The patch titled
Add cmpxchg64 and cmpxchg64_local to x86_64
has been removed from the -mm tree. Its filename was
add-cmpxchg64-and-cmpxchg64_local-to-x86_64.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: Add cmpxchg64 and cmpxchg64_local to x86_64
From: Mathieu Desnoyers <[EMAIL PROTECTED]>
Make sure that at least cmpxchg64_local is available on all architectures to use
for unsigned long long values.
