stable inclusion from stable-v5.10.225 commit 239b1cacceece336072a944b24ac1fcaac42de1d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAQOJ9 CVE: CVE-2024-45025
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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 <linux/align.h> inside the tools/ folder and include it where needed.
