Removed restriction of displaying model name for 32 bit tasks only.
This can be used for 64 bit tasks as well, and it's useful for some
tools that already parse this, such as coreutils `uname -p`, Ubuntu
model name display etc.
How exactly is it useful? It clearly isn't necessary for compatibility,
since AArch64 userspace has apparently been running quite happily for 8
years without it. It also doesn't convey anything meaningful to the
user, since they already know they're on an Armv8-compatible processor
by the fact that they're running AArch64 userspace at all.
Robin.
It should be like this:
```
$ cat '/proc/cpuinfo' | grep 'model name' | head -n 1
model name : ARMv8 Processor rev X (v8l)
```
