| * b44: Use kernel DMA addresses for the kernel DMA APIMichael Buesch2009-04-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | We must not use the device DMA addresses for the kernel DMA API, because device DMA addresses have an additional offset added for the SSB translation. Use the original dma_addr_t for the sync operation. Cc: stable@kernel.org Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | The ibm_newemac driver includes code which assumes that the work_struct which is included in every delayed_work is the first member of that structure. This is currently the case but might change in the future, so use to_delayed_work() instead, which doesn't make such an assumption.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the device is disconnected, the dev structure goes away, so trying to report another error via dev_printk is bound to oops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | e1000 (and e1000e, igb, ixgbe, ixgb) all do a series of operations each time a multicast address is added. The flow goes something like 1) stack adds one multicast address 2) stack passes whole current list of unicast and multicast addresses to driver 3) driver clears entire list in hardware 4) driver programs each multicast address using iomem in a loop This was causing multicast packets to be lost during the reprogramming process. reference with test program: http://kerneltrap.org/mailarchive/linux-netdev/2009/3/14/5160514/thread Thanks to Dave Boutcher for his report and test program.

| * | | [MTD] [NAND] FSL-UPM: Add wait flags to support board/chip specific delaysWolfgang Grandegger2009-04-061-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The existing driver uses similar fixed delay points. To manage these extra delays in a more general way, I introduced the "fsl,ump-wait-flags" property allowing the board- specific driver to specify various types of extra delay.

MTD drivers should set the dev.parent field to point to the physical device, before setting up partitions or otherwise declaring MTDs. - Those device nodes always map to /sys/class/mtdX device nodes, which no longer depend on MTD_CHARDEV. - Those mtdX sysfs nodes have a "starter set" of attributes; it's not yet sufficient to replace /proc/mtd. - Enabling MTD_CHARDEV provides /sys/class/mtdXro/ nodes and the /sys/class/mtd*/dev attributes (for udev, mdev, etc). - Include a MODULE_ALIAS_CHARDEV_MAJOR macro. It'll work with udev creating the /dev/mtd* nodes, not just a static rootfs. So the sysfs structure is pretty much what you'd expect, except that readonly chardev nodes are a bit quirky.

| * | | NOMMU: Add support for direct mapping through mtdconcat if possibleDavid Howells2009-03-241-0/+47

It has some restrictions: (1) It won't permit direct mapping of concatenated devices that have differing BDIs. (2) It doesn't support maps that span the 'gap' between devices, although it possibly could if the devices spanned across return compatible (ie. contiguous) addresses from their get_unmapped_area() ops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OneNAND write-while-program method of writing improves performance, compared with ordinary writes, by transferring data to OneNAND's RAM buffers atthe same time as programming the NAND core. When writing several NAND pages at a time, an improvement of 12% to 25% is seen.

Formerly, the MTD selected for mtdoops was done only by index number. With this patch, a name can be used instead. For example, the kernel command line: console=ttyMTD5 selects MTD 5 for mtdoops. But now this is also possible: console=ttyMTD,log which selects the MTD named "log" for mtdoops. This has the advantage that partitions can be added or removed that would affect the MTD index number but not the name, without having to then change the kernel command line.
