#     Merge tag 'perf-tools-fixes-for-v5.18-2022-04-09' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Fix the clang command line option probing and remove some options to
#        filter out, fixing the build with the latest clang versions
#     
#      - Fix 'perf bench' futex and epoll benchmarks to deal with machines
#        with more than 1K CPUs
#     
#      - Fix 'perf test tsc' error message when not supported
#     
#      - Remap perf ring buffer if there is no space for event, fixing perf
#        usage in 32-bit ChromeOS
#     
#      - Drop objdump stderr to avoid getting stuck waiting for stdout output
#        in 'perf annotate'
#     
#      - Fix up garbled output by now showing unwind error messages when
#        augmenting frame in best effort mode
#     
#      - Fix perf's libperf_print callback, use the va_args eprintf() variant
#     
#      - Sync vhost and arm64 cputype headers with the kernel sources
#     
#      - Fix 'perf report --mem-mode' with ARM SPE
#     
#      - Add missing external commands ('iiostat', etc) to 'perf --list-cmds'
#
