Merge tag 'perf-tools-fixes-for-v6.18-1-2025-11-06' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Add James Clark as a perf tools reviewer

 - Handle '1' type symbols in /proc/kallsyms, related to anonymous
   Rust closures in the DRM panic QR encoder, caught by 'perf test'

 - Sync kernel header copies: MSRs, uprobe syscall,
   DRM_IOCTL_GEM_CHANGE_HANDLE, KVM exit reasons, etc
