m68k: merge mmu and non-mmu arch Makefiles Most of the build logic is the same for the mmu and non-mmu m68k targets. Merge the top level architecture Makefiles back into a single Makefile. For the most part this is just adding the non-mmu processor types and their specific cflags and other options into the mmu Makefile. Note that all the BOARD setting logic that was in the non-mmu Makefile is completely removed. It was no longer being used at all. This has been build and run tested on ColdFire targets and ARAnyM. It has been build tested on all the m68k defconfig targets using a gcc-4.5.1 based toolchain. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Sam Ravnborg <sam@ravnborg.org>

kbuild: use more subdir- for visiting subdirectories while cleaning Documentation/kbuild/makefiles.rst suggests to use "archclean" for cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement. Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures. This can take advantage of the parallel option (-j) for "make clean". I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep" target no longer exists.

arch: use cross_compiling to check whether it is a cross build or not 'cross_compiling' is defined by the top Makefile and available for arch Makefiles to check whether it is a cross build or not. A good thing is the variable name 'cross_compiling' is self-documenting. This is a simple replacement for m68k, mips, sh, for which $(ARCH) and $(SRCARCH) always match. No functional change is intended for xtensa, either. This is rather a fix for parisc because arch/parisc/Makefile defines UTS_MATCHINE depending on CONFIG_64BIT, therefore cc-cross-prefix is not working in Kconfig time.

m68k: Optimize cc-option calls for cpuflags-y arch/m68k/Makefile computes lots of unneeded cc-option calls. For example, if CONFIG_M5441x is not defined, there is not point in evaluating the following compiler flag. cpuflags-$(CONFIG_M5441x) := $(call cc-option,-mcpu=54455,-mcfv4e) The result is set to cpuflags-, then thrown away. The right hand side of ':=' is immediately expanded. Hence, all of the 16 calls for cc-option are evaluated. This is expensive since cc-option invokes the compiler. This occurs even if you are not attempting to build anything, like 'make ARCH=m68k help'. Use '=' to expand the value _lazily_. The evaluation for cc-option is delayed until $(cpuflags-y) is expanded. So, the cc-option test happens just once at most. This commit mimics tune-y of arch/arm/Makefile.

m68k: Add -ffreestanding to CFLAGS This patch fixes a build failure when using GCC 8.1: /usr/bin/ld: block/partitions/ldm.o: in function `ldm_parse_tocblock': block/partitions/ldm.c:153: undefined reference to `strcmp' This is caused by a new optimization which effectively replaces a strncmp() call with a strcmp() call. This affects a number of strncmp() call sites in the kernel. The entire class of optimizations is avoided with -fno-builtin, which gets enabled by -ffreestanding. This may avoid possible future build failures in case new optimizations appear in future compilers. I haven't done any performance measurements with this patch but I did count the function calls in a defconfig build. For example, there are now 23 more sprintf() calls and 39 fewer strcpy() calls. The effect on the other libc functions is smaller. If this harms performance we can tackle that regression by optimizing the call sites, ideally using semantic patches. That way, clang and ICC builds might benfit too.

m68k: merge m68k and m68knommu arch directories There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King <sfking@fdwdc.com>, which was originally written by Arnd Bergmann <arnd@arndb.de>. > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include <file>_mm.<ext> > #else > #include <file>_no.<ext> > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

m68k: merge mmu and non-mmu arch Makefiles Most of the build logic is the same for the mmu and non-mmu m68k targets. Merge the top level architecture Makefiles back into a single Makefile. For the most part this is just adding the non-mmu processor types and their specific cflags and other options into the mmu Makefile. Note that all the BOARD setting logic that was in the non-mmu Makefile is completely removed. It was no longer being used at all. This has been build and run tested on ColdFire targets and ARAnyM. It has been build tested on all the m68k defconfig targets using a gcc-4.5.1 based toolchain. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Sam Ravnborg <sam@ravnborg.org>

m68k: Generate uapi header and syscall table header files System call table generation script must be run to gener- ate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by m68k/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/syscalltable.S file.

kbuild: factor out the common installation code into scripts/install.sh Many architectures have similar install.sh scripts. The first half is really generic; it verifies that the kernel image and System.map exist, then executes ~/bin/${INSTALLKERNEL} or /sbin/${INSTALLKERNEL} if available. The second half is kind of arch-specific; it copies the kernel image and System.map to the destination, but the code is slightly different. Factor out the generic part into scripts/install.sh.
