From b3ee571e58120de30c3d15657022bf2c72477e02 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 18 Aug 2011 20:10:49 +0100 Subject: um: take ldt.h to arch/x86/um/asm/mm_context.h it's x86-only and we have no business playing with it in asm/mmu.h; make the latter have struct uml_arch_mm_context arch; instead of struct uml_ldt ldt; and let arch//um/asm/mm_context.h decide what'll be in there. While we are at it, kill host_ldt.h - it's not needed in part of places that include it (we want asm/ldt.h in those) and it can be trivially expanded into the single remaining one.
