[PATCH v4 0/6] Support calling functions on dedicated physical cpu
Some hardware (e.g. Dell Studio laptops) require special functions to be called on physical cpu 0 in order to avoid occasional hangs. When running as dom0 under Xen this could be achieved only via special boot parameters (vcpu pinning) limiting the hypervisor in it's scheduling decisions. This patch series is adding a generic function to be able to temporarily pin a (virtual) cpu to a
