Commit 074037ec (PM / Wakeup: Introduce wakeup source objects and event statistics (v3)) caused ACPI wakeup to only work if CONFIG_PM_SLEEP is set, but it also worked for CONFIG_PM_SLEEP unset before. This can be fixed by making device_set_wakeup_enable(), device_init_wakeup() and device_may_wakeup() work in the same way as before commit 074037ec when CONFIG_PM_SLEEP is unset.

Michael Leun reported that running parallel opens on a fuse filesystem can trigger a "kernel BUG at mm/truncate.c:475" Gurudas Pai reported the same bug on NFS. The reason is, unmap_mapping_range() is not prepared for more than one concurrent invocation per inode. For example: thread1: going through a big range, stops in the middle of a vma and stores the restart address in vm_truncate_count. thread2: comes in with a small (e.g. single page) unmap request on the same vma, somewhere before restart_address, finds that the vma was already unmapped up to the restart address and happily returns without doing anything. Another scenario would be two big unmap requests, both having to restart the unmapping and each one setting vm_truncate_count to its own value. This could go on forever without any of them being able to finish. Truncate and hole punching already serialize with i_mutex. Other callers of unmap_mapping_range() do not, and it's difficult to get i_mutex protection for all callers. In particular ->d_revalidate(), which calls invalidate_inode_pages2_range() in fuse, may be called with or without i_mutex. This patch adds a new mutex to 'struct address_space' to prevent running multiple concurrent unmap_mapping_range() on the same mapping. [ We'll hopefully get rid of all this with the upcoming mm preemptibility series by Peter Zijlstra, the "mm: Remove i_mmap_mutex lockbreak" patch in particular.

Commit 8ee294cd converted serio subsystem event handling from using a dedicated thread to using common workqueue. Unfortunately, this regressed our boot times, due to the fact that serio jobs take long time to execute. While the new concurrency managed workqueue code manages long-playing works just fine and schedules additional workers as needed, such works wreck havoc among remaining users of flush_scheduled_work(). To solve this problem let's move serio/gameport works from system_wq to system_long_wq which nobody tries to flush.

This errata occurs when the ARDY interrupt generation is enabled. At the begining of every new transaction the ARDY interrupt is cleared. On continuous i2c transactions where after clearing the ARDY bit from I2C_STAT register (clearing the interrupt), the IRQ line is reasserted and the I2C_STAT[ARDY] bit set again on 1. In fact, the ARDY status bit is not cleared at the write access to I2C_STAT[ARDY] and only the IRQ line is deasserted and then reasserted. This is not captured in the usual errata documents. The workaround is to have a double clear of ARDY status in irq handler.

When runtime PM is enabled, each OMAP i2c device is suspended after each i2c xfer. However, there are two cases when the static suspend methods must be used to ensure the devices are suspended: 1) runtime PM is disabled, either at compile time or dynamically via /sys/devices/.../power/control. 2) an i2c client driver uses i2c during it's suspend callback, thus leaving the i2c driver active (NOTE: runtime suspend transitions are disabled during system suspend, so i2c activity during system suspend will runtime resume the device, but not runtime (re)suspend it.) Since the actual work to suspend the device is handled by the subsytem, call the bus methods to take care of it. NOTE: This takes care of a known suspend problem on OMAP3 where the TWL RTC driver does i2c xfers during its suspend path leaving the i2c driver in an active state (since runtime suspend transistions are disabled.)

Right now we, are relying on the fact that when we attempt to actually do the discard, blkdev_issue_discar() returns -EOPNOTSUPP and the user is informed that the device does not support discard. However, in the case where the we do not hit any suitable free extent to trim in FITRIM code, it will finish without any error. This is very confusing, because it seems that FITRIM was successful even though the device does not actually supports discard.

This code path does not fill in the logsunit member of the passed xfs_fsop_geom_t, leading to the leaking of four bytes of uninitialized stack data to potentially unprivileged callers. v2 switches to memset() to avoid future issues if structure members change, on suggestion of Dave Chinner.

Currently the bridge multicast snooping feature periodically issues IPv6 general multicast listener queries to sense the absence of a listener. For this, it uses :: as its source address - however RFC 2710 requires: "To be valid, the Query message MUST come from a link-local IPv6 Source Address". Current Linux kernel versions seem to follow this requirement and ignore our bogus MLD queries. With this commit a link local address from the bridge interface is being used to issue the MLD query, resulting in other Linux devices which are multicast listeners in the network to respond with a MLD response (which was not the case before).

Map the IPv6 header's destination multicast address to an ethernet source address instead of the MLD queries multicast address. For instance for a general MLD query (multicast address in the MLD query set to ::), this would wrongly be mapped to 33:33:00:00:00:00, although an MLD queries destination MAC should always be 33:33:00:00:00:01 which matches the IPv6 header's multicast destination ff02::1.

Currently the multicast bridge snooping support is not active for link local multicast. I assume this has been done to leave important multicast data untouched, like IPv6 Neighborhood Discovery. In larger, bridged, local networks it could however be desirable to optimize for instance local multicast audio/video streaming too. With the transient flag in IPv6 multicast addresses we have an easy way to optimize such multimedia traffic without tempering with the high priority multicast data from well-known addresses. This patch alters the multicast bridge snooping for IPv6, to take effect for transient multicast addresses instead of non-link-local addresses.
