2016-12-14Remove references to dead make variable LINUX_INCLUDEPaul Bolle
Commit 4fd06960f120 ("Use the new x86 setup code for i386") introduced a reference to the make variable LINUX_INCLUDE. That reference got moved around a bit and copied twice and now there are three references to it. There has never been a definition of that variable. (Presumably that is because it started out as a mistyped reference to LINUXINCLUDE.) So this reference has always been an empty string. Let's remove it before it spreads any further.

2016-12-14x86/boot/64: Push correct start_cpu() return addressJosh Poimboeuf
start_cpu() pushes a text address on the stack so that stack traces from idle tasks will show start_cpu() at the end. But it currently shows the wrong function offset. It's more correct to show the address immediately after the 'lretq' instruction.

2016-12-13nvme/pci: Log PCI_STATUS when the controller diesAndy Lutomirski
When debugging nvme controller crashes, it's nice to know whether the controller died cleanly so that the failure is just reflected in CSTS, it died and put an error in PCI_STATUS, or whether it died so badly that it stopped responding to PCI configuration space reads.

2016-12-13block_dev: don't test bdev->bd_contains when it is not stableNeilBrown
bdev->bd_contains is not stable before calling __blkdev_get(). When __blkdev_get() is called on a parition with ->bd_openers == 0 it sets bdev->bd_contains = bdev; which is not correct for a partition. After a call to __blkdev_get() succeeds, ->bd_openers will be > 0 and then ->bd_contains is stable. When FMODE_EXCL is used, blkdev_get() calls bd_start_claiming() -> bd_prepare_to_claim() -> bd_may_claim() This call happens before __blkdev_get() is called, so ->bd_contains is not stable. So bd_may_claim() cannot safely use ->bd_contains. It currently tries to use it, and this can lead to a BUG_ON(). This happens when a whole device is already open with a bd_holder (in use by dm in my particular example) and two threads race to open a partition of that device for the first time, one opening with O_EXCL and one without. The thread that doesn't use O_EXCL gets through blkdev_get() to __blkdev_get(), gains the ->bd_mutex, and sets bdev->bd_contains = bdev; Immediately thereafter the other thread, using FMODE_EXCL, calls bd_start_claiming() from blkdev_get(). This should fail because the whole device has a holder, but because bdev->bd_contains == bdev bd_may_claim() incorrectly reports success. This thread continues and blocks on bd_mutex. The first thread then sets bdev->bd_contains correctly and drops the mutex. The thread using FMODE_EXCL then continues and when it calls bd_may_claim() again in: BUG_ON(!bd_may_claim(bdev, whole, holder)); The BUG_ON fires. Fix this by removing the dependency on ->bd_contains in bd_may_claim(). As bd_may_claim() has direct access to the whole device, it can simply test if the target bdev is the whole device.

2016-12-13Revert "nvme: add support for the Write Zeroes command"Linus Torvalds
This reverts commit 6d31e3ba232ea22458b2f36b6d3f2f9f11bf3fa4. This causes bootup problems for me both on my laptop and my desktop. What they have in common is that they have NVMe disks with dm-crypt, but it's not the same controller, so it's not controller-specific. Jens does not see it on his machine (also NVMe), so it's presumably something that triggers just on bootup. Possibly related to dm-crypt and the fact that I mark my luks volume with "allow-discards" in /etc/crypttab. It's 100% repeatable for me, which made it fairly straightforward to bisect the problem to this commit. Small mercies. So we don't know what the reason is yet, but the revert is needed to get things going again.

Commit 4efca4ed ("kbuild: modversions for EXPORT_SYMBOL() for asm") adds modversion support for symbols exported from asm files. Architectures must include C-style declarations for those symbols in asm/asm-prototypes.h in order for them to be versioned. Add these declarations for x86, and an architecture-independent file that can be used for common symbols. With f27c2f6 reverting 8ab2ae6 ("default exported asm symbols to zero") we produce a scary warning on x86, this commit fixes that.

It makes libata skip probing for NCQ prio unless the feature is explicitly requested by the user. This is necessary because some controllers lock up after the optional feature is probed" * 'for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: ata: avoid probing NCQ Prio Support if not explicitly requested
2016-12-13ata: avoid probing NCQ Prio Support if not explicitly requestedAdam Manzanares
Previously, when the ata device was being initialized we were probing for NCQ prio support by checking the identify information and also checking the log page that holds information about ncq prio support. This caused an error on an Intel HBA so the code is now updated to only probe for NCQ prio support when the sysfs variable controlling NCQ prio support is enabled. tj: Update formatting, switch to spin_[un]lock_irq() and update locking a bit, use REVALIDATE instead of RESET, and return -EIO instead of -EINVAL on config failure.

Dan Williams proposed a solution to force-switch the mode but deemed too hackishd. People are gonna discuss the proper way to handle the situation in nvme standard meetings. For now, detect and warn about the situation. - Low level driver specific changes. Christoph Hellwig pipes in about the hidden nvme warning: "I wish that was the case. We've pretty much agreed that we'll want to implement it as a virtual PCIe root bridge, similar to Intels other 'innovation' VMD that we work around that way. But Intel management has apparently decided that they don't want to spend more cycles on this now that Lenovo has an optional BIOS that doesn't force this broken mode anymore, and no one outside of Intel has enough information to implement something like this. So for now I guess this warning is it, until Intel reconsideres and spends resources on fixing up the damage their Chipset people caused" * 'for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: ahci: warn about remapped NVMe devices ahci-remap.h: add ahci remapping definitions nvme: move NVMe class code to pci_ids.h pata: imx: support controller modes up to PIO4 pata: imx: add support of setting timings for PIO modes pata: imx: set controller PIO mode with .set_piomode callback pata: imx: sort headers out ata: set ncq_prio_enabled iff device has support ata: ATA Command Priority Disabled By Default ata: Enabling ATA Command Priorities block: Add iocontext priority to request ahci: qoriq: added ls1046a platform support

2016-12-13dm flakey: introduce "error_writes" featureMike Snitzer
Recent dm-flakey fixes, to have reads error out during the "down" interval, made it so that the previous read behaviour is no longer available. It is useful to have reads complete like normal but have writes error out, so make it possible again with a new "error_writes" feature. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
