On linux only, we print /proc/cpuinfo into the hs_err files which can be really long and redundant information for each processor and especially annoying when we have a lot of processors. We already print this:

CPU:total 4 (4 cores per cpu, 1 threads per core) family 6 model 58 stepping 9, cmov, cx8, fxsr, mmx, sse, sse2, sse3, ssse3, sse4.1, sse4.2, popcnt, avx, aes, clmul, erms, tsc, tscinvbit, tscinv

Not sure why we need the /proc/cpuinfo printed out. I don't know if anyone would ever use this specific (redundant) information to diagnose a problem.

os_aix.cpp has pd_print_cpu_info() which is called from os::print_cpu_info() which prints the exact same thing and should be removed.

It looks like this code was separated out of some other code that added this printing.
