Re: [PATCH v4 2/2] xen: move arm/include/asm/vm_event.h to asm-generic

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

The change which adds generic-y += vm_event.h to ARM's Kbuild was lost during creation of the patch. Should be added in the next patch version

asm/vm_event.h is common for ARM and RISC-V so it will be moved to
asm-generic dir.

Original asm/vm_event.h from ARM was updated:
 * use SPDX-License-Identifier.
 * update comment messages of stubs.
 * update #ifdef.
 * change public/domctl.h to public/vm_event.h.
