Hi Sami,

Thanks for the reply. I include the output file from mk-input.sh, I have
to note that there were a three permission denied instances.

# sh tests/ts/lscpu/mk-input.sh vmware-esxi
cp: cannot open ‘/sys/devices/system/cpu/microcode/reload’ for reading:
Permission denied
cp: cannot open ‘/sys/devices/system/cpu/probe’ for reading: Permission
denied
cp: cannot open ‘/sys/devices/system/cpu/release’ for reading:
Permission denied

Feel free to use it as part of the regression test suite.
