The following patch is part of a patch that was submitted by Hiroki Kaminaga to
libc-help on April 28, 2008.
Here's a summary of the analysis I performed upon his original patch which
excludes the necessity of adding tcbhead_t.private_futex in
nptl/sysdeps/powerpc/tls.h
http://sourceware.org/ml/libc-help/2008-07/msg00042.html
I've attached a ChangeLog.
