2018-08-15ubifs: Turn two ubifs_assert() into a WARN_ON()Richard Weinberger
We are going to pass struct ubifs_info to ubifs_assert() but while unloading the UBIFS module we don't have the info struct anymore. Therefore replace the asserts by a regular WARN_ON(). Signed-off-by: Richard Weinberger <richard@nod.at>
2018-08-15ubi: expose the volume CRC check skip flagQuentin Schulz
Now that we have the logic for skipping CRC check for static UBI volumes in the core, let's expose it to users. This makes use of a padding byte in the volume description data structure as a flag. This flag only tell for now whether we should skip the CRC check of a volume. This checks the UBI volume for which we are trying to skip the CRC check is static. Let's also make sure that the flags passed to verify_mkvol_req are valid. We voluntarily do not take into account the skip_check flag in vol_cdev_write() as we want to make sure what we wrote was correctly written.

2018-08-15ubi: provide a way to skip CRC checksQuentin Schulz
Some users of static UBI volumes implement their own integrity check, thus making the volume CRC check done at open time useless. For instance, this is the case when one use the ubiblock + dm-verity + squashfs combination, where dm-verity already checks integrity of the block device but this time at the block granularity instead of verifying the whole volume. Skipping this test drastically improves the boot-time.

2018-08-14ACPICA: Clear status of all events when entering sleep statesRafael J. Wysocki
Commit fa85015c0d95 (ACPICA: Clear status of all events when entering S5) made the sleep state entry code in ACPICA clear the status of all ACPI events when entering S5 to fix a functional regression reported against commit 18996f2db918 (ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume). However, it is reported now that the regression also affects system states other than S5 on some systems and causes them to wake up from sleep prematurely. For this reason, make the code in question clear the status of all ACPI events when entering all sleep states (in addition to S5) to avoid the premature wakeups (this may cause some wakeup events to be missed in theory, but the likelihood of that is small and the change here simply restores the previous behavior of the code).

2018-08-14PCI/MSI: Set IRQCHIP_ONESHOT_SAFE for PCI-MSI irqchipsHeiner Kallweit
If flag IRQCHIP_ONESHOT_SAFE isn't set for an irqchip and we have a threaded interrupt with no primary handler, flag IRQF_ONESHOT needs to be set for the interrupt, causing some overhead in the threaded interrupt handler. For more detailed explanation also check following comment in __setup_irq(): The interrupt was requested with handler = NULL, so we use the default primary handler for it. But it does not have the oneshot flag set. In combination with level interrupts this is deadly, because the default primary handler just wakes the thread, then the irq lines is reenabled, but the device still has the level irq asserted. Rinse and repeat.... While this works for edge type interrupts, we play it safe and reject unconditionally because we can't say for sure which type this interrupt really has. The type flags are unreliable as the underlying chip implementation can override them. Another comment in __setup_irq() gives a hint already that this overhead can be avoided for PCI-MSI: Some irq chips like MSI based interrupts are per se one shot safe. Check the chip flags, so we can avoid the unmask dance at the end of the threaded handler for those. Following this let's mark all PCI-MSI irqchips as oneshot-safe.

2018-08-14PCI/VPD: Check for VPD access completion before checking for timeoutBert Kenward
Previously we checked the timeout before checking the VPD access completion bit. On a very heavily loaded system this can cause VPD access to timeout. Check the completion bit before checking the timeout. Signed-off-by: Bert Kenward <bkenward@solarflare.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2018-08-14rtc: isl1208: Add "evdet" interrupt source for isl1219Denis Osterland
Add support for "evdet" named interrupt source. The check if i2c client irq matches evdet irq is needed for the case that there is only one interrupt named "evdet". In this case i2c client code handles this like an unnamed interrupt souce and assigns the value.

2018-08-14PCI: Add PCI_DEVICE_DATA() macro to fully describe device ID entryAndy Shevchenko
There are a lot of examples in the kernel where PCI_VDEVICE() is used and still looks not so convenient due to additional driver_data field attached. Introduce PCI_DEVICE_DATA() macro to fully describe device ID entry in shortest possible form. For example, before: { PCI_VDEVICE(INTEL, PCI_DEVICE_ID_INTEL_MRFLD), (kernel_ulong_t) &dwc3_pci_mrfld_properties, }, after: { PCI_DEVICE_DATA(INTEL, MRFLD, &dwc3_pci_mrfld_properties) }, Drivers can be converted later on in independent way. While here, remove the unused macro with the same name from Ralink wireless driver.

2018-08-14rtc: isl1208: add support for isl1219 with tamper detectionMichael Grzeschik
We add support for the ISL1219 chip that got an integrated tamper detection function. This patch implements the feature by adding an additional timestamp0 file to sysfs device path. This file contains seconds since epoch, if an event occurred, or is empty, if none occurred.

This patches addresses following problem: rtc_allocate_device devm_device_add_group <-- kernel oops / null pointer, because sysfs entry does not yet exist rtc_register_device rc = devm_device_add_group if (rc) return rc; <-- forbidden to return error code after device register This patch adds rtc_add_group(s) functions.

2018-08-14ALSA: seq: virmidi: Fix discarding the unsubscribed outputTakashi Iwai
The recent change to move the virmidi output processing to a work slightly modified the code to discard the unsubscribed outputs so that it works without a temporary buffer. However, this is actually buggy, and may spew a kernel warning due to the unexpected call of snd_rawmidi_transmit_ack(), as triggered by syzbot. This patch takes back to the original code in that part, use a temporary buffer and simply repeat snd_rawmidi_transmit(), in order to address the regression.
