2017-06-04KVM: improve arch vcpu request definingAndrew Jones
Marc Zyngier suggested that we define the arch specific VCPU request base, rather than requiring each arch to remember to start from 8. That suggestion, along with Radim Krcmar's recent VCPU request flag addition, snowballed into defining something of an arch VCPU request defining API. No functional change. (Looks like x86 is running out of arch VCPU request bits. Maybe someday we'll need to extend to 64.)

2017-06-04posix-timers: Move interval out of the unionThomas Gleixner
Preparatory patch to unify the alarm timer and hrtimer based posix interval timer handling.

2017-06-04posix-clocks: Remove interval timer facility and mmap/fasync callbacksThomas Gleixner
The only user of this facility is ptp_clock, which does not implement any of those functions. Remove them to prevent accidental users. Especially the interval timer interfaces are now more or less impossible to implement because the necessary infrastructure has been confined to the core code. Aside of that it's really complex to make these callbacks implemented according to spec as the alarm timer implementation demonstrates. If at all then a nanosleep callback might be a reasonable extension. For now keep just what ptp_clock needs.

2017-06-04genirq: Handle NOAUTOEN interrupt setup properThomas Gleixner
If an interrupt is marked NOAUTOEN then request_irq() installs the action, but does not enable the interrupt via startup_irq(). The interrupt is enabled via enable_irq() later from the driver. enable_irq() calls irq_enable(). That means that for interrupts which have a irq_startup() callback this callback is never invoked. Neither is irq_domain_activate_irq() invoked for such interrupts. If an interrupt depends on irq_startup() or irq_domain_activate_irq() then the enable via irq_enable() is not enough. Add a status flag IRQD_IRQ_STARTED_UP and use this to select the proper mechanism in enable_irq(). Use the flag also to avoid pointless calls into the low level functions.

2017-06-03mux: minimal mux subsystemPeter Rosin
Add a new minimalistic subsystem that handles multiplexer controllers. When multiplexers are used in various places in the kernel, and the same multiplexer controller can be used for several independent things, there should be one place to implement support for said multiplexer controller. A single multiplexer controller can also be used to control several parallel multiplexers, that are in turn used by different subsystems in the kernel, leading to a need to coordinate multiplexer accesses. The multiplexer subsystem handles this coordination.

In this particular case we've had Reserving 4096MB of memory at 128MB for crashkernel (System RAM: 51200MB) so the low 2GB is mostly depleted. Fix this by considering memblock allocations in the initial static initialization estimation. Move the max_initialise to reset_deferred_meminit and implement a simple memblock_reserved_memory helper which iterates all reserved blocks and sums the size of all that start below the given address. The cumulative size is than added on top of the initial estimation. This is still not ideal because reset_deferred_meminit doesn't consider holes and so reservation might be above the initial estimation whihch we ignore but let's make the logic simpler until we really need to handle more complicated cases.

2017-06-02mm/hugetlb: report -EHWPOISON not -EFAULT when FOLL_HWPOISON is specifiedJames Morse
KVM uses get_user_pages() to resolve its stage2 faults. KVM sets the FOLL_HWPOISON flag causing faultin_page() to return -EHWPOISON when it finds a VM_FAULT_HWPOISON. KVM handles these hwpoison pages as a special case. (check_user_page_hwpoison()) When huge pages are involved, this doesn't work so well. get_user_pages() calls follow_hugetlb_page(), which stops early if it receives VM_FAULT_HWPOISON from hugetlb_fault(), eventually returning -EFAULT to the caller. The step to map this to -EHWPOISON based on the FOLL_ flags is missing. The hwpoison special case is skipped, and -EFAULT is returned to user-space, causing Qemu or kvmtool to exit. Instead, move this VM_FAULT_ to errno mapping code into a header file and use it from faultin_page() and follow_hugetlb_page(). With this, KVM works as expected. This isn't a problem for arm64 today as we haven't enabled MEMORY_FAILURE, but I can't see any reason this doesn't happen on x86 too, so I think this should be a fix. This doesn't apply earlier than stable's v4.11.1 due to all sorts of cleanup. [james.morse@arm.com: add vm_fault_to_errno() call to faultin_page()] suggested.

2017-06-02usb: gadget: Allow a non-SuperSpeed gadget to support LPMJohn Youn
This commit allows a gadget that does not support SuperSpeed to indicate that it supports LPM. It does this by setting the 'lpm_capable' flag in the gadget structure. If a gadget sets this, the composite gadget framework will set the bcdUSB to 0x0201 to indicate that this supports BOS descriptors, and also return a USB 2.0 Extension descriptor as part of the BOS descriptor set.

2017-06-01i40e/virtchnl: move function to virtchnlJesse Brandeburg
This moves a function that is needed for the virtchnl interface from the i40e PF driver over to the virtchnl.h file. It was manually verified that the function in question is unchanged except for the function name and function header, which explains the slight difference in the number of lines removed/added.

It also expands comments, and adds details on the usage of certain fields. In addition, due to the changes a couple of casts are needed to prevent errors found by sparse after renaming some fields.

2017-06-01virtchnl: rename i40e to generic virtchnlJesse Brandeburg
This morphs all the i40e and i40evf references to/in virtchnl.h to be generic, using only automated methods. Updates all the callers to use the new names. A followup patch provides separate clean ups for messy line conversions from these "automatic" changes, to make them more reviewable.

2017-06-01i40e/i40evf: create and use new unified header fileJesse Brandeburg
This moves a header for i40evf to include/linux/avf/virtchnl.h. The directory name AVF is an acronym for the Intel(R) Adaptive Virtual Function. This first step creates the new file, which is a rename of drivers/net/ethernet/intel/i40evf/i40e_virtchnl.h to include/linux/avf/virtchnl.h, and should show up in git as a rename when using git log --follow. To keep things building after the move, the changes to the i40evf driver are made to point to the new include file location.
