[Xen-devel] Sanity check input and serialize vcpu data in sched_rt.c

[Meng Xu <mengxu@xxxxxxxxxxxxx>]

These two patches are to solve the issues found by Jan Beulich at 
http://lists.xen.org/archives/html/xen-devel/2014-09/msg03554.html.

The solution is summarized by Dario Faggioli at 
http://lists.xen.org/archives/html/xen-devel/2014-09/msg03603.html.

Here is the solution:
     - sanity checking input params in rt_dom_cntl()
     - serialize rt_dom_cntl() itself against the global lock
     - move the call to rt_update_deadline() from _alloc to _insert
