[PATCH 3/3] perf: Fix unaligned accesses while fetching trace values
Accessing trace values of an 8 size may end up in a segfault on archs that can't deal with misaligned access, which is the case for sparc 64. This is because PERF_SAMPLE_RAW are aligned to 4 and not to 8. Fix this on the macros that get the values of 8 size. This fixes segfaults on perf tools in sparc 64. S... 20 May 2010 06:13
