| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update dtx_diff include paths in the same manner as: commit b12869a8d519 ("of: remove drivers/of/testcase-data from include search path for CPP"), commit 5ffa2aed389c ("of: remove arch/$(SRCARCH)/boot/dts from include search path for CPP"), and commit 50f9ddaf64e1 ("of: search scripts/dtc/include-prefixes path for both CPP and DTC"). Remove proposed include path kernel/dts/, which was never implemented for the dtb build. For the diff case, each source file is compiled separately. For each of those compiles, provide the location of the source file as an include path, not the location of both source files.

* | kbuild: rpm-pkg: fix version number handlingMasahiro Yamada2017-09-213-15/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "Release:" field of the spec file is determined based on the .version file. However, the .version file is not copied to the source tar file. So, when we build the kernel from the source package, the UTS_VERSION always indicates #1. This does not match with "rpm -q". The kernel UTS_VERSION and "rpm -q" do not agree for binrpm-pkg, either. Please note the kernel has already been built before the spec file is created. Currently, mkspec invokes mkversion. This script returns an incremented version. So, the "Release:" field of the spec file is greater than the version in the kernel by one. For the source package build (where .version file is missing), we can give KBUILD_BUILD_VERSION=%{release} to the build command. For the binary package build, we can simply read out the .version file because it contains the version number that was used for building the kernel image. We can remove scripts/mkversion because scripts/package/Makefile need not touch the .version file. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Commit df85b2d767aa ("firmware: Restore support for built-in firmware") restored the build infrastructure for CONFIG_EXTRA_FIRMWARE, but this is out of the scope of "make firmware_install".

For some minor reason, David Woodhouse didn't send the pull request at that point in time, and everyone forgot about this. The topic came up in the hallway track at the Plumbers conference this week, so here's a single patch that drops the whole firmware tree. The last firmware update was back in 2013, and all distros have been using linux-firmware instead since at least that year, if not before. The only commits to that directory since 2013 was some kbuild fixups for various build tool issues. So lets finally drop this, we don't need to lug them around in the kernel source tree anymore, especially as no one wants or uses them. This has passed build testing with 0-day, I don't think it made it into linux-next this week, but I figured it was good to get in before 4.14-rc1 was out" * tag 'firmware_removal-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: firmware: delete in-kernel firmware

Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81") dropped the GNU Make 3.80 support, so we are now allowed to use those make-builtin helpers. This conversion will provide better portability without relying on the pwd command or its location /bin/pwd. I am intentionally using $(realpath ...) instead $(abspath ...) in some places. The difference between the two is $(realpath ...) returns an empty string if the given path does not exist. It is convenient in places where we need to error-out if the makefile fails to create an output directory.

That worked pretty good with Sphinx versions 1.4 and 1.5, but Spinx 1.6 changed the way tables are produced, by introducing some weird macros before tabulary. That causes adjustbox to fail.

I had changed that function to return the token ID directly rather than a pointer to the token descriptor structure, but that meant that the test for "is this a reserved word" changed from checking the return value against NULL, to checking that it wasn't negative. And while I had converted the main token parser over, I missed the special case of the typeof phrase handling. And since our dependency chain for genksyms does not include the genksyms program itself changing, my kernel rebuild didn't show the problem.

This removal was prompted by Masahiro Yamada sending out a patch that removes all our pre-generated files, and when I tested it, I noticed that the gperf version I have (3.1) apparently generates code that no longer works with out code-base because the function interfaces generated by gperf have changed. We really don't care that much, and the gperf people changed their interfaces in ways that makes it annoying to work with them. Tools that make it hard to use them should not be used, and the kernel is not at all interested in some autoconf mess. So remove the gperf dependency entirely. It turns out that if you ignore the pre-generated files, the use of gperf apparently saved us a whopping fifteen lines of code. It obviously wasn't worth it, considering that the pre-generated files are about 500 lines. I sent this out as a patch about three weeks ago, and got absolutely zero responses. So let's see if anybody notices now that I merge it. Because there might be serious bugs here, but it WorksForMe(tm). * gperf-removal: Remove gperf usage from toolchain

If the initalization function is not part of the same compilation unit, the lack of an assignment operation defeats any analysis the compiler can perform as to whether the variable may be used before having been initialized. This means we may end up passing on such variables uninitialized, resulting in potential information leaks. So extend the existing structleak GCC plugin so it will [optionally] apply to all struct type variables that have their address taken at any point, rather than only to variables of struct types that have a __user annotation.

The ORC unwinder is a lightweight, Linux kernel specific debuginfo implementation, which aims to be DWARF done right for unwinding. Objtool is used to generate the ORC unwinder tables during build, so the data format is flexible and kernel internal: there's no dependency on debuginfo created by an external toolchain. The ORC unwinder is almost two orders of magnitude faster than the (out of tree) DWARF unwinder - which is important for perf call graph profiling. It is also significantly simpler and is coded defensively: there has not been a single ORC related kernel crash so far, even with early versions. (knock on wood!) But the main advantage is that enabling the ORC unwinder allows CONFIG_FRAME_POINTERS to be turned off - which speeds up the kernel measurably: With frame pointers disabled, GCC does not have to add frame pointer instrumentation code to every function in the kernel. The kernel's .text size decreases by about 3.2%, resulting in better cache utilization and fewer instructions executed, resulting in a broad kernel-wide speedup. Average speedup of system calls should be roughly in the 1-3% range - measurements by Mel Gorman [1] have shown a speedup of 5-10% for some function execution intense workloads. The main cost of the unwinder is that the unwinder data has to be stored in RAM: the memory cost is 2-4MB of RAM, depending on kernel config - which is a modest cost on modern x86 systems. Given how young the ORC unwinder code is it's not enabled by default - but given the performance advantages the plan is to eventually make it the default unwinder on x86. See Documentation/x86/orc-unwinder.txt for more details. - Remove lguest support: its intended role was that of a temporary proof of concept for virtualization, plus its removal will enable the reduction (removal) of the paravirt API as well, so Rusty agreed to its removal.

It plugs into the existing x86 unwinder framework. It relies on objtool to generate the needed .orc_unwind and .orc_unwind_ip sections. For more details on why ORC is used instead of DWARF, see Documentation/x86/orc-unwinder.txt - but the short version is that it's a simplified, fundamentally more robust debugninfo data structure, which also allows up to two orders of magnitude faster lookups than the DWARF unwinder - which matters to profiling workloads like perf.

However, the 0-day bot is still reporting some unreachable instruction warnings with CONFIG_GCOV_KERNEL=y on GCC 4.6.4. As it turns out, objtool's gcov detection doesn't work with older versions of GCC because they don't create a bunch of symbols with the 'gcov.' prefix like newer versions of GCC do. Move the gcov check out of objtool and instead just create a new '--no-unreachable' flag which can be passed in by the kernel Makefile when CONFIG_GCOV_KERNEL is defined. Also rename the 'nofp' variable to 'no_fp' for consistency with the new 'no_unreachable' variable.

So, remove this from the list of requirements for all distributions. With regards to PDF, we need at least texlive-tabulary extension, but that is not shipped there (at least on CentOS). So, disable PDF packages as a whole. Please notice, however, that texlive + amsmath is needed for ReST to properly handle ReST ".. math::" tags.
