Message-ID: <200802080808.m1888lsf014695@imap1.linux-foundation.org> (raw)


The patch titled
     Add cmpxchg_local to parisc
has been removed from the -mm tree.  Its filename was
     add-cmpxchg_local-to-parisc.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: Add cmpxchg_local to parisc
From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

Use the new generic cmpxchg_local (disables interrupt). Also use the generic
cmpxchg as fallback if SMP is not set.
