Source for native sun.misc.Unsafe operations in java

i've downloaded "openjdk-6-src-b23-05_jul_2011" to have a look at the native implementations for the methods in sun.misc.Unsafe. e.g. compareAndSwapInt(...) but i am not able find anything in the downloaded sources of openjdk. i want to get an idea how these methods look like (i was interested in the atomic stuff the jdk provides).
could anybody point me to the right location(s)?
$ ls jdk/src/
linux share solaris windows
$ ls hotspot/src/os/
linux posix solaris windows
any help appreciated

Implementation of unsafe methods itself is not OS-specific, therefore it can be found in hotspot/src/share/vm/prims/unsafe.cpp. It delegates to hotspot/src/share/vm/runtime/atomic.cpp, which includes OS and CPU specific files, such as hotspot/src/os_cpu/windows_x86/atomic_windows_x86.inline.hpp.

Examples of forcing the release of native direct memory ByteBuffer assigned, using sun.misc.Unsafe?
JDK provides abillity to allocate so-called direct ByteBuffers, where memory is allocate outside of Java heap. This can be beneficial since this memory is not touched by garbage collector, and as such does not contribute to GC overhead: this is a ver
