Here you go:
(XEN) Xen call trace:
(XEN) [<0000020000218568>] rangeset_remove_range+0xbc/0x2cc (PC)
(XEN) [<00000200002c76bc>] domain_build.c#make_hypervisor_node+0x294/0x7c4
(LR)
(XEN) [<00000200002ca240>] domain_build.c#handle_node+0x7ec/0x924
(XEN) [<00000200002ca7ac>] domain_build.c#construct_dom0+0x434/0x4d8
Can you append this to the commit msg while committing or do you want a respin?
