Fixes 32-bit ppc dumping 64-bit x86 feature data: ======== captured on: Sun May 20 19:23:23 2012 hostname : nxos-vdc-dev3 os release : 3.4.0-rc7+ perf version : 3.4.rc4.137.g978da3 arch : x86_64 nrcpus online : 16 nrcpus avail : 16 cpudesc : Intel(R) Xeon(R) CPU E5540 @ 2.53GHz cpuid : GenuineIntel,6,26,5 total memory : 24680324 kB ...
