From 231429875bc01ca68660411ad61edff42c5cf36d Mon Sep 17 00:00:00 2001 From: Alexander Lobakin Date: Wed, 25 Sep 2024 10:47:47 +0800 Subject: [PATCH] tools: move alignment-related macros to new stable inclusion from stable-v6.6.48 commit a2081b8cabbead2393f3c27232f87ebc14bd70ff bugzilla: https://gitee.com/openeuler/kernel/issues/IAP55A Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=a2081b8cabbead2393f3c27232f87ebc14bd70ff -------------------------------- commit 10a04ff09bcc39e0044190ffe9f00f998f13647c upstream. Currently, tools have *ALIGN*() macros scattered across the unrelated headers, as there are only 3 of them and they were added separately each time on an as-needed basis. Anyway, let's make it more consistent with the kernel headers and allow using those macros outside of the mentioned headers. Create inside the tools/ folder and include it where needed.
