From 5e34bd1d548d440015d5bee3326e9d74cdebecd6 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 5 Dec 2018 16:37:53 +0900 Subject: kbuild: remove a special handling for *.agh in Makefile.headersinst scripts/Makefile.headersinst takes care of *.agh just for arch/cris/include/uapi/arch-v10/arch/sv_addr.agh because renaming exported headers is difficult (or impossible). This code is no longer necessary thanks to commit c690eddc2f3b ("CRIS: Drop support for the CRIS port").

(https://lkml.org/lkml/2017/7/10/121) I tweaked the meaning of mandatory-y a little bit; now it defines the minimum set of ASM headers that all architectures must have. If arch does not have specific implementation of a mandatory header, Kbuild will let it fallback to the asm-generic one by automatically generating a wrapper. This will allow to drop lots of redundant generic-y defines. Previously, "mandatory" was used in the context of UAPI, but I guess this can be extended to kernel space ASM headers.
