Peter Anvin" <hpa@...or.com>, Igor Mammedov <imammedo@...hat.com> Subject: [PATCH] x86/smpboot: Remove unused phys_id variable The 'phys_id' local variable became unused after commit ce4b1b16502b ("x86/smpboot: Initialize secondary CPU only if master CPU will wait for it"). Remove it. Cc: Thomas Gleixner <tglx@...utronix.de> Cc: Ingo Molnar <mingo@...hat.com> Cc: Borislav Petkov <bp@...en8.de> Cc: "H.
