This function is used by UDP encapsulation protocols in RX when crossing encapsulation boundary. If ip_summed is set to CHECKSUM_UNNECESSARY and encapsulation is not set, change to CHECKSUM_NONE since the checksum has not been validated within the encapsulation.

This new ioctl call allows the user to supply a buffer of varying size in which a tree search can store its results. This is much more flexible if you want to receive items which are larger than the current fixed buffer of 3992 bytes or if you want to fetch more items at once. Items larger than this buffer are for example some of the type EXTENT_CSUM.

There is a potential dead lock if a cpu event occurs during nvme probe since it registered with hot cpu notification. This fixes the race by having the module register with notification outside of probe rather than have each device register. The actual work is done in a scheduled work queue instead of in the notifier since assigning IO queues has the potential to block if the driver creates additional queues.

- I didn't remember correctly that the Hans de Goede's ACPI video
patches actually didn't flip the video.use_native_backlight
default, although we had discussed that and decided to do that.
Since I said we would do that in the previous PM+ACPI pull
request, make that change for real now.
- ACPI bus check notifications for PCI host bridges don't cause
the bus below the host bridge to be checked for changes as they
should because of a mistake in the ACPI-based PCI hotplug (ACPIPHP)
subsystem that forgets to add hotplug contexts to PCI host bridge
ACPI device objects. Create hotplug contexts for PCI host bridges
too as appropriate.
- Revert recent cpufreq commit related to the big.LITTLE cpufreq
driver that breaks arm64 builds.
- Fix for a regression in the ppc-corenet cpufreq driver introduced
during the 3.15 cycle and causing the driver to use the remainder
from do_div instead of the quotient. From Ed Swarthout.
- Resets triggered by panic activate a BUG_ON() in vmalloc.c on
systems where the ACPI reset register is located in memory address
space. Fix from Randy Wright.
- Fix for a problem with cpufreq governors that decisions made by
them may be suboptimal due to the fact that deferrable timers are
used by them for CPU load sampling. From Srivatsa S Bhat.
- Fix for a problem with the Tegra cpufreq driver where the CPU
frequency is temporarily switched to a "stable" level that
is different from both the initial and target frequencies
during transitions which causes udelay() to expire earlier than
it should sometimes. From Viresh Kumar.
- New trace points and rework of some existing trace points for
system suspend/resume profiling from Todd Brandt.
- Assorted cpufreq fixes and cleanups from Stratos Karafotis and

Cancel the optimization of compiler for struct snd_compr_avail which size will be 0x1c in 32bit kernel while 0x20 in 64bit kernel under the optimizer.

The DRR scheduler requires that items on the active list are work
conserving, i.e. do not hold on to skbs for throttling purposes, etc.
Attaching e.g. tbf renders DRR useless because all other classes on the
active list are delayed as well.
So, warn users that this configuration won't work as expected; we
already do this in couple of other qdiscs, see e.g.

In skb_checksum complete, if we need to compute the checksum for the packet (via skb_checksum) save the result as CHECKSUM_COMPLETE. Subsequent checksum verification can use this. Also, added csum_complete_sw flag to distinguish between software and hardware generated checksum complete, we should always be able to trust the software computation.

Currently when the first checksum in a packet is validated using CHECKSUM_COMPLETE, ip_summed is overwritten to be CHECKSUM_UNNECESSARY so that any subsequent checksums in the packet are not correctly validated. This patch adds csum_valid flag in sk_buff and uses that to indicate validated checksum instead of setting CHECKSUM_UNNECESSARY. The bit is set accordingly in the skb_checksum_validate_* functions. The flag is checked in skb_checksum_complete, so that validation is communicated between checksum_init and checksum_complete sequence in TCP and UDP.

There are several instances where a pskb_copy or __pskb_copy is immediately followed by an skb_clone. Add a couple of new functions to allow the copy skb to be allocated from the fclone cache and thus speed up subsequent skb_clone calls.

This function sets the n'th cpu - local cpu's first. For example: in a 16 cores server with even cpu's local, will get the following values: cpumask_set_cpu_local_first(0, numa, cpumask) => cpu 0 is set cpumask_set_cpu_local_first(1, numa, cpumask) => cpu 2 is set ... cpumask_set_cpu_local_first(7, numa, cpumask) => cpu 14 is set cpumask_set_cpu_local_first(8, numa, cpumask) => cpu 1 is set cpumask_set_cpu_local_first(9, numa, cpumask) => cpu 3 is set ... cpumask_set_cpu_local_first(15, numa, cpumask) => cpu 15 is set Curently this function will be used by multi queue networking devices to calculate the irq affinity mask, such that as many local cpu's as possible will be utilized to handle the mq device irq's.

The majority of these changes are cleanups and fixes across all drivers. Redundant error messages are removed and more PWM controllers set the .can_sleep flag to signal that they can't be used in atomic context. Support is added for the Broadcom Kona family of SoCs and the Intel LPSS driver can now probe PCI devices in addition to ACPI devices. Upon shut- down, the pwm-backlight driver will now power off the backlight. It also uses the new descriptor-based GPIO API for more concise GPIO handling. A large chunk of these changes also converts platforms to use the lookup mechanism rather than relying on the global number space to reference PWM devices. This is largely in preparation for more unification and cleanups in future patches. Eventually it will allow the legacy PWM API to be removed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJTl/AqAAoJEN0jrNd/PrOhoZsP/1yLaSK3NuBXWg3VdpH9i8so GXBeh3dbKAmC5MYQlhh5XTvuNBbfOoSp6dGdL3pV9GjcffbqzTynn5YszrbanezX +fqBF1NvW+jb2sUfQmedh9y30O1ADZM0p+FXW/R7e2khiE+8VF2ox35Hc3LLBqk8 SiZoy1UEzIo0BAHgtgCw2VXUYUSYX/KYGoF/t8TCCObKVC3wQ7pW5tN3Ekj14yNL NspM0Q8OsITCQO0PdOfHw1gBmy4iLSuoNpPKP12BQVx5seZ4LBaIz9Wh0jFu89hq zI1gFpGptMsxsaAn/zk6Nr9lHDkqxkhnuYA+dgkA6k0KI9jS1Me20WQEmvM9H9xs BJ8QOfMQP7AHCZeW61J+iPTtCyMwFejRSPMtPjNMfaOQduWJw7+o0GaA30F39dw0 3Cki1C44o9KfwCdC9OcmLignHt5TC1FEJgJL4OY695x0za7XcVgEN6nTg70AQfaz pcm4PeCqtM9jvXdJQdDGDI7gVzT33kpBnGatqQ2bUqMDx8HeHIkdEXehLwsYP46m FX0RJb5ue40esbVWZDGYWJqkdInpHt6deahTW+Jq9Exo4ZMr5/DVkMQCl8oF3/em Y5ED67dnAQ4au1MhElnDTPKk4Uh28aWTYwo8HSO6rt+8jcguH1KvXvLa+z2BcaMv ZVN0ZPy2813ix6Q0yO3D =BDxR -----END PGP SIGNATURE----- Merge tag 'pwm/for-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm changes from Thierry Reding: "The majority of these changes are cleanups and fixes across all drivers.
