Subject: - add-cmpxchg_local-to-avr32.patch removed from -mm tree
Date: Wed, 31 Oct 2007 15:41:00 -0700	[thread overview]
Message-ID: <20071031224100.8595E432BF5@localhost> (raw)


The patch titled
     Add cmpxchg_local to avr32
has been removed from the -mm tree.  Its filename was
     add-cmpxchg_local-to-avr32.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
Subject: Add cmpxchg_local to avr32
From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

Use the new generic cmpxchg_local (disables interrupt) for 8, 16 and 64 bits
cmpxchg_local. Use the __cmpxchg_u32 primitive for 32 bits cmpxchg_local.

Note that cmpxchg only uses the __cmpxchg_u32 or __cmpxchg_u64 and will cause
a linker error if called with 8 or 16 bits argument.
