From c92ff1bde06f69d59b40f3194016aee51cc5da55 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 16 Oct 2007 01:24:43 -0700 Subject: move mm_struct and vm_area_struct Move the definitions of struct mm_struct and struct vma_area_struct to include/mm_types.h. This allows to define more function in asm/pgtable.h and friends with inline assemblies instead of macros. Compile tested on i386, powerpc, powerpc64, s390-32, s390-64 and x86_64.
