From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- .../arch/microblaze/include/asm/highmem.h | 96 ---------------------- 1 file changed, 96 deletions(-) delete mode 100644 ANDROID_3.4.5/arch/microblaze/include/asm/highmem.h (limited to 'ANDROID_3.4.5/arch/microblaze/include/asm/highmem.h') diff --git a/ANDROID_3.4.5/arch/microblaze/include/asm/highmem.h b/ANDROID_3.4.5/arch/microblaze/include/asm/highmem.h deleted file mode 100644 index 2446a731..00000000 --- a/ANDROID_3.4.5/arch/microblaze/include/asm/highmem.h +++ /dev/null @@ -1,96 +0,0 @@ -/* - * highmem.h: virtual kernel memory mappings for high memory - * - * Used in CONFIG_HIGHMEM systems for memory pages which - * are not addressable by direct kernel virtual addresses. - * - * Copyright (C) 1999 Gerhard Wichert, Siemens AG - * Gerhard.Wichert@pdb.siemens.de - * - * - * Redesigned the x86 32-bit VM architecture to deal with - * up to 16 Terabyte physical memory.
