While this is caused by a change in the Linux kernel, this only breaks running as a Xen guest because only Xen seems to emulate non-paging mode in a way that uses identity-mapped paging. On bare-metal the SMEP bit has no effect while the CPU is not in paging-mode. So I would not expect upstream to make any changes for that in Linux code.
