git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty Here are some tty/serial patches for 3.3-rc1 Big thing here is the movement of the 8250 serial drivers to their own directory, now that the patch churn has calmed down. Other than that, only minor stuff (omap patches were reverted as they were found to be wrong), and another broken driver removed from the system.

2012-01-31Prevent DM RAID from loading bitmap twice.Jonathan Brassow
The life cycle of a device-mapper target is: 1) create 2) resume 3) suspend *) possibly repeat from 2 4) destroy The dm-raid target is unconditionally calling MD's bitmap_load function upon every resume. If steps 2 & 3 above are repeated, bitmap_load is called multiple times. It is only written to be called once; otherwise, it allocates new memory for the bitmap (without freeing the old) and incrementing the number of pages it thinks it has without zeroing first. This ultimately leads to access beyond allocated memory and lost memory. Simply avoiding the bitmap_load call upon resume is not sufficient. If the target was suspended while the initial recovery was only partially complete, it needs to be restarted when the target is resumed. This is why 'md_wakeup_thread' is called before issuing the 'mddev_resume'. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>

The PCIe device FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd FireWire Host Controller [1180:e832] (prog-if 10 [OHCI]) is unable to access attached FireWire devices when MSI is enabled but works if MSI is disabled. http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28251.html Hence add the "disable MSI" quirks flag for this device, or in fact for safety and simplicity for all current (R5U230, R5U231, R5U240) and future Ricoh PCIe 1394 controllers.

1) Setting link attributes can modify the size of the attributes that would be reported on a subsequent getlink netlink operation, therefore min_ifinfo_dump_size needs to be adjusted. From Stefan Gula. 2) Resegmentation of TSO frames while trimming can violate invariants expected by callers, namely that the number of segments can only stay the same or decrease, never increase. If MSS changes, however, we can trim data but then end up with more segments. Fix this by only segmenting to the MSS already recorded in the SKB. That's the simplest fix for now and if we want to get more fancy in the future that's a more involved change. This probably explains some retransmit counter inaccuracies. From Neal Cardwell. 3) Fix too-many-wakeups in POLL with AF_UNIX sockets, from Eric Dumazet. 4) Fix CAIF crashes wrt. namespace handling. From Eric Dumazet and Eric W.

2012-01-30mtd: fix MTD suspendArtem Bityutskiy
Commits 3fe4bae88460869a8e553397cd9057a4ee7ca341 and 079c985e7a6f4ce60f931cebfdd5ee3c3 broke MTD suspend in 2 ways: 1. When the '->suspend' method is not present, we return -EOPNOTSUPP, but the callers of 'mtd_suspend()' expects 0 instead. 2. Checking of the 'mtd' parameter against NULL has been incorrectly removed in 'mtd_cls_suspend()'. This patch fixes the breakages. This has been found, analyzed, reported and tested by Rafael J. Wysocki <rjw@sisk.pl>. Note, this patch is not needed in the stable tree because it causes a regression introduced during the v3.3 merge window. Reported-by: Rafael J.

The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument.

This should fix the issue reported by Alfonso Fiore where booting with only a HDMI cable connected to his TV failed to display anything. The issue is that the bios set up things for 1080i and used the pannel fitter to scale up the lower progressive resolutions.

2012-01-27RDMA/ucma: Discard all events for new connections until acceptedSean Hefty
After reporting a new connection request to user space, the rdma_ucm will discard subsequent events until the user has associated a user space idenfier with the kernel cm_id. This is needed to avoid reporting a reject/disconnect event to the user for a request that they may not have processed. The user space identifier is set once the user tries to accept the connection request. However, the following race exists in ucma_accept(): ctx->uid = cmd.uid; <events may be reported now> ret = rdma_accept(ctx->cm_id, ...); Once ctx->uid has been set, new events may be reported to the user. While the above mentioned race is avoided, there is an issue that the user _may_ receive a reject/disconnect event if rdma_accept() fails, depending on when the event is processed. To simplify the use of rdma_accept(), discard all events unless rdma_accept() succeeds. This problem was discovered based on questions from Roland Dreier <roland@purestorage.com>.

Commit 8d4548f2b ("IB/qib: Default some module parameters optimally") introduced an issue with older root complexes. They cannot handle the pcie_caps of 0x51 (MaxReadReq 4096, MaxPayload=256). A typical diagnostic in this situation reported by syslog contains the text: [PCIe Poisoned TLP][Send DMA memory read] Restore the module paramter default to zero with will avoid any changes in the root complex.

2012-01-27RDMA/core: Fix kernel panic by always initializing qp->usecntBernd Schubert
We have just been investigating kernel panics related to cq->ibcq.event_handler() completion calls. The problem is that ib_destroy_qp() fails with -EBUSY. Further investigation revealed qp->usecnt is not initialized. This counter was introduced in linux-3.2 by commit 0e0ec7e0638e ("RDMA/core: Export ib_open_qp() to share XRC TGT QPs") but it only gets initialized for IB_QPT_XRC_TGT, but it is checked in ib_destroy_qp() for any QP type. Fix this by initializing qp->usecnt for every QP we create.
