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 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 avr32
From: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxx>
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.
