commit 296291cd upstream. Currently a simple program below issues a sendfile(2) system call which takes about 62 days to complete in my test KVM instance. int fd; off_t off = 0; fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644); ftruncate(fd, 2); lseek(fd, 0, SEEK_END); sendfile(fd, fd, &off, 0xfffffff); Now you should not ask kernel to do a stupid stuff like copying 256MB in 2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin should have a way to stop you. We actually do have a check for fatal_signal_pending() in generic_perform_write() which triggers in this path however because we always succeed in writing something before the check is done, we return value > 0 from generic_perform_write() and thus the information about signal gets lost. Fix the problem by doing the signal check before writing anything. That way generic_perform_write() returns -EINTR, the error gets propagated up and the sendfile loop terminates early. Signed-off-by:

commit 97aff2c0 upstream. There are 24 EQ registers not 25, I suspect this bug came about because the registers start at EQ1 not zero. The bug is relatively harmless as the extra register written is an unused one. Signed-off-by:

commit 8832317f upstream. Currently we do not validate rtas.entry before calling enter_rtas(). This leads to a kernel oops when user space calls rtas system call on a powernv platform (see below).

commit 2871c69e upstream. Commit 4c7e3093 ("dm btree remove: fix bug in redistribute3") wasn't a complete fix for redistribute3(). The redistribute3 function takes 3 btree nodes and shares out the entries evenly between them. If the three nodes in total contained (MAX_ENTRIES * 3) - 1 entries between them then this was erroneously getting rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 1) in the center. Fix this issue by being more careful about calculating the target number of entries for the left and right nodes.

commit 2c2b24d9 upstream. The dbx500_cpuidle_probe is tagged as an __init section but the variable dbx500_cpuidle_plat_driver is not. The dbx500_cpuidle_probe could not be declared as __init because of macro module_platform_driver builds the exit function, tags as __exit and this one refers to the dbx500_cpuidle_plat_driver which is an __initdata. That leads to a section mismatch. Fix it by removing the __init tag for the probe function. Signed-off-by:

commit 7868943d upstream. The following patch is required to resolve remote wake issues with certain devices. Issue description: If the remote wake is issued from the device in a specific timing condition while the system is entering sleep state then it may cause system to auto wake on subsequent sleep cycle. Root cause: Host controller rebroadcasts the Resume signal > 100 µseconds after receiving the original resume event from the device. For proper function, some devices may require the rebroadcast of resume event within the USB spec of 100µS. Workaroud: 1. Filter the AMD platforms with Yangtze chipset, then judge of all the usb devices are mouse or not. And get out the port id which attached a mouse with Pixart controller. 2. Then reset the port which attached issue device during system resume from S3. [Q] Why the special devices are only mice? Would high speed devices such as 3G modem or USB Bluetooth adapter trigger this issue? - Current this sensitivity is only confined to devices that use Pixart controllers. This controller is designed for use with LS mouse devices only. We have not observed any other devices failing. There may be a small risk for other devices also but this patch (reset device in resume phase) will cover the cases if required. [Q] Shouldn’t the resume signal be sent within 100 us for every device? - The Host controller may not send the resume signal within 100us, this our host controller specification change. This is why we require the patch to prevent side effects on certain known devices. [Q] Why would clicking mouse INTENSELY to wake the system up trigger this issue? - This behavior is specific to the devices that use Pixart controller. It is timing dependent on when the resume event is triggered during the sleep state. [Q] Is it a host controller issue or mouse? - It is the host controller behavior during resume that triggers the device incorrect behavior on the next resume. This patch sets USB_QUIRK_RESET_RESUME flag for these Pixart-based mice when they attached to platforms with AMD Yangtze chipset. Signed-off-by:

commit cb83df77 upstream. 1. set AUTOREQ to NONE at the beginning of teardown; 2. add delay for dma pipeline to drain; 3. Do not set USB_TDOWN bit for RX teardown. The CPPI hw has an issue that when tearing down a RX channel, if another RX channel is receiving data, the CPPI will lockup. To workaround the issue, do not set the CPPI TD bit. The steps before this point ensures the CPPI channel will be torn down properly. Signed-off-by:

commit 8ae25a35 upstream. The scanner (here DS3508) always returns 64 bytes per urb buffer. The first byte indicates the data length used in the current buffer. There even was a comment describing this. But the comment also said that we'll send everything in the buffer to the tty layer. That means sending the actual barcode data and lots of trailing zeroes. This patch lets the driver only send the real data. Signed-off-by:

commit 874bbfe6 upstream. My system keeps crashing with below message. vmstat_update() schedules a delayed work in current cpu and expects the work runs in the cpu. schedule_delayed_work() is expected to make delayed work run in local cpu. The problem is timer can be migrated with NO_HZ. __queue_work() queues work in timer handler, which could run in a different cpu other than where the delayed work is scheduled. The end result is the delayed work runs in different cpu. The patch makes __queue_delayed_work records local cpu earlier. Where the timer runs doesn't change where the work runs with the change.

commit 56d4b8a2 upstream. ACPI SSCN/FMCN methods were originally added because then the platform can provide the most accurate HCNT/LCNT values to the driver. However, this seems not to be true for Dell Inspiron 7348 where using these causes the touchpad to fail in boot: i2c_hid i2c-DLL0675:00: failed to retrieve report from device. i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration i2c_hid i2c-DLL0675:00: failed to retrieve report from device. i2c_designware INT3433:00: controller timed out The values received from ACPI are (in fast mode): HCNT: 72 LCNT: 160 this translates to following timings (input clock is 100MHz on Broadwell): tHIGH: 720 ns (spec min 600 ns) tLOW: 1600 ns (spec min 1300 ns) Bus period: 2920 ns (assuming 300 ns tf and tr) Bus speed: 342.5 kHz Both tHIGH and tLOW are within the I2C specification. The calculated values when ACPI parameters are not used are (in fast mode): HCNT: 87 LCNT: 159 which translates to: tHIGH: 870 ns (spec min 600 ns) tLOW: 1590 ns (spec min 1300 ns) Bus period 3060 ns (assuming 300 ns tf and tr) Bus speed 326.8 kHz These values are also within the I2C specification. Since both ACPI and calculated values meet the I2C specification timing requirements it is hard to say why the touchpad does not function properly with the ACPI values except that the bus speed is higher in this case (but still well below the max 400kHz). Solve this by adding DMI quirk to the driver that disables using ACPI parameters on this particulare machine. Reported-by:

commit eadd709f upstream. The core may register clients attached to this master which may use funtionality from the master. So, RuntimePM must be enabled before, otherwise this will fail. While here, move drvdata, too. Signed-off-by:

commit b6dd8e07 upstream. Commit df057cc7 ("arm64: errata: add module build workaround for erratum #843419") sets CFLAGS_MODULE to ensure that the large memory model is used by the compiler when building kernel modules. However, CFLAGS_MODULE is an environment variable and intended to be overridden on the command line, which appears to be the case with the Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.
