Subject: PATCH: Add memory barrier to malloc

We got corrupted linked list in malloc due to memory ordering issues
on our ia64 MP machine. This URL

http://lse.sourceforge.net/locking/wmbdd.html

has some relevant info. We need to make memory barrier available
to the whole glibc, even user application source codes. This patch
adds memory-barrier.h to glibc internal headers and adds one memory
barrier to malloc.
