Hi,

__cpu_name[] will be displayed as "cpu model" in cpuinfo, however
in x86 world, the name line is started with "model name"=2E
Most user applications like lscpu, hwinfo is following x86's rule, we don'=
t have superpower to move all of them=2E

Also rename "cpu model" will break current ABI, so just create a new array
for it would be a better option=2E

For why Loongson is doing this, I guess they need a chance to show
their business processor name instead of revision=2E

Thanks
