I notice that sysenter_entry is not present in /proc/kallsyms for Xen kernels, but is present in my non-Xen FC5 kernel. I''m doing some security research and trying to install an LKM rootkit into a paravirtualized VM, but it''s trying to look up sysenter_entry during compile and failing. Can anyone explain why sysenter_entry is missing from the table, keeping in mind I''m a kernel neophyte?
