Pull arm64 updates from Catalin Marinas:
"The major features are support for LPA2 (52-bit VA/PA with 4K and 16K
pages), the dpISA extension and Rust enabled on arm64. The changes are
mostly contained within the usual arch/arm64/, drivers/perf, the arm64
Documentation and kselftests. The exception is the Rust support which
touches some generic build files.
Summary:
- Reorganise the arm64 kernel VA space and add support for LPA2 (at
stage 1, KVM stage 2 was merged earlier) - 52-bit VA/PA address
range with 4KB and 16KB pages
- Enable Rust on arm64
- Support for the 2023 dpISA extensions (data processing ISA), host
only
- arm64 perf updates:
- StarFive's StarLink (integrates one or more CPU cores with a
shared L3 memory system) PMU support
- Enable HiSilicon Erratum 162700402 quirk for HIP09
- Several updates for the HiSilicon PCIe PMU driver
- Arm CoreSight PMU support
- Convert all drivers under drivers/perf/ to use .remove_new()
- Miscellaneous:
- Don't enable workarounds for "rare" errata by default
- Clean up the DAIF flags handling for EL0 returns (in preparation
for NMI support)
- Kselftest update for ptrace()
- Update some of the sysreg field definitions
- Slight improvement in the code generation for inline asm I/O
accessors to permit offset addressing
- kretprobes: acquire regs via a BRK exception (previously done
via a trampoline handler)
- SVE/SME cleanups, comment updates
- Allow CALL_OPS+CC_OPTIMIZE_FOR_SIZE with clang (previously
disabled due to gcc silently ignoring -falign-functions=N)"

We typically enable support in defconfig for all architectural features
for which we can detect at runtime if the hardware actually supports
them.
Now that we have implemented support for LPA2 based 52-bit virtual
addressing in a way that should not impact 48-bit operation on non-LPA2
CPU, we can do the same, and enable 52-bit virtual addressing by
default.
Catalin adds:
Currently the "Virtual address space size" arch/arm64/Kconfig menu
entry sets different defaults for each page size. However, all are
overridden by the defconfig to 48 bits. Set the new default in
Kconfig and remove the defconfig line.

With interconnect providers built as modules Qualcomm SM8250 and QCM2290
platforms launches init without /dev/console being backed by the debug
UART.
Build there drivers into the kernel, to make sure the dependencies for
the UART driver are available and thereby give userspace access to the
UART without having to re-open the console, once the deferred UART
driver has probed.

Enable global clock controller and pinctrl for support the Qualcomm
SM4450 platform to boot to UART console.
The serial engine depends on some global clock controller and pinctrl, but
as the serial console driver is only available as built-in, so the global
clock controller and pinctrl also needs be built-in for the UART device to
probe and register the console.

Increase CONFIG_SERIAL_8250_NR_UARTS from 4 to 8, the current legacy value
is not adequate for embedded systems that use SoCs where it's common to
have a large number of serial ports.
No need to change CONFIG_SERIAL_8250_RUNTIME_UARTS, see commit 9d86719f87
("serial: 8250: Allow using ports higher than SERIAL_8250_RUNTIME_UARTS").
The need to increase this value was noticed while working with Toradex
Verdin AM62, this board has 4 serial UART instances available to the user
plus an internal one that is connected to a Bluetooth module. Without this
change the fifth UART connected to the BT module is not instantiated and BT
is not working.
Instead of increasing the number to the bare minimum (5) that would be
required to solve this specific issue, we increase this to 8 which seems a
more reasonable number to have in the defconfig and should cover more valid
use cases.
With this change the kernel image size increases by ~3.2kB. bloat-o-meter
