From 4fbb5968810b237e81977f131986b9efd5245368 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 2 May 2007 19:27:11 +0200 Subject: [PATCH] i386: cleanup GDT Access Now we have an explicit per-cpu GDT variable, we don't need to keep the descriptors around to use them to find the GDT: expose cpu_gdt directly. We could go further and make load_gdt() pack the descriptor for us, or even assume it means "load the current cpu's GDT" which is what it always does.
