Hi all,I'm trying ot figure out what that's all about? I see in 64 PV domU, it's being checked prior to returning from syscall. On the xen side, I see it tied to supervisor_mode_kernel, but the only info I find is changelog comment which suggests it's purpose is to allow dom0 run in ring 0... So why the check in a domU kernel? Thanks, Mukesh | | | | <= Invisible ribbon campain against overuse of macros :). | | _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
