To avoid duplication of these headers, asm-generic is introduced. With the following patch, an architecture uses generic headers mentioned in the file arch/$(ARCH)/include/asm/Makefile To use a generic header is needed to add to arch/$(ARCH)/include/asm/Makefile : generic-y +=3D For each mentioned header in arch/$(ARCH)/include/asm/Makefile, the necessary wrapper in arch/$(ARCH)/include/generated/asm will be generated. As the base Makefile.asm-generic from Linux kernel was taken. ( 06c2afb862f9da8 "Linux 6.5-rc1" ).

Original asm/vm_event.h from ARM was updated: * use SPDX-License-Identifier. * update comment messages of stubs. * update #ifdef * instead of "include " -> "public/vm_event.h" As vm_event.h was moved to asm-generic then it is needed to create Makefile in arm/include/asm/ and add generated-y +=3D vm_event.h to it.
