After these changes the new <linux/sched.h>'s typical preprocessed size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K lines), which is around 40% faster to build on typical configs. Not much changed from the last version (-v2) posted three weeks ago: I eliminated quirks, backmerged fixes plus I rebased it to an upstream SHA1 from yesterday that includes most changes queued up in -next plus all sched.h changes that were pending from Andrew. I've re-tested the series both on x86 and on cross-arch defconfigs, and did a bisectability test at a number of random points. I tried to test as many build configurations as possible, but some build breakage is probably still left - but it should be mostly limited to architectures that have no cross-compiler binaries available on kernel.org, and non-default configurations" * 'WIP.sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (146 commits) sched/headers: Clean up <linux/sched.h> sched/headers: Remove #ifdefs from <linux/sched.h> sched/headers: Remove the <linux/topology.h> include from <linux/sched.h> sched/headers, hrtimer: Remove the <linux/wait.h> include from <linux/hrtimer.h> sched/headers, x86/apic: Remove the <linux/pm.h> header inclusion from <asm/apic.h> sched/headers, timers: Remove the <linux/sysctl.h> include from <linux/timer.h> sched/headers: Remove <linux/magic.h> from <linux/sched/task_stack.h> sched/headers: Remove <linux/sched.h> from <linux/sched/init.h> sched/core: Remove unused prefetch_stack() sched/headers: Remove <linux/rculist.h> from <linux/sched.h> sched/headers: Remove the 'init_pid_ns' prototype from <linux/sched.h> sched/headers: Remove <linux/signal.h> from <linux/sched.h> sched/headers: Remove <linux/rwsem.h> from <linux/sched.h> sched/headers: Remove the runqueue_is_locked() prototype sched/headers: Remove <linux/sched.h> from <linux/sched/hotplug.h> sched/headers: Remove <linux/sched.h> from <linux/sched/debug.h> sched/headers: Remove <linux/sched.h> from <linux/sched/nohz.h> sched/headers: Remove <linux/sched.h> from <linux/sched/stat.h> sched/headers: Remove the <linux/gfp.h> include from <linux/sched.h> sched/headers: Remove <linux/rtmutex.h> from <linux/sched.h> ... 2017-03-02T23:16:38+00:00 Linus Torvalds torvalds@linux-foundation.org 2017-03-02T23:16:38+00:00 urn:sha1:69fd110eb650ea7baa82158f3b89a7d86da1d056 Pull vfs sendmsg updates from Al Viro: "More sendmsg work.

As this may be misleading let's refactor this function and avoid adding and removing ep0 to eplist and place it immediately in correct place. In addition let's remove redundant 0 assignments as ep array is zeroed during allocation.

It is stored separately in ep0 field. This causes an urb hang if gadget driver decides to delay setup handling. On host side this is visible as timeout error when setting configuration. This bug can be reproduced using for example any gadget with mass storage function.

Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far second (22.5%). The remaining 9.3% are scattered on gadget drivers. The most important changes for dwc2 are the peripheral side DMA support implemented by Synopsys folks and support for the new IOT dwc2 compatible core from Synopsys. In dwc3 land we have support for high-bandwidth, high-speed isochronous endpoints and some non-critical fixes for large scatter lists. Apart from these, we have our usual set of cleanups, non-critical fixes, etc.
