A number of further possible improvements were identified when putting
together the patches for these XSAs; some therefore already have acks or
alike. Some of these may want considering to take for 4.22.
Many of the patches here are largely independent, but the last one
(following on to XSA-491, while all others are XSA-492 related) really
depends on the 2nd to last one. Or else bigger changes would be
necessary there.
1: sched: introduce specialization of "running only" vcpu_runstate_get()
2: domctl: move XEN_DOMCTL_irq_permission handling to x86 code
3: domctl: rename a label
4: domctl: error code adjustment for unpriv callers
5: domctl/XSM: avoid XSM_OTHER with xsm_domctl()
6: domctl: handle XEN_DOMCTL_getvcpuinfo without acquiring domctl lock
7: domctl: restrict permission check for XEN_DOMCTL_memory_mapping's remove form
8: x86/domctl: don't imply I/O port permissions from I/O port mapping
9: x86/HVM: more checking for XEN_DOMCTL_ioport_mapping
