RISC-V updates for v6.18-rc2

Some RISC-V fixes for v6.18-rc2, including changes to:

- Disable CFI with Rust for any platform other than x86 and ARM64

- Keep task mm_cpumasks up-to-date to avoid triggering M-mode firmware
  warnings if the kernel tries to send an IPI to an offline CPU

- Improve kprobe address validation performance and avoid desyncs
  (following x86)

- Avoid duplicate device probes by avoiding DT hardware probing when
  ACPI is enabled in early boot

- Use the correct set of dependencies for CONFIG_ARCH_HAS_ELF_CORE_EFLAGS,
  avoiding an allnoconfig warning

- Fix a few other minor issues
