parentperf tools: Fix probing for PERF_FLAG_FD_CLOEXEC flag (diff)
perf top: Fix SIGBUS on sparc64
perf-top is terminating due to SIGBUS on sparc64. git bisect points to: commit 82396986032915c1572bfb74b224fcc2e4e8ba7c Author: Arnaldo Carvalho de Melo <acme@redhat.com> Date: Mon Sep 8 13:26:35 2014 -0300 perf evlist: Refcount mmaps We need to know how many fds are using a perf mmap via PERF_EVENT_IOC_SET_OUTPUT, so that we can know when to ditch an mmap, refcount it. This commit added 'int refcnt' to struct perf_mmap and the addition makes the event_copy element no longer 8-byte aligned. Fix by adding __attribute__((aligned(8))) to the event_copy struct member.
