Thank you for the report!
I confirmed about could not get CPUInfo on ARM v7, ubuntu 15.04 by using https://www.scaleway.com/.
I prefer more widely used way. I think your a) lscpu approach is major than b). I would appreciate you if you make some PR. Thank you.

@shirou awesome. i would love to contribute :-)
Question: lscpu output is fairly different than /proc/cpuinfo ,
- it does not have things like flags, cpu family etc.
- fields are inconsistent across arch. I'm posting examples of intel and arm
lscpudata. e.g. CPU MHz has min & max fields on arm - lscpu data is aggregate output. i.e. unlike cpuinfo which has one entry per core, lscpu is summary of all cpu
- fields are inconsistent across arch. I'm posting examples of intel and arm
I am thinking of several things, but not sure which one is best.
- introduce a separate struct to expose lscpu info (consumer codes need to be updated)
- interpret and build a array of CPUStats from lscpu data (not sure we'll get all logic right, or we;ll have all data.)
comments?

@ranjib Thank you for the information. On my understanding, only ARM can not get information from /proc/cpuinfo. So I think how about separating into two files cpu_linux.go and cpu_linux_arm.go such as
- for amd, get from
/proc/cpuinfo - for ARM, get from
lscpu
Will that work?

@shirou That sounds good to me! I am not familiar with arm on linux outside of Rasbpian but that's my primary use case for this feature. Let me know if you need help with this.
