The following commit has been merged into the x86/apic branch of tip: Commit-ID: 9b09927c0cdec4d4e75f7f9e621eaec179a888fd Gitweb: https://git.kernel.org/tip/9b09927c0cdec4d4e75f7f9e621eaec179a888fd Author: Andy Shevchenko <andriy.shevchenko@linux.intel.com> AuthorDate: Thu, 24 Nov 2022 20:48:24 +02:00 Committer: Thomas Gleixner <tglx@linutronix.de> CommitterDate: Fri, 02 Dec 2022 14:57:13 +01:00 x86/of: Remove unused early_init_dt_add_memory_arch() Recently objtool started complaining about dead code in the object files, in particular vmlinux.o: warning: objtool: early_init_dt_scan_memory+0x191: unreachable instruction when CONFIG_OF=y. Indeed, early_init_dt_scan() is not used on x86 and making it compile (with help of CONFIG_OF) will abrupt the code flow since in the middle of it there is a BUG() instruction. Remove the pointless function.
