From 4fe2d8b11a370af286287a2661de9d4e6c9a145a Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Mon, 4 Dec 2017 17:25:07 -0800 Subject: x86/entry: Rename SYSENTER_stack to CPU_ENTRY_AREA_entry_stack If the kernel oopses while on the trampoline stack, it will print "" even if SYSENTER is not involved. That is rather confusing. The "SYSENTER" stack is used for a lot more than SYSENTER now. Give it a better string to display in stack dumps, and rename the kernel code to match. Also move the 32-bit code over to the new naming even though it still uses the entry stack only for SYSENTER.
