloading is limited to 0-256 IDs.
MDB/FDB static entries are limited to 511 entries and different FDBs can
hash to same bucket and thus may not completely offloaded
Example assuming ETH1 and ETH2 as ICSSG2 interfaces:
Switch to ICSSG Switch mode:
ip link add name br0 type bridge
ip link set dev eth1 master br0
ip link set dev eth2 master br0
ip link set dev br0 up
bridge vlan add dev br0 vid 1 pvid untagged self
Going back to Dual EMAC mode:
ip link set dev br0 down
ip link set dev eth1 nomaster
ip link set dev eth2 nomaster
ip link del name br0 type bridge
By default, Dual EMAC firmware is loaded, and can be changed to switch
mode by above steps

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The existing logic to pick a DMIC blob is based on several historical
assumptions that the NHLT in BIOS always contains 32-bits per sample
type (first patch, [1]).
The other issue with the existing logic is that it was designed to care only
about the bit depth of the format and fails to find the existing and correct
blob when rate/channels are different on the FE side compared to what we should
be using on the DAI side (we have components in path which can change
rate/channel count).
These issues have not been observed in past but with new MTL based (Windows)
laptops and new topologies to enhance the audio quality, we started to see weird
issues around how our assumptions of vendors failed.
Since some NHLT blob handling cleanup has been done for 6.10, this series will
complete that work to cover even cases that we don't anticipate to see.
