Eric W. Biederman ebiederm at xmission.com
Fri May 6 19:25:01 PDT 2011


v2: Most of the architecture support added by Daniel Lezcano <dlezcano at fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm at xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
