Apple decided to copy some USB stupidity over to FireWire. The sector number returned by iPods from read_capacity is one too many. This may cause I/O errors, especially if the kernel is configured for EFI partition support. We use the same workaround as usb-storage but have to check for different model IDs. http://marc.theaimsgroup.com/?t=114233262300001 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187409 Acknowledgements: Diagnosis and therapy by Mathieu Chouquet-Stringer <ml2news@free.fr>, additional data about affected and unaffected Apple hardware from Vladimir Kotal, Sander De Graaf, Bryan Olmstead and Hugh Dixon.

Grand unification of the three types of workarounds we have so far. The "skip mode page 8" workaround is now limited to devices which pretend to be of TYPE_DISK instead of TYPE_RBC. This workaround is no longer enabled for Initio bridges. Patch update in anticipation of more workarounds: - Add module parameter "workarounds". - Deprecate parameter "force_inquiry_hack". - Compose the blacklist of a compound type for better readability and extensibility. - Remove a now unused #define.

From: "Angelo P. Castellani" <angelo.castellani+lkml@gmail.com> Using NewReno, if a sk_buff is timed out and is accounted as lost_out, it should also be removed from the sacked_out. This is necessary because recovery using NewReno fast retransmit could take up to a lot RTTs and the sk_buff RTO can expire without actually being really lost. left_out = sacked_out + lost_out in_flight = packets_out - left_out + retrans_out Using NewReno without this patch, on very large network losses, left_out becames bigger than packets_out + retrans_out (!!). For this reason unsigned integer in_flight overflows to 2^32 - something. Signed-off-by: David S. Miller <davem@davemloft.net>

This fixes two problems triggered by the MMC stack updating clocks: - SPI masters driver should accept a max clock speed of zero; that's one convention for marking idle devices. (Presumably that helps controllers that don't autogate clocks to "off" when not in use.) - There are more than 1000 nanoseconds per millisecond; setting the clock down to 125 KHz now works properly. Showing once again that Zero (http://en.wikipedia.org/wiki/Zero) is still an inexhaustible number of bugs.

We need to be able to have a "SPI bus 0" matching chip numbering; but that number was wrongly used to flag dynamic allocation of a bus number. This patch resolves that issue; now negative numbers trigger dynamic alloc. It also updates the how-to-write-a-controller-driver overview to mention this stuff.

This driver turns a PXA2xx synchronous serial port (SSP) into a SPI master controller (see Documentation/spi/spi_summary).

Imre Deak authored
Some protocols (like one for some bitmap displays) require different clock speed or word size settings for each transfer in an SPI message. This adds those parameters to struct spi_transfer. They are to be used when they are nonzero; otherwise the defaults from spi_device are to be used. The patch also adds a setup_transfer callback to spi_bitbang, uses it for messages that use those overrides, and implements it so that the pure bitbanging code can help resolve any questions about how it should work.

With CONFIG_NUMA set, kmem_cache_destroy() may fail and say "Can't free all objects." The problem is caused by sequences such as the following (suppose we are on a NUMA machine with two nodes, 0 and 1): * Allocate an object from cache on node 0. * Free the object on node 1. The object is put into node 1's alien array_cache for node 0. * Call kmem_cache_destroy(), which ultimately ends up in __cache_shrink(). * __cache_shrink() does drain_cpu_caches(), which loops through all nodes. For each node it drains the shared array_cache and then handles the alien array_cache for the other node. However this means that node 0's shared array_cache will be drained, and then node 1 will move the contents of its alien[0] array_cache into that same shared array_cache. node 0's shared array_cache is never looked at again, so the objects left there will appear to be in use when __cache_shrink() calls __node_shrink() for node 0. So __node_shrink() will return 1 and kmem_cache_destroy() will fail. This patch fixes this by having drain_cpu_caches() do drain_alien_cache() on every node before it does drain_array() on the nodes' shared array_caches. The problem was originally reported by Or Gerlitz <ogerlitz@voltaire.com>.
