From 1f8d419e291f7f7f7f3ffd4f0ba00834621690c8 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 5 May 2005 16:15:13 -0700 Subject: [PATCH] ppc64: pgtable.h and other header cleanups This patch started as simply removing a few never-used macros from asm-ppc64/pgtable.h, then kind of grew. It now makes a bunch of cleanups to the ppc64 low-level header files (with corresponding changes to .c files where necessary) such as: - Abolishing never-used macros - Eliminating multiple #defines with the same purpose - Removing pointless macros (cases where just expanding the macro everywhere turns out clearer and more sensible) - Removing some cases where macros which could be defined in terms of each other weren't - Moving imalloc() related definitions from pgtable.h to their own header file (imalloc.h) - Re-arranging headers to group things more logically - Moving all VSID allocation related things to mmu.h, instead of being split between mmu.h and mmu_context.h - Removing some reserved space for flags from the PMD - we're not using it. - Fix some bugs which broke compile with STRICT_MM_TYPECHECKS.
