[PATCH v5 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
