The type 'enum kvm_reg_ex' is an extension of 'enum kvm_reg', however the extension is only semantical and the compiler doesn't know about the relationship between the two types. In kvm_pdptr_read() a value of the extended type is passed to kvm_x86_ops->cache_reg(), which expects a value of the base type. Clang raises the following warning about the type mismatch: arch/x86/kvm/kvm_cache_regs.h:44:32: warning: implicit conversion from enumeration type 'enum kvm_reg_ex' to different enumeration type 'enum kvm_reg' [-Wenum-conversion] kvm_x86_ops->cache_reg(vcpu, VCPU_EXREG_PDPTR); Cast VCPU_EXREG_PDPTR to 'enum kvm_reg' to make the compiler happy.

Devices which use level-triggered interrupts under Windows 2016 with Hyper-V role enabled don't work: Windows disables EOI broadcast in SPIV unconditionally. Our in-kernel IOAPIC implementation emulates an old IOAPIC version which has no EOI register so EOI never happens. The issue was discovered and discussed a while ago: https://www.spinics.net/lists/kvm/msg148098.html While this is a guest OS bug (it should check that IOAPIC has the required capabilities before disabling EOI broadcast) we can workaround it in KVM: advertising DIRECTED_EOI with in-kernel IOAPIC makes little sense anyway.

Add support for AMD Core Performance counters in the guest. The base event select and counter MSRs are changed. In addition, with the core extension, there are 2 extra counters available for performance measurements for a total of 6. With the new MSRs, the logic to map them to the gp_counters[] is changed. New functions are added to check the validity of the get/set MSRs. If the guest has the X86_FEATURE_PERFCTR_CORE cpuid flag set, the number of counters available to the vcpu is set to 6. It the flag is not set then it is 4.

This commit implements an enhanced x86 version of S390 KVM_CAP_SYNC_REGS functionality. KVM_CAP_SYNC_REGS "allow[s] userspace to access certain guest registers without having to call SET/GET_*REGS”. This reduces ioctl overhead which is particularly important when userspace is making synchronous guest state modifications (e.g. when emulating and/or intercepting instructions). Originally implemented upstream for the S390, the x86 differences follow: - userspace can select the register sets to be synchronized with kvm_run using bit-flags in the kvm_valid_registers and kvm_dirty_registers fields. - vcpu_events is available in addition to the regs and sregs register sets.

In Hyper-V, the fast guest->host notification mechanism is the SIGNAL_EVENT hypercall, with a single parameter of the connection ID to signal. Currently this hypercall incurs a user exit and requires the userspace to decode the parameters and trigger the notification of the potentially different I/O context. To avoid the costly user exit, process this hypercall and signal the corresponding eventfd in KVM, similar to ioeventfd. The association between the connection id and the eventfd is established via the newly introduced KVM_HYPERV_EVENTFD ioctl, and maintained in an (srcu-protected) IDR.

Re-enable deep flush so that users always have a way to be sure that a write makes it all the way out to media. Writes from the PMEM driver always arrive at the NVDIMM since movnt is used to bypass the cache, and the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to flush write buffers on power failure. The Deep Flush mechanism is there to explicitly write buffers to protect against (rare) ADR failure. This change prevents a regression in deep flush behavior so that applications can continue to depend on fsync() as a mechanism to trigger deep flush in the filesystem-DAX case.

Filesystem-DAX is incompatible with 'longterm' page pinning. Without page cache indirection a DAX mapping maps filesystem blocks directly. This means that the filesystem must not modify a file's block map while any page in a mapping is pinned. In order to prevent the situation of userspace holding of filesystem operations indefinitely, disallow 'longterm' Filesystem-DAX mappings. RDMA has the same conflict and the plan there is to add a 'with lease' mechanism to allow the kernel to notify userspace that the mapping is being torn down for block-map maintenance. Perhaps something similar can be put in place for vfio. Note that xfs and ext4 still report: "DAX enabled. Warning: EXPERIMENTAL, use at your own risk" ...at mount time, and resolving the dax-dma-vs-truncate problem is one of the last hurdles to remove that designation.

Pull power management fixes from Rafael Wysocki: "These fix three issues in cpufreq drivers: one recent regression, one leftover Kconfig dependency and one old but "stable" material. Specifics: - Make the task scheduler load and utilization signals be frequency-invariant again after recent changes in the SCPI cpufreq driver (Dietmar Eggemann). - Drop an unnecessary leftover Kconfig dependency from the SCPI cpufreq driver (Sudeep Holla). - Fix the initialization of the s3c24xx cpufreq driver (Viresh Kumar)" * tag 'pm-4.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: s3c24xx: Fix broken s3c_cpufreq_init() cpufreq: scpi: Fix incorrect arm_big_little config dependency cpufreq: scpi: invoke frequency-invariance setter function

When recursive inclusion is detected, the line number of the last 'included from:' is wrong. [Test Case] Kconfig: -------->8-------- source "Kconfig2" -------->8-------- Kconfig2: -------->8-------- source "Kconfig3" -------->8-------- Kconfig3: -------->8-------- source "Kconfig" -------->8-------- [Result] $ make allyesconfig scripts/kconfig/conf --allyesconfig Kconfig Kconfig:1: recursive inclusion detected. Inclusion path: current file : 'Kconfig' included from: 'Kconfig3:1' included from: 'Kconfig2:1' included from: 'Kconfig:3' scripts/kconfig/Makefile:89: recipe for target 'allyesconfig' failed make[1]: *** [allyesconfig] Error 1 Makefile:512: recipe for target 'allyesconfig' failed make: *** [allyesconfig] Error 2 where we expect current file : 'Kconfig' included from: 'Kconfig3:1' included from: 'Kconfig2:1' included from: 'Kconfig:1' The 'iter->lineno+1' in the second fpinrtf() should be 'iter->lineno-1'. I refactored the code to merge the two fprintf() calls. Signed-off-by: NMasahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: NUlf Magnusson <ulfalizer@gmail.com>
