2020-09-11T18:29:10Z

Besides disabling MMU, HVC_SOFT_RESTART also clears I+D bits. These behaviors are what kexec-reboot expects, so describe it more precisely.

KVM: arm64: Document PV-time interface

2019-10-21T18:20:25Z

Introduce a paravirtualization interface for KVM/arm64 based on the "Arm Paravirtualized Time for Arm-Base Systems" specification DEN 0057A. This only adds the details about "Stolen Time" as the details of "Live Physical Time" have not been fully agreed. User space can specify a reserved area of memory for the guest and inform KVM to populate the memory with information on time that the host kernel has stolen from the guest. A hypercall interface is provided for the guest to interrogate the hypervisor's support for this interface and the location of the shared memory structures.

Documentation: move Documentation/virtual to Documentation/virt

2019-07-24T08:52:11Z

Renaming docs seems to be en vogue at the moment, so fix on of the grossly misnamed directories. We usually never use "virtual" as a shortcut for virtualization in the kernel, but always virt, as seen in the virt/ top-level directory. Fix up the documentation to match that.
