Subject: [GIT PULL] arm64 updates for 6.2
Hi Linus,
Please pull these arm64 updates for the 6.2 merge window.
There's the usual summary in the tag, with the highlights this time being
support for dynamically enabling/disabling Clang's Shadow Call Stack at
boot and a long-awaited optimisation to the way in which we handle the
SVE register state on system call entry to avoid taking unnecessary traps
from userspace.
A few small things to note:
* for-next/sysregs is shared with the KVM tree, since it conflicts
with some rework of the PMU handling code in the hypervisor.
* We have some refactoring changes to the core ftrace code reworking
FTRACE_WITH_REGS and fixing up PowerPC, S390 and x86 (acked by Steve
and Masami). We build on top of this to enable FTRACE_WITH_ARGS on
arm64.
* We dropped for-next/uaccess fairly late in the cycle after Syzkaller
ran into an issue with the fault handling in copy_to_user(). Hopefully
we'll bring it back next time once we've got deterministic testing
coverage of all the exception fixups.
It's all been sitting happily in -next for a while now.
Cheers,
Will

Merge branch 'for-next/undef-traps' into for-next/core (2022-12-06 11:34:25 +0000)
----------------------------------------------------------------
arm64 updates for 6.2
ACPI:
* Enable FPDT support for boot-time profiling
* Fix CPU PMU probing to work better with PREEMPT_RT
* Update SMMUv3 MSI DeviceID parsing to latest IORT spec
* APMT support for probing Arm CoreSight PMU devices
CPU features:
* Advertise new SVE instructions (v2.1)
* Advertise range prefetch instruction
* Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
* Enable DIT (Data Independent Timing) when running in the kernel
* More conversion of system register fields over to the generated
header
CPU misfeatures:
* Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
* Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's
pointer authentication feature when it is supported (complete
with scary DWARF parser!)
Tracing and debug:
* Remove static ftrace in favour of, err, dynamic ftrace!
* Seperate 'struct ftrace_regs' from 'struct pt_regs' in core
ftrace and existing arch code
* Introduce and implement FTRACE_WITH_ARGS on arm64 to replace
the old FTRACE_WITH_REGS
* Extend 'crashkernel=' parameter with default value and fallback
to placement above 4G physical if initial (low) allocation
fails
SVE:
* Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
* Rework of undefined instruction handling to avoid serialisation
on global lock (this includes emulation of user accesses to the
ID registers)
Perf and PMU:
* Support for TLP filters in Hisilicon's PCIe PMU device
* Support for the DDR PMU present in Amlogic Meson G12 SoCs
* Support for the terribly-named "CoreSight PMU" architecture
from Arm (and Nvidia's implementation of said architecture)
Misc:
* Tighten up our boot protocol for systems with memory above
52 bits physical
* Const-ify static keys to satisty jump label asm constraints
* Trivial FFA driver cleanups in preparation for v1.1 support
* Export the kernel_neon_* APIs as GPL symbols
* Harden our instruction generation routines against
instrumentation
* A bunch of robustness improvements to our arch-specific selftests
* Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)
