VM.info / hs_err logs should include the exact CPU model. Solaris seems to be the only supported platform where this is not provided.

For example, output similar to what "psrinfo -pv" produces would be very helpful.

We already have code in HotSpot that collects this information via kstat (see vm_version_ext_sparc.cpp). Currently, this code looks like it is only utilized by JFR. Hopefully it will not be too much effort to always call this on startup (regardless of JFR usage) and include the resulting CPU info into VM.info / hs_err output.
