Subject: Re: futex_cmpxchg_enabled not set in futex_init on pentium3

Hello:

Just installed 2.6.32 and the problem is still there.  The value returned
for curval in futex_init is still the same 0xf0006aa0, and thus as before
futex_cmpxchg_enabled is not set, thus causing many kernel futex syscalls to
return -ENOSYS incorrectly, the proximate cause of the glibc test failures.

Regards,

Joseph
