This patch adds an .adjust_global scheduler callback function, which allows adjusting the global scheduler parameters (rather th= an just one domain=92s parameters).=A0 This patch supports the addition of an ARINC 653 scheduler (which will be submitted in a subsequent patch), and= was suggested by George Dunlap and Keir Fraser in response to an earlier patch (ref: [Xen-devel] [PATCH 1/1] Xen ARINC 653 scheduler).
