From b32f96c75d0dcbb9bf9cc7994e8022c8ce20a668 Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Thu, 18 Aug 2016 10:59:03 -0500 Subject: x86/asm/head: Rename 'stack_start' -> 'initial_stack' The 'stack_start' variable is similar in usage to 'initial_code' and 'initial_gs': they're all stored in head_64.S and they're all updated by SMP and ACPI suspend before starting a CPU. Rename it to 'initial_stack' to be consistent with the others.
