#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#      "Vendor events:
#     
#        - Intel Alderlake/Sapphire Rapids metric fixes, the CPU type
#          ("cpu_atom", "cpu_core") needs to be used as a prefix to be
#          considered on a metric formula, detected via one of the 'perf test'
#          entries.
#     
#       'perf test' fixes:
#     
#        - Fix the creation of event selector lists on 'perf test' entries, by
#          initializing the sample ID flag, which is done by 'perf record', so
#          this fix affects only the tests, the common case isn't affected
#     
#        - Make 'perf list' respect debug settings (-v) to fix its 'perf test'
#          entry
#     
#        - Fix 'perf script' test when python support isn't enabled
#     
#        - Special case 'perf script' tests on s390, where only DWARF call
#          graphs are supported and only on software events
#     
#        - Make 'perf daemon' signal test less racy
#     
#       Compiler warnings/errors:
#     
#        - Remove needless malloc(0) call in 'perf top' that triggers
#          -Walloc-size
#     
#        - Fix calloc() argument order to address error introduced in gcc-14
#     
#       Build:
#     
#        - Make minimal shellcheck version to v0.6.0, avoiding the build to
#          fail with older versions
#     
#       Sync kernel header copies:
#     
#        - stat.h to pick STATX_MNT_ID_UNIQUE
#     
#        - msr-index.h to pick IA32_MKTME_KEYID_PARTITIONING
#     
#        - drm.h to pick DRM_IOCTL_MODE_CLOSEFB
#     
#        - unistd.h to pick {list,stat}mount,
#          lsm_{[gs]et_self_attr,list_modules} syscall numbers
#     
#        - x86 cpufeatures to pick TDX, Zen, APIC MSR fence changes
#     
#        - x86's mem{cpy,set}_64.S used in 'perf bench'
#     
#        - Also, without tooling effects: asm-generic/unaligned.h, mount.h,
#          fcntl.h, kvm headers"
