Merge tag 'perf-tools-for-v6.18-1-2025-10-08' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Arnaldo Carvalho de Melo:

 - Extended 'perf annotate' with DWARF type information
   (--code-with-type) integration in the TUI, including a 'T'
   hotkey to toggle it

 - Enhanced 'perf bench mem' with new mmap() workloads and control
   over page/chunk sizes

 - Fix 'perf stat' error handling to correctly display unsupported
   events

 - Improved support for Clang cross-compilation

 - Refactored LLVM and Capstone disasm for modularity

 - Introduced the :X modifier to exclude an event from automatic
   regrouping

 - Adjusted KVM sampling defaults to use the "cycles" event to prevent
   failures

 - Added comprehensive support for decoding PowerPC Dispatch Trace Log
   (DTL)

 - Updated Arm SPE tracing logic for better analysis of memory and snoop
   details

 - Synchronized Intel PMU events and metrics with TMA 5.1 across
   multiple processor generations

 - Converted dependencies like libperl and libtracefs to be opt-in

 - Handle more Rust symbols in kallsyms ('N', debugging)

 - Improve the python binding to allow for python based tools to use
   more of the libraries, add a 'ilist' utility to test those new
   bindings

 - Various 'perf test' fixes

 - Kan Liang no longer a perf tools reviewer
