2015-10-31gpio / ACPI: Allow shared GPIO event to be read via operation regionMika Westerberg
In Microsoft Surface3 the GPIO detecting lid state is shared between GPIO event and operation region. Below is simplied version of the DSDT from Surface3 including relevant parts: Scope (GPO0) { Name (_AEI, ResourceTemplate () { GpioInt (Edge, ActiveBoth, Shared, PullNone, 0x0000, "\\_SB.GPO0", 0x00, ResourceConsumer, , ) { // Pin list 0x004C } }) OperationRegion (GPOR, GeneralPurposeIo, Zero, One) Field (GPOR, ByteAcc, NoLock, Preserve) { Connection ( GpioIo (Shared, PullNone, 0x0000, 0x0000, IoRestrictionNone, "\\_SB.GPO0", 0x00, ResourceConsumer,,) { // Pin list 0x004C } ), HELD, 1 } Method (_E4C, 0, Serialized) // _Exx: Edge-Triggered GPE { If ((HELD == One)) { ^^LID.LIDB = One } Else { ^^LID.LIDB = Zero Notify (LID, 0x80) // Status Change } Notify (^^PCI0.SPI1.NTRG, One) // Device Check } } When GPIO 0x4c changes we call ASL method _E4C which tries to read HELD field (the same GPIO). This triggers following error on the console: ACPI Error: Method parse/execution failed [\_SB.GPO0._E4C] (Node ffff88013f4b4438), AE_ERROR (20150930/psparse-542) The error happens because ACPI GPIO operation region handler (acpi_gpio_adr_space_handler()) tries to acquire the very same GPIO which returns an error (-EBUSY) because the GPIO is already reserved for the GPIO event. Fix this so that we "borrow" the event GPIO if we find the GPIO belongs to an event. Allow this only for GPIOs that are read. To be able to go through acpi_gpio->events list for operation region access we need to make sure the list is properly initialized whenever GPIO chip is registered.

2015-10-30mtd: blkdevs: fix potential deadlock + lockdep warningsBrian Norris
Commit 073db4a51ee4 ("mtd: fix: avoid race condition when accessing mtd->usecount") fixed a race condition but due to poor ordering of the mutex acquisition, introduced a potential deadlock. The deadlock can occur, for example, when rmmod'ing the m25p80 module, which will delete one or more MTDs, along with any corresponding mtdblock devices. This could potentially race with an acquisition of the block device as follows. -> blktrans_open() -> mutex_lock(&dev->lock); -> mutex_lock(&mtd_table_mutex); -> del_mtd_device() -> mutex_lock(&mtd_table_mutex); -> blktrans_notify_remove() -> del_mtd_blktrans_dev() -> mutex_lock(&dev->lock); This is a classic (potential) ABBA deadlock, which can be fixed by making the A->B ordering consistent everywhere. There was no real purpose to the ordering in the original patch, AFAIR, so this shouldn't be a problem. This ordering was actually already present in del_mtd_blktrans_dev(), for one, where the function tried to ensure that its caller already held mtd_table_mutex before it acquired &dev->lock: if (mutex_trylock(&mtd_table_mutex)) { mutex_unlock(&mtd_table_mutex); BUG(); } So, reverse the ordering of acquisition of &dev->lock and &mtd_table_mutex so we always acquire mtd_table_mutex first.

2015-10-31Revert "md: allow a partially recovered device to be hot-added to an array."NeilBrown
This reverts commit 7eb418851f3278de67126ea0c427641ab4792c57. This commit is poorly justified, I can find not discusison in email, and it clearly causes a problem. If a device which is being recovered fails and is subsequently re-added to an array, there could easily have been changes to the array *before* the point where the recovery was up to. So the recovery must start again from the beginning. If a spare is being recovered and fails, then when it is re-added we really should do a bitmap-based recovery up to the recovery-offset, and then a full recovery from there. Before this reversion, we only did the "full recovery from there" which is not corect. After this reversion with will do a full recovery from the start, which is safer but not ideal. It will be left to a future patch to arrange the two different styles of recovery.

2015-10-31md/raid5: fix locking in handle_stripe_clean_event()Roman Gushchin
After commit 566c09c53455 ("raid5: relieve lock contention in get_active_stripe()") __find_stripe() is called under conf->hash_locks + hash. But handle_stripe_clean_event() calls remove_hash() under conf->device_lock. Under some cirscumstances the hash chain can be circuited, and we get an infinite loop with disabled interrupts and locked hash lock in __find_stripe(). This leads to hard lockup on multiple CPUs and following system crash. I was able to reproduce this behavior on raid6 over 6 ssd disks. The devices_handle_discard_safely option should be set to enable trim support. The following script was used: for i in `seq 1 32`; do dd if=/dev/zero of=large$i bs=10M count=100 & done neilb: original was against a 3.x kernel. I forward-ported to 4.3-rc. This verison is suitable for any kernel since Commit: 59fc630b8b5f ("RAID5: batch adjacent full stripe write") (v4.1+). I'll post a version for earlier kernels to stable.

2015-10-30PCI: Fix sriov_enable() error path for pcibios_enable_sriov() failuresAlexander Duyck
Disable VFs if pcibios_enable_sriov() fails, just like we do for other errors in sriov_enable(). Call pcibios_sriov_disable() if virtfn_add() fails.

2015-10-30PCI: Wait 1 second between disabling VFs and clearing NumVFsAlexander Duyck
Per sec 3.3.3.1 of the SR-IOV spec, r1.1, we must allow 1.0s after clearing VF Enable before reading any field in the SR-IOV Extended Capability. Wait 1 second before calling pci_iov_set_numvfs(), which reads PCI_SRIOV_VF_OFFSET and PCI_SRIOV_VF_STRIDE after it sets PCI_SRIOV_NUM_VF.

If virtfn_add() fails, we call virtfn_remove() for any previously added devices. Remove the devices in reverse order (first-added is last-removed), which is more natural and doesn't require an additional variable.

2015-10-30mfd: sec-core: Remove unused s2mpu02-rtc and s2mpu02-clk childrenKrzysztof Kozlowski
The commit 54e8827d5f0e ("mfd: sec-core: Add support for S2MPU02 device") added new MFD child devices for S2MPU02: RTC and clock provider (the clock provider with new compatible). However support for these devices was not added to existing drivers (rtc-s5m, clk-s2mps11). New drivers were not submitted neither. This means that the name of children devices is completely unused. The "samsung,s2mpu02-clk" compatible remains undocumented so it is unclear what is provided by that compatible. Clean up this by removing unused child devices and undocumented compatible.

2015-10-30rbd: require stable pages if message data CRCs are enabledRonny Hegewald
rbd requires stable pages, as it performs a crc of the page data before they are send to the OSDs. But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0 "mm: only enforce stable page writes if the backing device requires it") it is not assumed anymore that block devices require stable pages. This patch sets the necessary flag to get stable pages back for rbd. In a ceph installation that provides multiple ext4 formatted rbd devices "bad crc" messages appeared regularly (ca 1 message every 1-2 minutes on every OSD that provided the data for the rbd) in the OSD-logs before this patch. After this patch this messages are pretty much gone (only ca 1-2 / month / OSD).

The irq handler should be registered after the tempmon module has been initialized in a known state and the thermal_zone and cpu_cooling device have been registered successfully. Otherwise, if the irq is triggled earlier before thermal probe has been finished, it may lead to 'NULL' pointer kernel panic.

2015-10-30thermal: rockchip: fix handling of invalid readingsDmitry Torokhov
We attempted to signal invalid code by returning -EAGAIN from rk_tsadcv2_code_to_temp(), unfortunately the return value was stuffed directly into the temperature pointer, potentially confusing upper layers with temperature of -EINVAL. Let's split temperature from error/success indicator to avoid such confusion. Also change the way we scan the temperature table to start with the 2nd element so that we do not need to worry that we may reference out of bounds element while doing binary search and keep checking that we end up with 'mid' equal to 0 (since we are looking for the temperature that would fall into interval between the 'mid' and 'mid - 1') .
