I am still seeing the above 2 warnings and also now:
vmlinux.o: warning: objtool: xen_get_debugreg()+0xb: call to HYPERVISOR_get_debugreg() leaves .noinstr.text section
vmlinux.o: warning: objtool: xen_set_debugreg()+0x15: call to HYPERVISOR_set_debugreg.isra.0() leaves .noinstr.text section
Presumably caused by
f4afb713e5c3 ("x86/xen: Make get_debugreg() noinstr")
7361fac0465b ("x86/xen: Make set_debugreg() noinstr")
