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!

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

ARM: 9038/1: Link with '-z norelro' When linking a multi_v7_defconfig + CONFIG_KASAN=y kernel with LD=ld.lld, the following error occurs: $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- LLVM=1 zImage ld.lld: error: section: .exit.data is not contiguous with other relro sections LLD defaults to '-z relro', which is unneeded for the kernel because program headers are not used nor is there any position independent code generation or linking for ARM. Add '-z norelro' to LDFLAGS_vmlinux to avoid this error.

arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0 Albin Tonnerre <albin.tonnerre@free-electrons.com> reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

kbuild: enable 'make CFLAGS=...' to add additional options to CC The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

ARM: 8429/1: disable GCC SRA optimization While working on the 32-bit ARM port of UEFI, I noticed a strange corruption in the kernel log.

The following code if (!(spec.flags & LEFT)) { while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } } for (i = 0; i < len; ++i) { if (buf < end) *buf = *s; ++buf; ++s; } while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } when called with len == 0, triggers an issue in the GCC SRA optimization pass (Scalar Replacement of Aggregates), which handles promotion of signed struct members incorrectly. This is a known but as yet unresolved issue. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular case, it is causing the second while loop to be executed erroneously a single time, causing the additional space characters to be printed. So disable the optimization by passing -fno-ipa-sra.

ARM: 8801/1: makefile: use ARMv3M mode for RiscPC The purpose of CONFIG_CPU_32v3 is to avoid ldrh/strh on the RiscPC, which is pretty much an ARMv4 device, except its bus will choke on the half-words. The way to make the C compiler not output ldrh/strh is with -march=armv3, which doesn't support them in the ISA. However, this prevents certain cryptography code from working that uses instructions like umull. Fortunately there's also -march=armv3m that does support those, making it possible to continue assembling optimized cryptography routines for our beloved RiscPC. Signed-off-by: Jason A.

Always build with '-meabi gnu' when using clang but ensure that '-pg' (which is added with CONFIG_FUNCTION_TRACER and its prereq CONFIG_HAVE_FUNCTION_TRACER) cannot be added with it unless this is fixed (which means using clang 10.0.0 and newer).

ARM: 8723/2: always assume the "unified" syntax for assembly code The GNU assembler has implemented the "unified syntax" parsing since 2005. This "unified" syntax is required when the kernel is built in Thumb2 mode. However the "unified" syntax is a mixed bag of features, including not requiring a `#' prefix with immediate operands. This leads to situations where some code builds just fine in Thumb2 mode and fails to build in ARM mode if that prefix is missing. This behavior discrepancy makes build tests less valuable, forcing both ARM and Thumb2 builds for proper coverage. Let's "fix" this issue by always using the "unified" syntax for both ARM and Thumb2 mode. Given that the documented minimum binutils version that properly builds the kernel is version 2.20 released in 2010, we can assume that any toolchain capable of building the latest kernel is also "unified syntax" capable. Whith this, a bunch of macros used to mask some differences between both syntaxes can be removed, with the side effect of making LTO easier.

When building a kernel for a CPU that does not support THUMB2, the compiler complains about incorrect flags. We can work around this by setting -marm for all non-T2 builds. -marm was passed unconditionally for C files previously, but nothing was passed to the gcc frontend when processing .S files, resulting in a warning.

kbuild: add machine size to CHECKFLAGS By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else. This can of course create all sort of problems for the other archs, like issuing false warnings ('shift too big (32) for type unsigned long'), or worse, failing to emit legitimate warnings. Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT, to CHECKFLAGS in the main Makefile (and so for all archs). Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.

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!

ARM: 7012/1: Set proper TEXT_OFFSET for newer MSMs MSMs post 8x50 have 2Mb at the beginning of RAM reserved for shared memory. Since the kernel hasn't typically been told this RAM exists, PHYS_OFFSET has been set to 0xN0200000 and the memory atags passed to the kernel have matched. This doesn't play nicely with things such as AUTO_ZRELADDR, which doesn't work at all, and dynamic phys to virt, which requires an MSM specific workaround. Work around these issues by telling the kernel RAM starts at 0xN0000000 (it actually does) and fixup the atags from the bootloader (if necessary) to say the same. In addition, make sure to set TEXT_OFFSET at least 2Mb beyond the start of RAM so that the kernel doesn't end up being decompressed into shared memory. After doing this, AUTO_ZRELADDR should work on MSM with no problems and ARM_PATCH_PHYS_VIRT_16BIT should no longer be necessary.

However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols.

ARM: initial multiplatform support This lets us build a multiplatform kernel for experimental purposes. However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename. As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank, picoxcell, mvebu, and socfpga are converted.

[ARM] 3097/1: change library link ordering Patch from Nicolas Pitre We have an optimized sha1 routine (arch/arm/lib/sha1.S) meant to override the generic one in lib/sha1.c. Unfortunately lib/lib.a is listed _before_ arch/arm/lib/lib.a in the link argument list and therefore the architecture specific lib functions are not picked up before the generic versions. This patch is a quick fix to change that ordering for ARM. Here's what the kbuild maintainer had to say about it (was also CC'd on lkml): On Wed, 2 Nov 2005, Sam Ravnborg wrote: > This looks like an obvious way to achive correct ordering. > We could change it so arch defines always took precedence but > the above is so simple that it is not worth the effort.

ARM: smp: add support for per-task stack canaries On ARM, we currently only change the value of the stack canary when switching tasks if the kernel was built for UP. On SMP kernels, this is impossible since the stack canary value is obtained via a global symbol reference, which means a) all running tasks on all CPUs must use the same value b) we can only modify the value when no kernel stack frames are live on any CPU, which is effectively never. So instead, use a GCC plugin to add a RTL pass that replaces each reference to the address of the __stack_chk_guard symbol with an expression that produces the address of the 'stack_canary' field that is added to struct thread_info. This way, each task will use its own randomized value.

ARM: 8961/2: Fix Kbuild issue caused by per-task stack protector GCC plugin When using plugins, GCC requires that the -fplugin= options precedes any of its plugin arguments appearing on the command line as well. This is usually not a concern, but as it turns out, this requirement is causing some issues with ARM's per-task stack protector plugin and Kbuild's implementation of $(cc-option). When the per-task stack protector plugin is enabled, and we tweak the implementation of cc-option not to pipe the stderr output of GCC to /dev/null, the following output is generated when GCC is executed in the context of cc-option: cc1: error: plugin arm_ssp_per_task_plugin should be specified before \ -fplugin-arg-arm_ssp_per_task_plugin-tso=1 in the command line cc1: error: plugin arm_ssp_per_task_plugin should be specified before \ -fplugin-arg-arm_ssp_per_task_plugin-offset=24 in the command line These errors will cause any option passed to cc-option to be treated as unsupported, which is obviously incorrect. The cause of this issue is the fact that the -fplugin= argument is added to GCC_PLUGINS_CFLAGS, whereas the arguments above are added to KBUILD_CFLAGS, and the contents of the former get filtered out of the latter before being passed to the GCC running the cc-option test, and so the -fplugin= option does not appear at all on the GCC command line. Adding the arguments to GCC_PLUGINS_CFLAGS instead of KBUILD_CFLAGS would be the correct approach here, if it weren't for the fact that we are using $(eval) to defer the moment that they are added until after asm-offsets.h is generated, which is after the point where the contents of GCC_PLUGINS_CFLAGS are added to KBUILD_CFLAGS. So instead, we have to add our plugin arguments to both. For similar reasons, we cannot append DISABLE_ARM_SSP_PER_TASK_PLUGIN to KBUILD_CFLAGS, as it will be passed to GCC when executing in the context of cc-option, whereas the other plugin arguments will have been filtered out, resulting in a similar error and false negative result as above.

kbuild: consolidate Devicetree dtb build rules There is nothing arch specific about building dtb files other than their location under /arch/*/boot/dts/. Keeping each arch aligned is a pain. The dependencies and supported targets are all slightly different. Also, a cross-compiler for each arch is needed, but really the host compiler preprocessor is perfectly fine for building dtbs. Move the build rules to a common location and remove the arch specific ones. This is done in a single step to avoid warnings about overriding rules. The build dependencies had been a mixture of 'scripts' and/or 'prepare'. These pull in several dependencies some of which need a target compiler (specifically devicetable-offsets.h) and aren't needed to build dtbs. All that is really needed is dtc, so adjust the dependencies to only be dtc. This change enables support 'dtbs_install' on some arches which were missing the target.

# Convert bzImage to zImage
bzImage: zImage
arm, kbuild: make "make install" not depend on vmlinux Install targets (install, zinstall, uinstall) on arm have a dependency to vmlinux. This may cause parts of the kernel to be rebuilt during installation. We must avoid this since this may run as root. Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus emphasized this in: http://lkml.org/lkml/2013/7/10/600 So on arm and maybe other archs we need the same as for x86: 1648e4f8 x86, kbuild: make "make install" not depend on vmlinux This patch fixes this for arm. Dependencies are removed and instead a check to install.sh is added for the files that are needed. This issue was uncovered by this build error where the -j option is used in conjunction with install targets: $ make <makeflags> $ make <makeflags> zinstall ... DEPMOD Usage: .../scripts/depmod.sh /sbin/depmod <kernelrelease> (INSTALL_MOD_PATH and INSTALL_PATH variables set, so no root perms required in this case.) The problem is that zinstall on arm due to its dependency to vmlinux does a prepare/prepare3 and finally does a forced rewrite of kernel.release even if it exists already. Rebuilding kernel.release removes it first and then recreates it. This might race with another parallel make job running depmod. So this patch should fix this one too. Also quoting $(KERNELRELEASE) arg for install.sh as this messes argument order in case it is empty (which is the case if the kernel was not built yet).

ARM: 8418/1: add boot image dependencies to not generate invalid images U-Boot is often used to boot the kernel on ARM boards, but uImage is not built by "make all", so we are often inclined to do "make all uImage" to generate DTBs, modules and uImage in a single command, but we should notice a pitfall behind it. In fact, "make all uImage" could generate an invalid uImage if it is run with the parallel option (-j). You can reproduce this problem with the following procedure: [1] First, build "all" and "uImage" separately.

Besides, "Kernel: arch/arm/boot/zImage is ready" is displayed twice, before and after the uImage log. The root cause of this is the race condition between zImage and uImage. Actually, uImage depends on zImage, but the dependency between the two is only described in arch/arm/boot/Makefile. Because arch/arm/boot/Makefile is not included from the top-level Makefile, it cannot know the dependency between zImage and uImage. Consequently, when we run make with the parallel option, Kbuild updates vmlinux first, and then two different threads descends into the arch/arm/boot/Makefile almost at the same time, one for updating zImage and the other for uImage. While one thread is re-generating zImage, the other also tries to update zImage before creating uImage on top of that. zImage is overwritten by the slower thread and then uImage is created based on the half-written zImage. This is the reason why "Kernel: arch/arm/boot/zImage is ready" is displayed twice, and a broken uImage is created. The same problem could happen on bootpImage. This commit adds dependencies among Image, zImage, uImage, and bootpImage to arch/arm/Makefile, which is included from the top-level Makefile.

arm, kbuild: make "make install" not depend on vmlinux Install targets (install, zinstall, uinstall) on arm have a dependency to vmlinux. This may cause parts of the kernel to be rebuilt during installation. We must avoid this since this may run as root. Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus emphasized this in: http://lkml.org/lkml/2013/7/10/600 So on arm and maybe other archs we need the same as for x86: 1648e4f8 x86, kbuild: make "make install" not depend on vmlinux This patch fixes this for arm. Dependencies are removed and instead a check to install.sh is added for the files that are needed. This issue was uncovered by this build error where the -j option is used in conjunction with install targets: $ make <makeflags> $ make <makeflags> zinstall ... DEPMOD Usage: .../scripts/depmod.sh /sbin/depmod <kernelrelease> (INSTALL_MOD_PATH and INSTALL_PATH variables set, so no root perms required in this case.) The problem is that zinstall on arm due to its dependency to vmlinux does a prepare/prepare3 and finally does a forced rewrite of kernel.release even if it exists already. Rebuilding kernel.release removes it first and then recreates it. This might race with another parallel make job running depmod. So this patch should fix this one too. Also quoting $(KERNELRELEASE) arg for install.sh as this messes argument order in case it is empty (which is the case if the kernel was not built yet).

ARM: 8576/1: avoid duplicating "Kernel: arch/arm/boot/*Image is ready" Commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not generate invalid images") fixed bad image generation for the parallel building, but as its side effect, Kbuild now descends into arch/arm/boot/ again and again, duplicating the log messages. It looks clumsy, so let's display the same message only once. This commit moves the log rules from arch/arm/boot/Makefile to arch/arm/Makefile. I did not delete them completely because *Image are the final targets that users are interested in.

kbuild: use INSTALLKERNEL to select customized installkernel script Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.
