Re: nptl 0.41

[Steven Munroe <sjmunroe us ibm com>]

Is nptl 0.41 still "considered more or less x86-only." like nptl-0.40 or 
is it intended for general use?

PPC (and I suspect S390 and SH) is broken due to the futex requeue 
change.  kernel-features.h has __ASSUME_FUTEX_REQUEUE but that is not 
used in the common ./libc23/nptl/sysdeps/pthread/pthread_cond_*.c 
source. It seems pthread_cond_wait.c, pthread_cond_signal.c, and 
pthread_cond_broadcast.c  where changed to use __data.__mutex and 
lll_futex_requeue without conditioning it on __ASSUME_FUTEX_REQUEUE.

What is the general intent for this;
1) all platforms should assume the new kernel and ignore 
__ASSUME_FUTEX_REQUEUE,
2) or nptl should honor __ASSUME_FUTEX_REQUEUE and continue to support 
pre 2.5.70 kernels?
