Subject: Add cmpxchg_local to avr32
X-Git-Tag: v2.6.25-rc1~346
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5e86c11d3eb4662000f3ced7344352b2ca319d03;p=pandora-kernel.git

Add cmpxchg_local to avr32

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.
