cpufreq init can be called when a CPU is set online. Need to make powernow-k8's initialisation functions __cpuinit to prevents oopses when a CPU is off/onlined on a AMD system Cc: trenn@suse.de Cc: mark.langsdorf@amd.com Cc: davej@redhat.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* Large directories are structured around Btrees where all the data
* elements are in the leaf nodes. Filenames are hashed into an int,
* then that int is used as the index into the Btree. Since the hashval
* of a filename may not be unique, we may have duplicate keys. The
* internal links in the Btree are logical block offsets into the file.
*
* Small directories use a different format and are packed as tightly
* as possible so as to fit into the literal area of the inode.
