Date: Wed, 1 Jun 2022 20:29:14 +0800 From: Yuntao Wang <ytcoode@...il.com> To: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, Borislav Petkov <bp@...en8.de>, Dave Hansen <dave.hansen@...ux.intel.com>, x86@...nel.org Cc: "H . Peter Anvin" <hpa@...or.com>, linux-kernel@...r.kernel.org, Yuntao Wang <ytcoode@...il.com> Subject: [PATCH] x86/setup: Move duplicate variable definition out of the if/else block Both the if and else blocks define an exact same boot_cpu_data variable, move the duplicate variable definition out of the if/else block. In addition, this patch also does some other minor cleanups.
