* UBI: fix backward compatibilityArtem Bityutskiy2009-10-20
| | | | | | | | | | | | | Commit 32bc4820287a1a03982979515949e8ea56eac641 did not fully fix the backward compatibility issues. We still fail to properly handle situations when the first PEB contains non-zero image sequence number, but one of the following PEBs contains zero image sequence number. For example, this may happen if we mount a new image with an old kernel, and then try to mount it in the new kernel. This patch should fix the issue.

* block: use normal I/O path for discard requestsChristoph Hellwig2009-10-01
| | | | | | | | | | | | | | | | | | | | | | | | prepare_discard_fn() was being called in a place where memory allocation was effectively impossible. This makes it inappropriate for all but the most trivial translations of Linux's DISCARD operation to the block command set. Additionally adding a payload there makes the ownership of the bio backing unclear as it's now allocated by the device driver and not the submitter as usual. It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether the queue supports discard operations or not. blkdev_issue_discard now allocates a one-page, sector-length payload which is the right thing for the common ATA and SCSI implementations. The mtd implementation of prepare_discard_fn() is replaced with simply checking for the request being a discard. Largely based on a previous patch from Matthew Wilcox <matthew@wil.cx> which did the prepare_discard_fn but not the different payload allocation yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error handling in the phram driver is pretty bad -- in many places, errors are silently ignored or logged, but then still ignored in the return value.

If everything does go smoothly, rather than exit silently, dump a helpful info message like pretty much every other MTD driver does.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the ARM dependency from the generic "onenand" platform device driver. This change makes the driver useful for other architectures as well. Needed for the SuperH kfr2r09 board. Apart from the obvious Kconfig bits, the most important change is the move away from ARM specific includes and platform data. Together with this change the only in-tree board code gets an update, and the driver name is also changed gracefully break potential out of tree drivers. The driver is also updated to allow NULL as platform data together with a few changes to make use of resource_size() and dev_name().

| * | mtd: nand: register orion_nand using platform_driver_probe()Uwe Kleine-König2009-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | orion_nand_probe lives in .init.text, so using platform_driver_register to register it is wrong because binding a device after the init memory is discarded (e.g. via sysfs) results in an oops. As requested by Nicolas Pitre platform_driver_probe is used instead of moving the probe function to .devinit.text as proposed initially. This saves some memory, but devices registered after the driver is probed are not bound (probably there are none) and binding via sysfs isn't possible.
