4.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Juergen Gross <jgr...@suse.com> commit 357d291ce035d1b757568058f3c9898c60d125b1 upstream. The boot loader version reported via sysfs is wrong in case of the kernel being booted via the Xen PVH boot entry. it should be 2.12 (0x020c), but it is reported to be 2.18 (0x0212). As the current way to set the version is error prone use the more readable variant (2 << 8) | 12.
