When we cannot mark nodes as obsolete, such as on NAND flash, we end up having to delete inodes with !nlink in jffs2_build_remove_unlinked_inode(). However, jffs2_build_xattr_subsystem() runs later than this, and will attach an xref to the dead inode. Then later when the last nodes of that dead inode are erased we hit a BUG() in jffs2_del_ino_cache() because we're not supposed to get there with an xattr still attached to the inode which is being killed. The simple fix is to refrain from attaching xattrs to inodes with zero nlink, in jffs2_build_xattr_subsystem(). It's it's OK to trust nlink here because the file system isn't actually mounted yet, so there's no chance that a zero-nlink file could actually be alive still because it's open.

The cheesy uclinux mtd maps can be used for more than just the root device, so I think we should drop the forcing. Also, I feel like this is a policy decision that shouldnt be in the kernel in the first place. People who have been lazy and boot with uclinux mtd maps and dont put root= into their commandline can simply add the appropriate root= line either into their bootloader or into the compiled in bootargs.

drivers/mtd/maps includes flash maps for the Beech and Arctic PowerPC 405LP based boards. However, the 405LP was discontinued before any quantity were distributed and those boards no longer have kernel support in general. Therefore, this patch removes this obsolete code.

We attempted to insert new nodes into the tree by just using rb_replace_node to let them replace an earlier node which they completely overlapped. However, that could place the new node into the wrong place in the tree, since its start could be node only before the start of the victim, but before the node _before_ the victim in the tree (if that previous node actually ends _after_ the new node, thus isn't entirely overlapped and wasn't itself chosen to be the victim).

The original code would remember, during the first pass over the tree, a suitable place to start the insertion from when we eventually come to add a new node. The optimisation was broken, and we sometimes ended up inserting a new node in the wrong place because we started the insertion from the wrong point. Just ditch the optimisation and start the insertion from the root of the tree, for now. I'll try it again when I'm feeling cleverer. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

The CAFÉ can handle two chip on separate chipselect lines. Hook up the undocumented chipselect bits in the driver and probe both. In the case of OLPC, it's not actually two separate devices -- it's a single '1GiB' package with two 512MiB dies internally. So clear the NAND_BBT_PERCHIP flag to treat it as a single chip for BBT purposes, and make life easier for the firmware. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

Freescale high-speed USB SOC can be found on some Freescale processors among different architectures. It supports both host and device functions. This driver adds its device support for Linux USB Gadget layer. It is tested on MPC8349 and MPC8313, but should work on other platforms with minor tweaks. The driver passed USBCV 1.3 compliance tests. Note that this driver doesn't yet include OTG support.

The driver uses usb_control_msg() for exchanging data with the device. When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the timeouts for these calls where set to 5*HZ for reading, 1HZ for writing. (These timeouts seemed to work fine for all users of the driver, at least nobody complained in the last 2 years. The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and left the driver with 5 jiffies for reading and 1 jiffy for writing. My new machine is fast, but not that fast. The patch also removes a useless debug statement, which was left over from testing a broken firmware version From: Eberhard Fahle <e.fahle@wayoda.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
