sched/mmcid: Don't assume CID is CPU owned on mode switch
Shinichiro reported a KASAN UAF, which is actually an out of bounds access
in the MMCID management code.
CPU0 CPU1
T1 runs in userspace
T0: fork(T4) -> Switch to per CPU CID mode
fixup() set MM_CID_TRANSIT on T1/CPU1
T4 exit()
T3 exit()
T2 exit()
T1 exit() switch to per task mode
---> Out of bounds access.
As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the
TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.
That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.
Now sched_mm_cid_exit() assumes that the CID is CPU owned because the
prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the
not set ONCPU bit and then invokes clear_bit() with an insanely large
bit number because TRANSIT is set (bit 29).
Prevent that by actually validating that the CID is CPU owned in
mm_drop_cid_on_cpu().
Fixes:

sound updates for 7.0-rc1
It's been relatively calm for a new era; majority of changes are for
ASoC, mostly device-specific changes, while there are a bit of
cleanups in core stuff. A few SPI API and regmap updates are included
to be used by sound drivers, too.
Core:
- A few trivial cleanups about __free() and runtime PM macros
- Convert to new snd_seq_bus binding
ASoC:
- Generic SDCA support for reporting jack events
- Continuing platform support, cleanup and feature improvements for
AMD, Intel, Qualcomm and SOF code
- Platform description improvements for the Cirrus drivers
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B
HD- and USB-audio:
- Many quirks as usual

firewire updates for v7.0
This update includes the following changes.
- Refactor page allocation dedicated to 1394 OHCI IR/IT/AR DMA contexts
Although 1394 OHCI specification does not impose any restriction on
the memory size dedicated to these DMA contexts, 1394 OHCI PCI driver
allocates pages for convenience when mapping them into either kernel
space or userspace VMA. The driver previously used dma_alloc_pages()
for both page allocation and mapping creation, even though this kernel
API is rarely used. Following discussions questioning the page-oriented
kernel API in the DMA layer, the driver has been refactored to avoid
using this API. In addition, the use of private members in the
allocated pages has been removed following long-standing concern.
- Allocate variable-sized buffer for isochronous context header
1394 OHCI PCI driver previously allocated a single page for isochronous
context header. As a result, the buffer size for the header was fixed
to PAGE_SIZE, which imposed a limitation on IEC 61883-1/6 packet
streaming engine. Consequently, the ALSA PCM devices provided by
drivers for audio and music units in IEEE 1394 bus were constrained in
the maximum size of buffer period (64 ms in most cases). This limitation
is resolved by dynamically allocating the header buffer with an
arbitrary size.

header was fixed to PAGE_SIZE, which imposed a limitation on IEC
61883-1/6 packet streaming engine. Consequently, the ALSA PCM devices
provided by drivers for audio and music units in IEEE 1394 bus were
constrained in the maximum size of buffer period (64 ms in most
cases). This limitation is resolved by dynamically allocating the
header buffer with an arbitrary size.
* tag 'firewire-updates-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394:
ALSA: firewire: remove PCM buffer size constraint from isoc context header
firewire: core: add fw_iso_context_create() variant with header storage size
firewire: core: provide isoc header buffer size outside card driver
firewire: ohci: allocate isoc context header by kvmalloc()
firewire: core: add flags member for isochronous context structure
firewire: ohci: use cleanup helper for isoc context header allocation
firewire: ohci: code refactoring to use union for isoc multiple channel state
firewire: ohci: refactor isoc single-channel state using a union
firewire: core: add function variants for isochronous context creation
firewire: ohci: fix index of pages for dma address to 1394 OHCI IT context
firewire: ohci: stop using page private to store DMA mapping address
firewire: ohci: split page allocation from dma mapping
firewire: ohci: use MAX macro to guarantee minimum count of pages for AR contexts
firewire: core: stop using page private to store DMA mapping address
firewire: core: use common kernel API to allocate and release a batch of pages
firewire: core: code refactoring with cleanup function for isoc pages
firewire: core: use mutex instead of spinlock for client isochronous context
firewire: core: move private function declaration from public header to internal header

spi: Updates for v7.0
The highlight here is that David Lechner has added support for multi-lane
SPI devices. Unlike the existing dual/quad SPI support this is for
devices (typically ADCs/DACs) which support multiple independent data
streams over multiple data lanes, instead of sending one data stream N
times as fast they simultaneously transfer N different data streams.
This is very similar to the case where multiple devices are grouped
together but in this case it's a single device in a way that's visible
to software.
Otherwise there's been quite a bit of work on existing drivers, both
cleanup and feature improvement, and a reasonable collection of new
drivers.
- Support for multi-lane SPI devices.
- Preparatory work for some memory mapped flash improvements that will
happen in the MTD subsystem.
- Several conversions to fwnode APIs.
- A bunch of cleanup and hardening work on the ST drivers.
- Support for DMA mode on Renesas RZV2H and i.MX target mode.
- Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1.

multi-lane SPI devices. Unlike the existing dual/quad SPI support this
is for devices (typically ADCs/DACs) which support multiple
independent data streams over multiple data lanes, instead of sending
one data stream N times as fast they simultaneously transfer N
different data streams.
This is very similar to the case where multiple devices are grouped
together but in this case it's a single device in a way that's visible
to software.
Otherwise there's been quite a bit of work on existing drivers, both
cleanup and feature improvement, and a reasonable collection of new
drivers.
- Support for multi-lane SPI devices
- Preparatory work for some memory mapped flash improvements that
will happen in the MTD subsystem
- Several conversions to fwnode APIs
- A bunch of cleanup and hardening work on the ST drivers
- Support for DMA mode on Renesas RZV2H and i.MX target mode
- Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1"

regulator: Updates for v7.0
There's a bunch of new drivers here, plus a lot of hardening for the
supply resolution code which allow us to support systems where we have
two PMICs each of which has regulators supplied by the other. This did
work a long time ago but got broken as part of improved integration with
the device model, it's fairly rare so nobody noticed.
- Improvements for supply handling from André Draszik to allow systems
with two PMICs with supply/consumer relationships in both
directions to instantiate.
- New drivers for Maxim MAX776750, Realtek RT8902, Samsung S2MPG11,
Texas Instuments TPS65185.
This have also pulls in some MFD updates which are build dependencies
for the Samsung S2MPG11 support.

soc: devicetree updates for 7.0
There are a handful of new SoCs this time, all of these are
more or less related to chips in a wider family:
- SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first
widely available RVA23 implementation. Note that this is
entirely unrelated with the similarly named Texas Instruments
K3 chip family that follwed the TI Keystone2 SoC.
- The Realtek Kent family of SoCs contains three chip models
rtd1501s, rtd1861b and rtd1920s, and is related to their earlier
Set-top-box and NAS products such as rtd1619, but is built
on newer Arm Cortex-A78 cores.
- The Qualcomm Milos family includes the Snapdragon 7s Gen 3
(SM7635) mobile phone SoC built around Armv9 Kryo cores of the Arm
Cortex-A720 generation. This one is used in the Fairphone Gen 6
- Qualcomm Kaanapali is a new SoC based around eight high
performance Oryon CPU cores
- NXP i.MX8QP and i.MX952 are both feature reduced versions of
chips we already support, i.e. the i.MX8QM and i.MX952, with
fewer CPU cores and I/O interfaces.
As part of a cleanup, a number of SoC specific devicetree files got
removed because they did not have a single board using the .dtsi files
and they were never compile tested as a result: Samsung s3c6400,
ST spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas
r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/
r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI am3703/am3715.
All of these could be restored easily if a new board gets merged.
Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
machine, as all remaining users are assumed to be using ACPI
based firmware.
A relatively small number of 43 boards get added this time, and
almost all of them for arm64. Aside from the reference boards for
the newly added SoCs, this includes:
- Three server boards use 32-bit ASpeed BMCs
- One more reference board for 32-bit Microchip LAN9668
- 64-bit Arm single-board computers based on Amlogic s905y4,
CIX sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95,
Qualcomm qcs6490/qrb2210 and Rockchip rk3568/rk3588s
- Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588
- Two mobile phones using Snapdragon 845
- A gaming device and a NAS box, both based on Rockchips rk356x
On top of the newly added boards and SoCs, there is a lot of
background activity going into cleanups, in particular towards
getting a warning-free dtc build, and the usual work on adding
support for more hardware on the previously added machines.

soc: driver updates for 7.0
There are are a number of to firmware drivers, in particular the TEE
subsystem:
- a bus callback for TEE firmware that device drivers can register to
- sysfs support for tee firmware information
- minor updates to platform specific TEE drivers for AMD, NXP, Qualcomm
and the generic optee driver
- ARM SCMI firmware refactoring to improve the protocol discover
among other fixes and cleanups
- ARM FF-A firmware interoperability improvements
The reset controller and memory controller subsystems gain support for
additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
SpacemiT.
Most of the other changes are for random drivers/soc code. Among
a number of cleanups and newly added hardware support, including:
- Mediatek MT8196 DVFS power management and mailbox support
- Qualcomm SCM firmware and MDT loader refactoring, as part of
the new Glymur platform support.
- NXP i.MX9 System Manager firmware support for accessing the
syslog
- Minor updates for TI, Renesas, Samsung, Apple, Marvell and AMD
SoCs.

asm-generic header updates for 7.0
A series from Thomas Weißschuh cleans up the UAPI header files to no longer contain any references to Kconfig symbols, as these make no sense in userspace. The build-time check for these was originally added by Sam Ravnborg in linux-2.6.28, and a later version started warning for all newly added CONFIG_* checks here but kept a list of known exceptions. With the last exceptions gone from that list, the warning is now unconditional in 'make headers_install'.

Updates for the VDSO subsystem:
- Provide the missing 64-bit variant of clock_getres()
This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
finally the removal of 32-bit time types from the kernel and UAPI.
- Remove the useless and broken getcpu_cache from the VDSO
The intention was to provide a trivial way to retrieve the CPU number from
the VDSO, but as the VDSO data is per process there is no way to make it
work.
- Switch get/put_unaligned() from packed struct to memcpy()
The packed struct violates strict aliasing rules which requires to pass
-fno-strict-aliasing to the compiler. As this are scalar values
__builtin_memcpy() turns them into simple loads and stores
- Use __typeof_unqual__() for __unqual_scalar_typeof()
The get/put_unaligned() changes triggered a new sparse warning when __beNN
types are used with get/put_unaligned() as sparse builds add a special
'bitwise' attribute to them which prevents sparse to evaluate the Generic
in __unqual_scalar_typeof().
Newer sparse versions support __typeof_unqual__() which avoids the problem,
but requires a recent sparse install. So this adds a sanity check to sparse
builds, which validates that sparse is available and capable of handling it.
- Force inline __cvdso_clock_getres_common()
Compilers sometimes un-inline agressively, which results in function call
overhead and problems with automatic stack variable initialization.
Interestingly enough the force inlining results in smaller code than the
un-inlined variant produced by GCC when optimizing for size.

Pull VDSO updates from Thomas Gleixner:
- Provide the missing 64-bit variant of clock_getres()
This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
finally the removal of 32-bit time types from the kernel and UAPI.
- Remove the useless and broken getcpu_cache from the VDSO
The intention was to provide a trivial way to retrieve the CPU number
from the VDSO, but as the VDSO data is per process there is no way to
make it work.
- Switch get/put_unaligned() from packed struct to memcpy()
The packed struct violates strict aliasing rules which requires to
pass -fno-strict-aliasing to the compiler. As this are scalar values
__builtin_memcpy() turns them into simple loads and stores
- Use __typeof_unqual__() for __unqual_scalar_typeof()
The get/put_unaligned() changes triggered a new sparse warning when
__beNN types are used with get/put_unaligned() as sparse builds add a
special 'bitwise' attribute to them which prevents sparse to evaluate
the Generic in __unqual_scalar_typeof().
Newer sparse versions support __typeof_unqual__() which avoids the
problem, but requires a recent sparse install. So this adds a sanity
check to sparse builds, which validates that sparse is available and
capable of handling it.
- Force inline __cvdso_clock_getres_common()
Compilers sometimes un-inline agressively, which results in function
call overhead and problems with automatic stack variable
initialization.
Interestingly enough the force inlining results in smaller code than
the un-inlined variant produced by GCC when optimizing for size.

Updates for the core time subsystem:
- Inline timecounter_cyc2time() as that is now used in the networking
hotpath. Inlining it significantly improves performance.
- Optimize the tick dependency check in case that the tracepoint is disabled,
which improves the hotpath performance in the tick management code, which
is a hotpath on transitions in and out of idle.
- The usual cleanups and improvements

Updates for the [PCI] MSI subsystem:
- Add interrupt redirection infrastructure
Some PCI controllers use a single demultiplexing interrupt for the MSI
interrupts of subordinate devices.
This prevents setting the interrupt affinity of device interrupts, which
causes device interrupts to be delivered to a single CPU. That obviously is
counterproductive for multi-queue devices and interrupt balancing.
To work around this limitation the new infrastructure installs a dummy
irq_set_affinity() callback which captures the affinity mask and picks a
redirection target CPU out of the mask.
When the PCI controller demultiplexes the interrupts it invokes a new
handling function in the core, which either runs the interrupt handler in
the context of the target CPU or delegates it to irq_work on the target CPU.
- Utilize the interrupt redirection mechanism in the PCI DWC host controller
driver.
This allows affinity control for the subordinate device MSI interrupts
instead of being randomly executed on the CPU which runs the demultiplex
handler.
- Replace the binary 64-bit MSI flag with a DMA mask
Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but
implement less than 64 address bits. This breaks on platforms where such a
device is assigned an MSI address higher than what's supported.
With the binary 64-bit flag there is no other choice than disabling 64-bit
MSI support which leaves the device disfunctional.
By using a DMA mask the address limit of a device can be described
correctly which provides support for the above scenario.
- Make use of the DMA mask based address limit in the hda/intel and radeon
drivers to enable them on affected platforms.
- The usual small cleanups and improvements

Updates for interrupt chip drivers:
- Add support for the Renesas RZ/V2N SoC
- Add a new driver for the Renesas RZ/[TN]2H SoCs
- Preserve the register state of the RISCV APLIC interrupt controller accross
suspend/resume
- Reinitialize the RISCV IMSIC registers after suspend/resume
- Make the various Loongson interrupt chip drivers 32/64-bit aware
- Handle the number of hardware interrupts in the SIFIVE PLIC driver
correctly.
The hardware interrupt 0 is reserved which resulted in inconsistent
accounting. That went unnoticed as the off by one is only noticable when
the number of device interrupts is a multiple of 32.
- The usual device tree updates, cleanups and improvements all over the place.
