From 934d15854d04e8ca2495d8f5698164df990d5d66 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 30 Jan 2008 13:33:53 +0100 Subject: x86: remove set_kernel_exec() The SMP trampoline always runs in real mode, so making it executable in the page tables doesn't make much sense because it executes before page tables are set up. That was the only user of set_kernel_exec(). Remove set_kernel_exec().
