Subject: [RELEASE] Userspace RCU 0.5.1

Well well, a renaming error seems to have crept into 0.5.0, which caused
problems with atomic operations on 64-bit architectures.

I made sure no other similar problem exist. Anyone using 0.5.0 (released a few
hours ago) should upgrade to 0.5.1.

Thank you,

Mathieu
