Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: NMartin K.

DDR2 memory DIMMs on the Axon could be accessed only as one partition when using file system drivers which are using the direct_access() method. This patch enables for such file system drivers to access Axon's DDR2 memory even if it is splitted in several partitions.

Axonram module registers one block device for each DDR2 DIMM found on a system. This means that each DDR2 DIMM becomes its own block device major number. This patch lets axonram module to register the only one block device for all DDR2 DIMMs which also spares kernel resources.

Alter the block device ->direct_access() API to work with the new get_xip_mem() API (that requires both kaddr and pfn are returned). Some architectures will not do the right thing in their virt_to_page() for use by XIP (to translate from the kernel virtual address returned by direct_access(), to a user mappable pfn in XIP's page fault handler. However, we can't switch it to just return the pfn and not the kaddr, because we have no good way to get a kva from a pfn, and XIP requires the kva for its read(2) and write(2) handlers. So we have to return both.

Firmware would not deliver two interrupt numbers in device-tree any more but only one, for correctable ECC, because uncorrectable ECC from now is handled by firmware itself. Changes in the axonram module are necessary because in the old version, if it is not allowed to fetch the second interrupt number from device-tree, it interpretes this as an error case and exits.

The Axon bridge chip used on new Cell/B.E. based blade servers comes with a DDR2 memory controller that can be used to attach cheap memory modules, as opposed to the high-speed XDR memory that is used by the CPU itself. Since the memory controller does not participate in the cache coherency protocol, we can not use the memory direcly for Linux applications, but by providing a block device it can be used for swap space, temporary file storage and through the use of the direct_access block device operation for mapping into user addresses, when it is mounted with an appropriate file system.
