Fixes boot failures on 6.9 on PPC_BOOK3S_32 machines using Open Firmware.
On these machines, the kernel refuses to boot from non-zero
PHYSICAL_START, which occurs when CRASH_DUMP is on.
Since most PPC_BOOK3S_32 machines boot via Open Firmware, it should
default to off for them. Users booting via some other mechanism can still
turn it on explicitly.
Does not change the default on any other architectures for the
time being.

For ARM's implementation, perf_instruction_pointer() and
perf_misc_flags() are equivalent to the generic versions in
include/linux/perf_event.h so arch/arm doesn't need to provide its
own versions. Drop them here.

The code for syncing vmalloc memory PGD pointers is using
atomic_read() in pair with atomic_set_release() but the
proper pairing is atomic_read_acquire() paired with
atomic_set_release().
This is done to clearly instruct the compiler to not
reorder the memcpy() or similar calls inside the section
so that we do not observe changes to init_mm. memcpy()
calls should be identified by the compiler as having
unpredictable side effects, but let's try to be on the
safe side.

When sync:ing the VMALLOC area to other CPUs, make sure to also
sync the KASAN shadow memory for the VMALLOC area, so that we
don't get stale entries for the shadow memory in the top level PGD.
Since we are now copying PGDs in two instances, create a helper
function named memcpy_pgd() to do the actual copying, and
create a helper to map the addresses of VMALLOC_START and
VMALLOC_END into the corresponding shadow memory.

When enabling expert mode CONFIG_EXPERT and using that power
user mode to disable the branch prediction hardening
!CONFIG_HARDEN_BRANCH_PREDICTOR, the assembly linker
in CLANG notices that some assembly in proc-v7.S does
not have corresponding C call sites, i.e. the prototypes
in proc-v7-bugs.c are enclosed in ifdef
CONFIG_HARDEN_BRANCH_PREDICTOR so this assembly:
SYM_TYPED_FUNC_START(cpu_v7_smc_switch_mm)
SYM_TYPED_FUNC_START(cpu_v7_hvc_switch_mm)
Results in:
ld.lld: error: undefined symbol: __kcfi_typeid_cpu_v7_smc_switch_mm
>>> referenced by proc-v7.S:94 (.../arch/arm/mm/proc-v7.S:94)

>>> arch/arm/mm/proc-v7.o:(.text+0x124) in archive vmlinux.a
Fix this by adding an additional requirement that
CONFIG_HARDEN_BRANCH_PREDICTOR has to be enabled to compile
these assembly calls.

Qualcomm Arm64 DeviceTree changes for v6.13
Introduce descriptions of the 8cx Gen3-based Microsoft Surface Pro 9 5G,
X Elite based Dell XPS 13 9345, the QCS9100 platform and the "Ride"
development boards thereon, and the SM7325 platform and the Nothing
Phone 1.
MSM8998 gains support for HDMI. The Lenovo Miix 630 gains support for
volume keys, audio and sensor DSPs, touchscreen, and its specific WiFi
calibration variant.
On QCM6490, Fairphone FP5 gains a thermistor adjacent to UFS/RAM, while
the IDP gains UFS and WiFi support. For QCS6490 changes to Rb3Gen2
enables WiFi, Venus, PCIe, SD-card, and volume keys. Adreno speedbins
are adjusted and PMU nodes' compatibles for the two clusters are
corrected.
The DB845C/RB3 and QRB5165 RB5 vision mezzanines are converted to
DeviceTree overlays, and both gains CMA heap for libcamera to use.
SA8775P gains GPI DMA support, support for controlling download mode
(bootloader-assisted ramdump support), additional UARTs, and qcrypto
support. The "Ride" development board gains WiFi and Bluetooth support.
On SC8280XP (8cx Gen3) another UART is described, used in the
Microsoft Surface 9 5G. The WiFi/BT combo chip's power management unit
is described on the CRD and Lenovo ThinkPad X13s.
On SDM630/660 the GPU SMMU and clock controller is added, as is the
A2Noc and LPASS SMMU, and the DSP-based WiFi device. GPU, modem DSP and
WiFi is then enabled on the Inforce 6560 development board.
On SM8450 Hardware Development Kit, the WCN6855 is modelled to enable
WiFi and Bluetooth. A "global" interrupt is defined on SM8450 PCIe RC
controller, to enable hotplug.
On X Elite, USB Type-C controllers are marked as usb-role-switch
capable, the GICv3 ITS is enabled for PCIe. TCSR region is described and
wired up to allow setting and cleaning the download mode
(bootloader-assisted ramdump) flag, and residency numbers for C4/C5 are
updated.
USB role switch is enabled on Lenovo ThinkPad T14s and the ASUS Vivobook
S15. The T14s also gains support for a second source trackpad. The
Microsoft Surface Laptop gains LID switch and the USB Type-A connector
attached to the multiport controller is enabled. The CRD has its HID
device power supplies described.
Application SMMU is flagged as DMA coherent across QDU1000, SC7180,
SC8180X, SC8280XP, SDM670, SDM845, SM8150, SM8350, SM8450, and X1E80100.
In addition to this, the effort to improve style and binding compliance
continued.

VFP_bounce() is invoked from within vfp_support_entry() and may send a
signal. Sending a signal uses spinlock_t which becomes a sleeping lock
on PREEMPT_RT and must not be acquired within a preempt-disabled
section.

vfp_entry() is invoked from exception handler and is fully preemptible.
It uses local_bh_disable() to remain uninterrupted while checking the
VFP state.
This is not working on PREEMPT_RT because local_bh_disable()
synchronizes the relevant section but the context remains fully
preemptible.
Use vfp_state_hold() for uninterrupted access.

vfp_sync_hwstate() uses preempt_disable() followed by local_bh_disable()
to ensure that it won't get interrupted while checking the VFP state.
This harms PREEMPT_RT because softirq handling can get preempted and
local_bh_disable() synchronizes the related section with a sleeping lock
which does not work with disabled preemption.
Use the vfp_state_hold() to synchronize the access.

kernel_neon_begin() uses local_bh_disable() to ensure exclusive access
to the VFP unit. This is broken on PREEMPT_RT because a BH disabled
section remains preemptible on PREEMPT_RT.
Introduce vfp_state_hold() which uses local_bh_disable() and
preempt_disable() on PREEMPT_RT. Since softirqs are processed always in
thread context, disabling preemption is enough to ensure that the
current context won't get interrupted by something that is using the
VFP. Use it in kernel_neon_begin().

The patchset introducing kernel_sec_start/end variables to separate the
kernel/lowmem memory mappings, broke the mapping of the kernel memory
for xipkernels.
kernel_sec_start/end variables are in RO area before the MMU is switched
on for xipkernels.
So these cannot be set early in boot in head.S. Fix this by setting these
after MMU is switched on.
xipkernels need two different mappings for kernel text (starting at
CONFIG_XIP_PHYS_ADDR) and data (starting at CONFIG_PHYS_OFFSET).
Also, move the kernel code mapping from devicemaps_init() to map_kernel().

Add the four syscalls setxattrat(), getxattrat(), listxattrat() and
removexattrat(). Those can be used to operate on extended attributes,
especially security related ones, either relative to a pinned directory
or on a file descriptor without read access, avoiding a
/proc/<pid>/fd/<fd> detour, requiring a mounted procfs.
One use case will be setfiles(8) setting SELinux file contexts
("security.selinux") without race conditions and without a file
descriptor opened with read access requiring SELinux read permission.
Use the do_{name}at() pattern from fs/open.c.
Pass the value of the extended attribute, its length, and for
setxattrat(2) the command (XATTR_CREATE or XATTR_REPLACE) via an added
struct xattr_args to not exceed six syscall arguments and not
merging the AT_* and XATTR_* flags.
[AV: fixes by Christian Brauner folded in, the entire thing rebased on
top of {filename,file}_...xattr() primitives, treatment of empty
pathnames regularized. As the result, AT_EMPTY_PATH+NULL handling
is cheap, so f...(2) can use it]

In do_adjust_pte(), we may modify the pte entry. The corresponding pmd
entry may have been modified concurrently. Therefore, in order to ensure
the stability if pmd entry, use pte_offset_map_rw_nolock() to replace
pte_offset_map_nolock(), and do pmd_same() check after holding the PTL.
All callers of update_mmu_cache_range() hold the vmf->ptl, so we can
determined whether split PTE locks is being used by doing the following,
just as we do elsewhere in the kernel.
ptl != vmf->ptl
And then we can delete the do_pte_lock() and do_pte_unlock().

To avoid duplication of inline asm between C and Rust, we need to
import the inline asm from the relevant `jump_label.h` header into Rust.
To make that easier, this patch updates the header files to expose the
inline asm via a new ARCH_STATIC_BRANCH_ASM macro.
The header files are all updated to define a ARCH_STATIC_BRANCH_ASM that
takes the same arguments in a consistent order so that Rust can use the
same logic for every architecture.

Commit b9bf5612610aa7e3 ("ARM: dts: am335x-bone-common: Increase MDIO
reset deassert time") already increased the MDIO reset deassert delay
from 6.5 to 13 ms, but this may still cause Ethernet PHY probe failures:
SMSC LAN8710/LAN8720 4a101000.mdio:00: probe with driver SMSC LAN8710/LAN8720 failed with error -5
On BeagleBone Black Rev. C3, ETH_RESETn is controlled by an open-drain
AND gate. It is pulled high by a 10K resistor, and has a 4.7µF
capacitor to ground, giving an RC time constant of 47ms. As it takes
0.7RC to charge the capacitor above the threshold voltage of a CMOS
input (VDD/2), the delay should be at least 33ms. Considering the
typical tolerance of 20% on capacitors, 40ms would be safer. Add an
additional safety margin and settle for 50ms.

Adds a devicetree for the Kobo Clara 2E Ebook reader. It is based
on boards marked with "37NB-E60K2M+4A2" or "37NB-E60K2M+4B0". It is
equipped with an i.MX6SLL SoC.
Expected to work:
- Buttons
- Wifi
- Bluetooth
(if Wifi is initialized first, driver does not handle regulators
yet)
- LED
- uSD
- USB
- RTC
- Touchscreen
Add human-readable comments for devices without mainlined driver and
binding. Such comments can e.g. be help to find testers if someone
starts to work on the missing drivers.
