Merge tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull hmm updates from Jason Gunthorpe: "This series focuses on corner case bug fixes and general clarity improvements to hmm_range_fault(). It arose from a review of hmm_range_fault() by Christoph, Ralph and myself.
hmm_range_fault() is being used by these 'SVM' style drivers to non-destructively read the page tables. It is very similar to get_user_pages() except that the output is an array of PFNs and per-pfn flags, and it has various modes of reading.
This is necessary before RDMA ODP can be converted, as we don't want to have weird corner case regressions, which is still a looking forward item. Ralph has a nice tester for this routine, but it is waiting for feedback from the selftests maintainers.
Summary:
- 9 bug fixes
- Allow pgmap to track the 'owner' of a DEVICE_PRIVATE - in this case the owner tells the driver if it can understand the DEVICE_PRIVATE page or not. Use this to resolve a bug in nouveau where it could touch DEVICE_PRIVATE pages from other drivers.
- Remove a bunch of dead, redundant or unused code and flags
- Clarity improvements to hmm_range_fault()"

KVM: PPC: Book3S HV: Add a capability for enabling secure guests
At present, on Power systems with Protected Execution Facility hardware and an ultravisor, a KVM guest can transition to being a secure guest at will. Userspace (QEMU) has no way of knowing whether a host system is capable of running secure guests. This will present a problem in future when the ultravisor is capable of migrating secure guests from one host to another, because virtualization management software will have no way to ensure that secure guests only run in domains where all of the hosts can support secure guests.
This adds a VM capability which has two functions: (a) userspace can query it to find out whether the host can support secure guests, and (b) userspace can enable it for a guest, which allows that guest to become a secure guest. If userspace does not enable it, KVM will return an error when the ultravisor does the hypercall that indicates that the guest is starting to transition to a secure guest. The ultravisor will then abort the transition and the guest will terminate.

KVM: PPC: Book3S HV: H_SVM_INIT_START must call UV_RETURN
When the call to UV_REGISTER_MEM_SLOT is failing, for instance because there is not enough free secured memory, the Hypervisor (HV) has to call UV_RETURN to report the error to the Ultravisor (UV). Then the UV will call H_SVM_INIT_ABORT to abort the securing phase and go back to the calling VM.
If the kvm->arch.secure_guest is not set, in the return path rfid is called but there is no valid context to get back to the SVM since the Hcall has been routed by the Ultravisor.
Move the setting of kvm->arch.secure_guest earlier in kvmppc_h_svm_init_start() so in the return path, UV_RETURN will be called instead of rfid.

ARM: - cleanups and corner case fixes.
PPC: - Bugfixes
x86: - Support for mapping DAX areas with large nested page table entries.
- Cleanups and bugfixes here too. A particularly important one is a fix for FPU load when the thread has TIF_NEED_FPU_LOAD. There is also a race condition which could be used in guest userspace to exploit the guest kernel, for which the embargo expired today.
- Fast path for IPI delivery vmexits, shaving about 200 clock cycles from IPI latency.
- Protect against "Spectre-v1/L1TF" (bring data in the cache via speculative out of bound accesses, use L1TF on the sibling hyperthread to read it), which unfortunately is an even bigger whack-a-mole game than SpectreV1.
Sean continues his mission to rewrite KVM. In addition to a sizable number of x86 patches, this time he contributed a pretty large refactoring of vCPU creation that affects all architectures but should not have any visible effect.
s390 will come next week together with some more x86 patches"
