You need to prevent that breakage upfront not after the fact. Yes, I have considered to prevent that breakage in the patchset. Actually, Until the 11th patch, we put the intr_mode_init ahead of time, which will break XEN. Before the 11th patch, we just unify the code and do the preparation, Kernel will do the intr_mode_init like before, which will have no influence on XEN. So we put the patch here before 11th patch. Thanks, dou. Thanks, tglx _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
