From 0a41e2501160587eb8f66cef3bdf1c6f2cb86997 Mon Sep 17 00:00:00 2001 From: Peter Chubb Date: Tue, 16 Aug 2005 19:54:00 -0700 Subject: [IA64] Rationalise Region Definitions Currently, region numbers are defined in several files, with several names. For example, we have REGION_KERNEL in asm/page.h and RGN_KERNEL in pgtable.h We also have address definitions that should depend on the RGN_XXX macros, but are currently just long constants. The following patch reorganises all the definitions so that they have the same form (RGN_XXX), are in one place, and that addresses that depend on RGN_XXX are derived from them. (This is a necessary but not sufficient patch to allow UML-like operation on IA64). Thanks to David Mosberger for catching the change I missed in mmu_context.h.
