2008-02-19fix historic ioremap() abuse in AGPArjan van dev Ven
Several AGP drivers right now use ioremap_nocache() on kernel ram in order to turn a page of regular memory uncached. There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.

2008-02-19ide-cd: fix missing residual count setting in DMA modeKiyoshi Ueda
This patch fixes the missing residual count setting in DMA mode, which was introduced during the conversion to blk-end-request. The residual count could be used by the request submitter. So if it isn't set correctly, some upper layers does not work. (e.g. wodim for CD burning.) The bug is in only DMA mode. In PIO mode, we are setting the residual count correctly, so no need to fix.

2008-02-19ht6560b: force prefetch for some devicesJan Evert van Grootheest
Prefetch needs to be set for some ide devices to work when connected to a ht6560b interface. This was not always done properly, causing a system with a HD and CD on the primary interface to not work properly. Or, in effect, hang hard. This patch forces prefetch on devices before checking whether it is necessary to change the settings in the interface This patch should also be applied to 2.4. I don't currently have a 2.4 tree around.

2008-02-18RDMA/nes: Fix possible array overrunRoland Dreier
In nes_create_qp(), the test if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) { is used to error out if the db_index is too large; however, if the test doesn't trigger, then the index is used as nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp; and mmap_nesqp is declared as struct nes_qp *mmap_nesqp[NES_MAX_USER_WQ_REGIONS]; which leads to an array overrun if the index is exactly equal to NES_MAX_USER_WQ_REGIONS. Fix this by bailing out if the index is greater than or equal to NES_MAX_USER_WQ_REGIONS. This was spotted by the Coverity checker (CID 2162).

2008-02-18V4L/DVB (7188): radio-si470x version 1.0.6Tobias Lorenz
This patch combines all the finished discussions and its resulting patches from the mailing list. The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of small issues, that are fixed with this patch now. For me the most interesting thing is, that it's now safer to use it on other architectures. The history for version 1.0.6 is: - fixed coverity checker warnings in *_usb_driver_disconnect - probe()/open() race by correct ordering in probe() - DMA coherency rules by separate allocation of all buffers - use of endianness macros - abuse of spinlock, replaced by mutex - racy handling of timer in disconnect, replaced by delayed_work - racy interruptible_sleep_on(), replaced with wait_event_interruptible() - handle signals in read() The driver is tested with all Debian/testing radio programs and rdsd.

2008-02-18V4L/DVB (7179): Allow more than one em28xx boardMauro Carvalho Chehab
em28xx driver is capable of handling more than one usb device. However, isoc transfers require a large amount of data to be transfered. Before this patch, just one em28xx board were enough to allocate more than 50% URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=480/800 us (60%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, only one board could use an USB host at the same time. After the patch, it is possible to use more than one em28xx at the same time, on the same usb host, if the image size is slower or equal to 345600, since those images will require about 30% of the URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=232/800 us (29%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, in thesis, after the patch, it would be possible to use up to 3 boards by each usb host, if the devices are generating small images.
