commit 2995fa78 upstream. This reverts commit be35f486 ("dm: wait until embedded kobject is released before destroying a device") and provides an improved fix. The kobject release code that calls the completion must be placed in a non-module file, otherwise there is a module unload race (if the process calling dm_kobject_release is preempted and the DM module unloaded after the completion is triggered, but before dm_kobject_release returns). To fix this race, this patch moves the completion code to dm-builtin.c which is always compiled directly into the kernel if BLK_DEV_DM is selected. The patch introduces a new dm_kobject_holder structure, its purpose is to keep the completion and kobject in one place, so that it can be accessed from non-module code without the need to export the layout of struct mapped_device to that code.

commit feffe09f upstream. According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB register error issue", All USB register write operations must use the ARM SWP instruction. So, we implement a special ehci_write for imx28. Discussion for it at below: http://marc.info/?l=linux-usb&m=137996395529294&w=2 Without this patcheset, imx28 works unstable at high AHB bus loading. If the bus loading is not high, the imx28 usb can work well at the most of time. There is a IC errata for this problem, usually, we consider IC errata is a problem not a new feature, and this workaround is needed for that, so we need to add them to stable tree 3.11+.

commit a4c35ed2 upstream. The synchronization needed after ftrace_ops are unregistered must happen after the callback is disabled from becing called by functions. The current location happens after the function is being removed from the internal lists, but not after the function callbacks were disabled, leaving the functions susceptible of being called after their callbacks are freed. This affects perf and any externel users of function tracing (LTTng and SystemTap). Fixes: cdbe61bf "ftrace: Allow dynamically allocated function tracers" Signed-off-by:

commit 7614c3dc upstream. The function tracer uses preempt_disable/enable_notrace() for synchronization between reading registered ftrace_ops and unregistering them. Most of the ftrace_ops are global permanent structures that do not require this synchronization. That is, ops may be added and removed from the hlist but are never freed, and wont hurt if a synchronization is missed. But this is not true for dynamically created ftrace_ops or control_ops, which are used by the perf function tracing. The problem here is that the function tracer can be used to trace kernel/user context switches as well as going to and from idle. Basically, it can be used to trace blind spots of the RCU subsystem. This means that even though preempt_disable() is done, a synchronize_sched() will ignore CPUs that haven't made it out of user space or idle. These can include functions that are being traced just before entering or exiting the kernel sections. To implement the RCU synchronization, instead of using synchronize_sched() the use of schedule_on_each_cpu() is performed. This means that when a dynamically allocated ftrace_ops, or a control ops is being unregistered, all CPUs must be touched and execute a ftrace_sync() stub function via the work queues. This will rip CPUs out from idle or in dynamic tick mode. This only happens when a user disables perf function tracing or other dynamically allocated function tracers, but it allows us to continue to debug RCU and context tracking with function tracing.

commit 66b512ed upstream. With some SDIO devices, timeout errors can happen when reading data. To solve this issue, the DMA transfer has to be activated before sending the command to the device. This order is incorrect in PDC mode. So we have to take care if we are using DMA or PDC to know when to send the MMC command. Signed-off-by:

commit 80ab8eae upstream. The PCI devices with DMA masks smaller than 32bit should enable CONFIG_ZONE_DMA. Since the recent change of page allocator, page allocations via dma_alloc_coherent() with the limited DMA mask bits may fail more frequently, ended up with no available buffers, when CONFIG_ZONE_DMA isn't enabled. With CONFIG_ZONE_DMA, the system has much more chance to obtain such pages. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=68221Signed-off-by:

Otherwise extend can fail, e.g.: sm_metadata_extend call sequence that fails: -> sm_ll_extend -> dm_tm_new_block -> dm_sm_new_block -> sm_bootstrap_new_block => returns -ENOSPC because smm->begin == smm->ll.nr_blocks Signed-off-by:

commit be35f486 upstream. There may be other parts of the kernel holding a reference on the dm kobject. We must wait until all references are dropped before deallocating the mapped_device structure. The dm_kobject_release method signals that all references are dropped via completion. But dm_kobject_release doesn't free the kobject (which is embedded in the mapped_device structure). This is the sequence of operations: * when destroying a DM device, call kobject_put from dm_sysfs_exit * wait until all users stop using the kobject, when it happens the release method is called * the release method signals the completion and should return without delay * the dm device removal code that waits on the completion continues * the dm device removal code drops the dm_mod reference the device had * the dm device removal code frees the mapped_device structure that contains the kobject Using kobject this way should avoid the module unload race that was mentioned at the beginning of this thread: https://lkml.org/lkml/2014/1/4/83Signed-off-by:

commit 3685f19e upstream. Tegra chips have 4 or 5 identical UART modules embedded. UARTs C..E have their MODEM-control signals tied off to a static state. However UARTs A and B can optionally route those signals to/from package pins, depending on the exact pinmux configuration. When these signals are not routed to package pins, false interrupts may trigger either temporarily, or permanently, all while not showing up in the IIR; it will read as NO_INT. This will eventually lead to the UART IRQ being disabled due to unhandled interrupts. When this happens, the kernel may print e.g.: irq 68: nobody cared (try booting with the "irqpoll" option) In order to prevent this, enable UART_BUG_NOMSR. This prevents UART_IER_MSI from being enabled, which prevents the false interrupts from triggering. In practice, this is not needed under any of the following conditions: * On Tegra chips after Tegra30, since the HW bug has apparently been fixed. * On UARTs C..E since their MODEM control signals are tied to the correct static state which doesn't trigger the issue. * On UARTs A..B if the MODEM control signals are routed out to package pins, since they will then carry valid signals. However, we ignore these exceptions for now, since they are only relevant if a board actually hooks up more than a 4-wire UART, and no currently supported board does this. If we ever support a board that does, we can refine the algorithm that enables UART_BUG_NOMSR to take those exceptions into account, and/or read a flag from DT/... that indicates that the board has hooked up and pinmux'd more than a 4-wire UART.

commit c1f15196 upstream. Genuine FTDI chips support only CS7/8. A previous fix in commit 8704211f ("USB: ftdi_sio: fixed handling of unsupported CSIZE setting") enforced this limitation and reported it back to userspace. However, certain types of smartcard readers depend on specific driver behaviour that requests 0 data bits (not 5) to change into a different operating mode if CS5 has been set. This patch reenables this behaviour for all FTDI devices. Tagged to be added to stable, because it affects a lot of users of embedded systems which rely on these readers to work properly.

commit 6ff33b7d upstream. When a task enters call_refreshresult with status 0 from call_refresh and !rpcauth_uptodatecred(task) it enters call_refresh again with no rate-limiting or max number of retries. Instead of trying forever, make use of the retry path that other errors use. This only seems to be possible when the crrefresh callback is gss_refresh_null, which only happens when destroying the context. To reproduce: 1) mount with sec=krb5 (or sec=sys with krb5 negotiated for non FSID specific operations). 2) reboot - the client will be stuck and will need to be hard rebooted BUG: soft lockup - CPU#0 stuck for 22s!

commit 623c8263 upstream. Some PL2303 devices are known to lose bytes if you change serial settings even to the same values as before. Avoid this by comparing the encoded settings with the previsouly used ones before configuring the device. The common case was fixed by commit bf5e5834 ("pl2303: Fix mode switching regression"), but this problem was still possible to trigger, for instance, by using the TCSETS2-interface to repeatedly request 115201 baud, which gets mapped to 115200 and thus always triggers a settings update.

The bug was introduced by commit 49e22585 ("slub: per cpu cache for partial pages"). We should use page->pages instead of page->pobjects when calculating the number of cpu partial slabs. This also fixes the mapping of slabs and nodes. As there's no variable storing the number of total/active objects in cpu partial slabs, and we don't have user interfaces requiring those statistics, I just add WARN_ON for those cases. Acked-by:

commit a7f84f03 upstream. Current code check boot service region with kernel text region by: start+size >= __pa_symbol(_text) The end of the above region should be start + size - 1 instead. I see this problem in ovmf + Fedora 19 grub boot: text start: 1000000 md start: 800000 md size: 800000 Signed-off-by:

commit 5ac64ba1 upstream. As the dvb-frontend kthread can be called anytime, it can race with some get status ioctl. So, it seems better to avoid one to race with the other while reading a 32 bits register. I can't see any other reason for having a mutex there at I2C, except to provide such kind of protection, as the I2C core already has a mutex to protect I2C transfers. Note: instead of this approach, it could eventually remove the dib8000 specific mutex for it, and either group the 4 ops into one xfer or to manually control the I2C mutex. The main advantage of the current approach is that the changes are smaller and more puntual. Signed-off-by:

commit dcaf9aed upstream. Bfa driver crash is observed while pushing the firmware on to chinook quad port card due to uninitialized bfi_image_ct2 access which gets initialized only for CT2 ASIC based cards after request_firmware(). For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting initialized as there is no check for chinook PCI device ID before request_firmware and instead bfi_image_cb is initialized as it is the default case for card type check. This patch includes changes to read the right firmware for quad port chinook. Signed-off-by:

commit d6a48452 upstream. In commit 85747f ("PATCH] parport: add NetMOS 9805 support") Max added the PCI ID for NetMOS 9805 based on a Debian bug report from 2k4 which was at the v2.4.26 time frame. The patch made into 2.6.14. Shortly before that patch akpm merged commit 296d3c78 ("[PATCH] Support NetMOS based PCI cards providing serial and parallel ports") which made into v2.6.9-rc1. Now we have two different entries for the same PCI id. I have here the NetMos 9805 which claims to support SPP/EPP/ECP mode. This patch takes Max's entry for titan_1284p1 (base != -1 specifies the ioport for ECP mode) and replaces akpm's entry for netmos_9805 which specified -1 (=none). Both share the same PCI-ID (my card has subsystem 0x1000 / 0x0020 so it should match PCI_ANY). While here I also drop the entry for titan_1284p2 which is the same as netmos_9815.

commit 5c6c2681 upstream. Due to difficulty in arriving at the proper security label for TCP SYN-ACK packets in selinux_ip_postroute(), we need to check packets while/before they are undergoing XFRM transforms instead of waiting until afterwards so that we can determine the correct security label.

commit c7848f69 upstream. decode_op_hdr() cannot distinguish between an XDR decoding error and the perfectly valid errorcode NFS4ERR_IO. This is normally not a problem, but for the particular case of OPEN, we need to be able to increment the NFSv4 open sequence id when the server returns a valid response. Reported-by:
