wifi: iwlwifi: mld: don't modify trans state where not needed
In suspend and resume flows, if we had any error we set the transport state to
'FW_ERROR' This was done to avoid sending commands when we shouldn't.
In the mentioned flows, we can have a few types of errors:
1. logic errors
2. FW is in error state (can't send commands)
3. FW is misbehaving
4. D3 handshake error
In the first, we can still talk to the firmware.
In the second - the transport already knows about the FW error, no need to tell it.
In the third - we need to treat it as any other FW misbehaviour. There is no reason
to have a special handling here.
So we only need it for the last type. Change the code to set the
tansport state to FW error only in case of a d3 handshake error.
While at it, add a comment explaining why the opmode sets the FW error
bits.

If iwl_trans_d3_resume succeeded but the hw requested a reset, this will

But the opmode doesn't really care if the resume failed or if a restart
is required. It acts the same in both cases (beside different logs, but
this can be done in iwl_trans_pcie_d3_resume)
This complicates the code for no good reason.

wifi: iwlwifi: add a new FW file numbering scheme
Firmware releases follow a "Core N" pattern, but due to some
historical accidents, the API number for a Core N has always
been N+3. That's confusing for everyone.
For future firmware releases the firmware will make new file
names that, instead of being named with the API number, will
be named with the core number. For example, for the next one
for bz/fm it'd be "iwlwifi-bz-b0-fm-c0-c99.ucode" instead of
the now expected "iwlwifi-bz-b0-fm-c0-102.ucode".
In the driver, represent that as an offset of 1000, and then
request the "c<core>" format instead of just "<api>". When
looking for older versions, skip from 1099 to 101 (which is
core 98.)

Pull arm64 updates from Catalin Marinas:
"A quick summary: perf support for Branch Record Buffer Extensions
(BRBE), typical PMU hardware updates, small additions to MTE for
store-only tag checking and exposing non-address bits to signal
handlers, HAVE_LIVEPATCH enabled on arm64, VMAP_STACK forced on.
There is also a TLBI optimisation on hardware that does not require
break-before-make when changing the user PTEs between contiguous and
non-contiguous.
More details:
Perf and PMU updates:
- Add support for new (v3) Hisilicon SLLC and DDRC PMUs
- Add support for Arm-NI PMU integrations that share interrupts
between clock domains within a given instance
- Allow SPE to be configured with a lower sample period than the
minimum recommendation advertised by PMSIDR_EL1.Interval
- Add suppport for Arm's "Branch Record Buffer Extension" (BRBE)
- Adjust the perf watchdog period according to cpu frequency changes
- Minor driver fixes and cleanups
Hardware features:
- Support for MTE store-only checking (FEAT_MTE_STORE_ONLY)
- Support for reporting the non-address bits during a synchronous MTE
tag check fault (FEAT_MTE_TAGGED_FAR)
- Optimise the TLBI when folding/unfolding contiguous PTEs on
hardware with FEAT_BBM (break-before-make) level 2 and no TLB
conflict aborts
Software features:
- Enable HAVE_LIVEPATCH after implementing arch_stack_walk_reliable()
and using the text-poke API for late module relocations
- Force VMAP_STACK always on and change arm64_efi_rt_init() to use
arch_alloc_vmap_stack() in order to avoid KASAN false positives
ACPI:
- Improve SPCR handling and messaging on systems lacking an SPCR
table
Debug:
- Simplify the debug exception entry path
- Drop redundant DBG_MDSCR_* macros
Kselftests:
- Cleanups and improvements for SME, SVE and FPSIMD tests
Miscellaneous:
- Optimise loop to reduce redundant operations in contpte_ptep_get()
- Remove ISB when resetting POR_EL0 during signal handling
- Mark the kernel as tainted on SEA and SError panic
- Remove redundant gcs_free() call"

- Standardize on the __ASSEMBLER__ macro that is provided by GCC and
Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both
uapi and non-uapi headers
- Explicitly include <linux/export.h> in architecture and driver files
which contain an EXPORT_SYMBOL() and remove the include from the
files which do not contain the EXPORT_SYMBOL()
- Use the full title of "z/Architecture Principles of Operation" manual
and the name of a section where facility bits are listed
- Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
unnecessary slowing down of the build and confusing external kABI
tools that process symtypes data
- Print additional unrecoverable machine check information to make the
root cause analysis easier
- Move cmpxchg_user_key() handling to uaccess library code, since the
generated code is large anyway and there is no benefit if it is
inlined
- Fix a problem when cmpxchg_user_key() is executing a code with a
non-default key: if a system is IPL-ed with "LOAD NORMAL", and the
previous system used storage keys where the fetch-protection bit was
set for some pages, and the cmpxchg_user_key() is located within such
page, a protection exception happens
- Either the external call or emergency signal order is used to send an
IPI to a remote CPU. Use the external order only, since it is at
least as good and sometimes even better, than the emergency signal
- In case of an early crash the early program check handler prints more
or less random value of the last breaking event address, since it is
not initialized properly. Copy the last breaking event address from
the lowcore to pt_regs to address this
- During STP synchronization check udelay() can not be used, since the
first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
return a non-monotonic time. Instead, busy-loop on other CPUs, while
the the first CPU actually handles the synchronization operation
- When debugging the early kernel boot using QEMU with the -S flag and
GDB attached, skip the decompressor and start directly in kernel
- Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
Principles of Operation" manual
- Remove the in-kernel time steering support in favour of the new s390
PTP driver, which allows the kernel clock steered more precisely
- Remove a possible false-positive warning in pte_free_defer(), which
could be triggered in a valid case KVM guest process is initializing

compiler_types: Provide __no_kstack_erase to disable coverage only on Clang
In order to support Clang's stack depth tracking (for Linux's kstack_erase
feature), the coverage sanitizer needed to be disabled for __init (and
__head) section code. Doing this universally (i.e. for GCC too) created
a number of unexpected problems, ranging from changes to inlining logic
to failures to DCE code on earlier GCC versions.
Since this change is only needed for Clang, specialize it so that GCC
doesn't see the change as it isn't needed there (the GCC implementation
of kstack_erase uses a GCC plugin that removes stack depth tracking
instrumentation from __init sections during a late pass in the IR).
Successfully build and boot tested with GCC 12 and Clang 22.

Pull timekeeping and VDSO updates from Thomas Gleixner:
- Introduce support for auxiliary timekeepers
PTP clocks can be disconnected from the universal CLOCK_TAI reality
for various reasons including regularatory requirements for
functional safety redundancy.
The kernel so far only supports a single notion of time, which means
that all clocks are correlated in frequency and only differ by offset
to each other.
Access to non-correlated PTP clocks has been available so far only
through the file descriptor based "POSIX clock IDs", which are
subject to locking and have to go all the way out to the hardware.
The access is not only horribly slow, as it has to go all the way out
to the NIC/PTP hardware, but that also prevents the kernel to read
the time of such clocks e.g. from the network stack, where it is
required for TSN networking both on the transmit and receive side
unless the hardware provides offloading.
The auxiliary clocks provide a mechanism to support arbitrary clocks
which are not correlated to the system clock. This is not restricted
to the PTP use case on purpose as there is no kernel side association
of these clocks to a particular PTP device because that's a pure user
space configuration decision. Having them independent allows to
utilize them for other purposes and also enables them to be tested
without hardware dependencies.
To avoid pointless overhead these clocks have to be enabled
individualy via a new sysfs interface to reduce the overhead to a
single compare in the hotpath if they are enabled at the Kconfig
level at all.
These clocks utilize the existing timekeeping/NTP infrastructures,
which has been made possible over the recent releases by incrementaly
converting these infrastructures over from a single static instance
to a multi-instance pointer based implementation without any
performance regression reported.
The auxiliary clocks provide the same "emulation" of a "correct"
clock as the existing CLOCK_* variants do with an independent
instance of data and provide the same steering mechanism through the
existing sys_clock_adjtime() interface, which has been confirmed to
work by the chronyd(8) maintainer.
That allows to provide lockless kernel internal and VDSO support so
that applications and kernel internal functionalities can access
these clocks without restrictions and at the same performance as the
existing system clocks.
- Avoid double notifications in the adjtimex() syscall. Not a big
issue, but a trivial to avoid latency source.

IMSIC. Unfortunatly this is required because there is no mechanism
available to discover this programatically.

Pull irq updates from Thomas Gleixner:
- Prevent a interrupt migration related live lock in handle_edge_irq()
If the interrupt affinity is moved to a new target CPU and the
interrupt is currently handled on the previous target CPU for edge
type interrupts the handler might get stuck on the previous target
for a long time, which causes both involved CPUs to waste cycles and
eventually run into a soft-lockup situation.
Solve this by checking whether the interrupt is redirected to a new
target CPU and if the interrupt is handled on that new target CPU,
busy wait for completion instead of masking it and sending the
pending but which would cause the old CPU to re-run the handler and
in the worst case repeating this excercise for a long time.
This only works on architectures which use single CPU interrupt
targets, but that's so far the only ones where this behaviour has
been observed.
- Add a kunit test for interrupt disable depth counts
The nested interrupt disable depth has been an issue in the past
especially vs. free_irq(), interrupt shutdown and CPU hotplug and
their interactions. The test exercises the combinations of these
scenarios and checks for correctness.

Pull new SoC support from Arnd Bergmann:
"These five newly supported chips come with both devicetree
descriptions and the changes to wire them up to the build system for
easier bisection.
The chips in question are:
- Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
in the product line that started with the Digital StrongARM SA1100
based PDAs and continued with the Intel PXA2xx that dominated early
smartphones. This one only made it only into a few products before
the entire product line was cut in 2015.
- The QiLai SoC is made by RISC-V core designer Andes Technologies
and is in the 'Voyager' reference board in MicroATX form factor. It
uses four in-order AX45MP cores, which is the midrange product from
Andes.
- CIX P1 is one of the few Arm chips designed for small workstations,
and this one uses 12 Cortex-A720/A520 cores, making it also one of
the only ARMv9.2 machines that one can but at the moment.
- Axiado AX3000 is an embedded chip with relative small Cortex-A53
CPU cores described as a "Trusted Control/Compute Unit" that can be
used as a BMC in servers. In addition to the usual I/O, this one
comes with 10GBit ethernet and and a 4TOPS NPU.
- Sophgo SG2000 is an embedded chip that comes with both RISC-V and
Arm cores that can run Linux. This was already supported for RISC-V
but now it also works on Arm
One more chip, the Black Sesame C1200 did not make it in tirm for the
merge window"

Pull SoC driver updates from Arnd Bergmann:
"Changes are all over the place, but very little sticks out as
noteworthy.
There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
I/O chip, along with hooking it up to the pinctrl and clk frameworks.
The reset controller and memory subsystems have mainly small updates,
but there are two new reset drivers for the K230 and VC1800B SoCs, and
new memory driver support for Tegra264.
The ARM SMCCC and SCMI firmware drivers gain a few more features that
should help them be supported across more environments. Similarly, the
SoC specific firmware on Tegra and Qualcomm get minor enhancements and
chip support.
In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
grow to support more chips, while the Hisilicon, Mediatek and Renesas
drivers see mostly janitorial fixes"

Major things that stand out are:
- gpib cleanups and tweaks with the majority of the big issues now
taken care of. Odds are it will move out of staging/ in the next
merge window if all goes well.
- more constant cleanups and layer removals from the rtl8723bs
driver. It's amazing how many layers deep they really are, all
cleanups here are great to see
- axis-fifo sysfs api removed and debugfs api added. The sysfs api
didn't work at all so obviously no one was using it. Add the same
information into debugfs as that's the proper place for it, and
make it actually work.
- Remaining changes is lots of small checkpatch cleanups, most of
which seem to have come from a Debconf session where people were
encouraged to submit their first kernel patch, a nice thing to see
happen again.
