Pull tile update from Chris Metcalf: "The interesting bug fix is support for the upcoming "4.2" release of the Tilera hypervisor, which by default launches Linux at privilege level 2 instead of 1. The fix lets new and old hypervisors and Linuxes interoperate more smoothly, so I've tagged it for stable@kernel.org so that older Linuxes will be able to boot under the newer hypervisor." * 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: usb: tilegx: fix memleak when create hcd fail arch/tile: remove inline marking of EXPORT_SYMBOL functions rtc: rtc-tile: add missing platform_device_unregister() when module exit tile: support new Tilera hypervisor

The semctl GETNCNT returns the number of semops waiting for the specified semaphore to become nonzero. After commit 9f1bc2c9 ("ipc,sem: have only one list in struct sem_queue"), the semops waiting on just one semaphore are waiting on that semaphore's list. In order to return the correct count, we have to walk that list too, in addition to the sem_array's list for complex operations.

Pull btrfs update from Chris Mason: "These are mostly fixes. The biggest exceptions are Josef's skinny extents and Jan Schmidt's code to rebuild our quota indexes if they get out of sync (or you enable quotas on an existing filesystem). The skinny extents are off by default because they are a new variation on the extent allocation tree format. btrfstune -x enables them, and the new format makes the extent allocation tree about 30% smaller. I rebased this a few days ago to rework Dave Sterba's crc checks on the super block, but almost all of these go back to rc6, since I though 3.9 was due any minute. The biggest missing fix is the tracepoint bug that was hit late in 3.9. I ran into problems with that in overnight testing and I'm still tracking it down.

由 Guenter Roeck 提交于
A race condition exists when registering the first watchdog device. Sequence of events: - watchdog_register_device calls watchdog_dev_register - watchdog_dev_register creates the watchdog misc device by calling misc_register. At that time, the matching character device (/dev/watchdog0) does not yet exist, and old_wdd is not set either. - Userspace gets an event and opens /dev/watchdog - watchdog_open is called and sets wdd = old_wdd, which is still NULL, and tries to dereference it. This causes the kernel to panic. Seen with systemd trying to open /dev/watchdog immediately after it was created.

Commit 8a965b3b ("mm, slab_common: Fix bootstrap creation of kmalloc caches") introduced a regression that caused us to crash early during boot. The commit was introducing ordering of slab creation, making sure two odd-sized slabs were created after specific powers of two sizes. But, if any of the power of two slabs were created earlier during boot, slabs at index 1 or 2 might not get created at all. This patch makes sure none of the slabs get skipped. Tony Lindgren bisected this down to the offending commit, which really helped because bisect kept bringing me to almost but not quite this one.

Unlike meta data server mounts which support multiple mount points to the same server via struct nfs_server, data servers support a single connection. Concurrent calls to setup the data server connection can race where the first call allocates the nfs_client struct, and before the cache struct nfs_client pointer can be set, a second call also tries to setup the connection, finds the already allocated nfs_client, bumps the reference count, re-initializes the session,etc. This results in a hanging data server session after umount.

In case of error, the function ptp_clock_register() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

of_mdiobus_register creates a phy_device even if get_phy_device failed to create it previously. This causes indefinite polling on non-existent PHYs. This fix makes of_mdio_register rely on get_phy_device to properly create the device or fail otherwise.

The driver and firmware sync up through SYNC messages, and the firmware's affirmative reply to these SYNC messages appears to be the "Reset" indication received via the status interrupt endpoint. Thus the driver needs the status interrupt endpoint always active so that the Reset indication can be received even if the netdev is closed, which is the case right after device insertion. If the Reset indication is not received by the driver, it continues sending SYNC messages to the firmware, which crashes about 10 seconds later and the device stops responding.
