When FORTIFY_SOURCE reports about a run-time buffer overread, the wrong
buffer size was being shown in the error message. (The bounds checking
was correct.)
Fixes: 3d965b33e40d ("fortify: Improve buffer overflow reporting")

Certain targets disable kstack_erase by filtering out KSTACK_ERASE_CFLAGS
rather than adding DISABLE_KSTACK_ERASE. The renaming to kstack_erase
missed the CFLAGS export, which broke those build targets (e.g. x86
vdso32).
Fixes: 76261fc7d1be ("stackleak: Split KSTACK_ERASE_CFLAGS from GCC_PLUGINS_CFLAGS")

Pull x86 CPU mitigation updates from Borislav Petkov:
- Untangle the Retbleed from the ITS mitigation on Intel. Allow for ITS
to enable stuffing independently from Retbleed, do some cleanups to
simplify and streamline the code
- Simplify SRSO and make mitigation types selection more versatile
depending on the Retbleed mitigation selection. Simplify code some
- Add the second part of the attack vector controls which provide a lot
friendlier user interface to the speculation mitigations than
selecting each one by one as it is now.
Instead, the selection of whole attack vectors which are relevant to
the system in use can be done and protection against only those
vectors is enabled, thus giving back some performance to the users

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.

Pull timer cleanups from Thomas Gleixner:
"A treewide cleanup of struct cycle_counter const annotations.
The initial idea of making them const was correct as they were
seperate instances. When they got embedded into larger data
structures, which are even modified by the callback this got moot. The
only reason why this went unnoticed is that the required
container_of() casts the const attribute forcefully away.
Stop pretending that it is const"

Pull interrupt chip driver updates from Thomas Gleixner:
- Add support of forced affinity setting to yet offline CPUs for the
MIPS-GIC to ensure that the affinity of per CPU interrupts can be set
during the early bringup phase of a secondary CPU in the hotplug code
before the CPU is set online and interrupts are enabled
- Add support for the MIPS (RISC-V !?!?) P8700 SoC in the ACLINT_SSWI
interrupt chip
- Make the interrupt routing to RISV-V harts specification compliant so
it supports arbitrary hart indices
- Add a command line parameter and related handling to disable the
generic RISCV IMSIC mechanism on platforms which use a trap-emulated
IMSIC. Unfortunatly this is required because there is no mechanism
available to discover this programatically.
- Enable wakeup sources on the Renesas RZV2H driver
- Convert interrupt chip drivers, which use a open coded variant of
msi_create_parent_irq_domain() to use the new functionality
- Convert interrupt chip drivers, which use the old style two level
implementation of MSI support over to the MSI parent mechanism to
prepare for removing at least one of the three PCI/MSI backend
variants.

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.

"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

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.

Pull SoC devicetree updates from Arnd Bergmann:
"There are a few new variants of existing chips:
- mt6572 is an older mobile phone chip from mediatek that was
extremely popular a decade ago but never got upstreamed until now
- exynos2200 is a recent high-end mobile phone chip used in a few
Samsung phones like the Galaxy S22
- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it
There are five more chips in a separate branch, as those are new chip
families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly added
machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and Sophgo
sg2042
- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95
- Two newly added ASPEED BMC based motherboards, and one that got
removed
- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm
Updates for existing machines are spread over all the above families.
One notable change here is support for the RP1 I/O chip used in
Raspberry Pi 5"

make it actually work.

KVM/arm64 changes for 6.17, round #1
- Host driver for GICv5, the next generation interrupt controller for
arm64, including support for interrupt routing, MSIs, interrupt
translation and wired interrupts.
- Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
GICv5 hardware, leveraging the legacy VGIC interface.
- Userspace control of the 'nASSGIcap' GICv3 feature, allowing
userspace to disable support for SGIs w/o an active state on hardware
that previously advertised it unconditionally.
- Map supporting endpoints with cacheable memory attributes on systems
with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
maintenance on the address range.
- Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
hypervisor to inject external aborts into an L2 VM and take traps of
masked external aborts to the hypervisor.
- Convert more system register sanitization to the config-driven
implementation.
- Fixes to the visibility of EL2 registers, namely making VGICv3 system
registers accessible through the VGIC device instead of the ONE_REG
vCPU ioctls.
- Various cleanups and minor fixes.

As per the i.MX93 TRM, section 67.3.2.1 "MOD register update", the value
of the TPM counter does NOT get updated when writing MOD.MOD unless
SC.CMOD != 0. Therefore, with the current code, assuming the following
sequence:
1) pwm_disable()
2) pwm_apply_might_sleep() /* period is changed here */
3) pwm_enable()
and assuming only one channel is active, if CNT.COUNT is higher than the
MOD.MOD value written during the pwm_apply_might_sleep() call then, when
re-enabling the PWM during pwm_enable(), the counter will end up resetting
after UINT32_MAX - CNT.COUNT + MOD.MOD cycles instead of MOD.MOD cycles as
normally expected.
Fix this problem by forcing a reset of the TPM counter before MOD.MOD is
written.

The period generated by the hardware is
(PWMDWIDTH + 1) << CLKDIV) / freq
according to my tests with a signal analyser and also the documentation.
The current algorithm doesn't consider the `+ 1` part and so configures
slightly too high periods. The same issue exists for the duty cycle
setting. So subtract 1 from both the register values for period and
duty cycle. If period is 0, bail out, if duty_cycle is 0, just disable
the PWM which results in a constant low output.

Stop handling the clocks in pwm_mediatek_enable() and
pwm_mediatek_disable(). This is a preparing change for the next commit
that requires that clocks and the enable bit are handled separately.
Also move these two functions a bit further up in the source file to
make them usable in pwm_mediatek_config(), which is needed in the next

In dbAllocCtl(), read_metapage() increases the reference count of the
metapage. However, when dp->tree.budmin < 0, the function returns -EIO
without calling release_metapage() to decrease the reference count,
leading to a memory leak.
Add release_metapage(mp) before the error return to properly manage
the metapage reference count and prevent the leak.
