[PATCH 0/3] x86: Provide a vdso for getcpu on x86-32.

[Sebastian Andrzej Siewior]

This tiny series provides getcpu in vdso on x86-32. Due to the setup
RDTSCP now also returns CPU and node information like x86-64 does.

The usage of RDTSCP + vdso has been tested in a VM with 64bit kernel and
32bit binary and a 32bit kernel.
