When we're about to run a vcpu, it is crucial that the redistributor associated with the physical CPU is being told about the new residency. This is abstracted by hijacking the irq_set_affinity method for the doorbell interrupt associated with the VPE. It is expected that the hypervisor will call this method before scheduling the VPE.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
