Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: [SPARC]: Add iomap interfaces. [OPENPROM]: Rewrite driver to use in-kernel device tree. [OPENPROMFS]: Rewrite using in-kernel device tree and seq_file. [SPARC]: Add unique device_node IDs and a ".node" property. [SPARC]: Add of_set_property() interface. [SPARC64]: Export auxio_register to modules. [SPARC64]: Add missing interfaces to dma-mapping.h [SPARC64]: Export _PAGE_IE to modules. [SPARC64]: Allow floppy driver to build modular. [SPARC]: Export x_bus_type to modules. [RIOWATCHDOG]: Fix the build. [CPWATCHDOG]: Fix the build. [PARPORT] sunbpp: Fix typo. [MTD] sun_uflash: Port to new EBUS device layer.
