#     Merge tag 'perf-tools-fixes-for-v5.12-2020-03-28' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull perf tooling fixes from Arnaldo Carvalho de Melo:
#     
#      - Avoid write of uninitialized memory when generating PERF_RECORD_MMAP*
#        records.
#     
#      - Fix 'perf top' BPF support related crash with perf_event_paranoid=3 +
#        kptr_restrict.
#     
#      - Validate raw event with sysfs exported format bits.
#     
#      - Fix waipid on SIGCHLD delivery bugs in 'perf daemon'.
#     
#      - Change to use bash for daemon test on Debian, where the default is
#        dash and thus fails for use of bashisms in this test.
#     
#      - Fix memory leak in vDSO found using ASAN.
#     
#      - Remove now useless (due to the fact that BPF now supports static
#        vars) failing sub test "BPF relocation checker".
#     
#      - Fix auxtrace queue conflict.
#     
#      - Sync linux/kvm.h with the kernel sources.
