As per e23738a7 ("sched, inotify: Deal with nested sleeps"). fanotify_read is a wait loop with sleeps in. Wait loops rely on task_struct::state and sleeps do too, since that's the only means of actually sleeping. Therefore the nested sleeps destroy the wait loop state and the wait loop breaks the sleep functions that assume TASK_RUNNING (mutex_lock). Fix this by using the new woken_wake_function and wait_woken() stuff, which registers wakeups in wait and thereby allows shrinking the task_state::state changes to the actual sleep part.

When allocating space for load_balance_mask, in sched_init, when CPUMASK_OFFSTACK is set, we've managed to spill over KMALLOC_MAX_SIZE on our 6144 core machine. The patch below breaks up the allocations so that they don't overflow the max alloc size. It also allocates the masks on the the node from which they'll most commonly be accessed, to minimize remote accesses on NUMA machines.

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger: "kernel: Provide READ_ONCE and ASSIGN_ONCE As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com ACCESS_ONCE might fail with specific compilers for non-scalar accesses. Here is a set of patches to tackle that problem. The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types.

strcmp was lost when all other string functions were removed, but we still have an optimized version for this on CRISv32, so any driver built as a module would not have access to this symbol. In a similar manner, we had optimized versions of csum_partial_copy_from_user and __do_clear_user but no exported symbols for them, breaking bunch of other drivers when built as a module. At the same time, move EXPORT_SYMBOL(__copy_user) and EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's located together with the function definition.

Pull x86 apic updates from Thomas Gleixner: "After stopping the full x86/apic branch, I took some time to go through the first block of patches again, which are mostly cleanups and preparatory work for the irqdomain conversion and ioapic hotplug support. Unfortunaly one of the real problematic commits was right at the beginning, so I rebased this portion of the pending patches without the offenders. It would be great to get this into 3.19. That makes reworking the problematic parts simpler. The usual tip testing did not unearth any issues and it is fully bisectible now. I'm pretty confident that this wont affect the calmness of the xmas season. Changes: - Split the convoluted io_apic.c code into domain specific parts (vector, ioapic, msi, htirq) - Introduce proper helper functions to retrieve irq specific data instead of open coded dereferencing of pointers - Preparatory work for ioapic hotplug and irqdomain conversion - Removal of the non functional pci-ioapic driver - Removal of unused irq entry stubs - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC allocations for everything which is called from there. - Small cleanups and fixes" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) iommu/amd: Use helpers to access irq_cfg data structure associated with IRQ iommu/vt-d: Use helpers to access irq_cfg data structure associated with IRQ x86: irq_remapping: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Make MSI and HT_IRQ indepenent of X86_IO_APIC x86, irq: Move IRQ initialization routines from io_apic.c into vector.c x86, irq: Move IOAPIC related declarations from hw_irq.h into io_apic.h x86, irq: Move HT IRQ related code from io_apic.c into htirq.c x86, irq: Move PCI MSI related code from io_apic.c into msi.c x86, irq: Replace printk(KERN_LVL) with pr_lvl() utilities x86, irq: Make UP version of irq_complete_move() an inline stub x86, irq: Move local APIC related code from io_apic.c into vector.c x86, irq: Introduce helpers to access struct irq_cfg x86, irq: Protect __clear_irq_vector() with vector_lock x86, irq: Rename local APIC related functions in io_apic.c as apic_xxx() x86, irq: Refine hw_irq.h to prepare for irqdomain support x86, irq: Convert irq_2_pin list to generic list x86, irq: Kill useless parameter 'irq_attr' of IO_APIC_get_PCI_irq_vector() x86, irq, acpi: Get rid of special handling of GSI for ACPI SCI x86, irq: Introduce helper to check whether an IOAPIC has been registered ...
