scripts/mkcompile_h uses $(CC) only for getting the version string. I suspected there was a specific reason why the additional flags were needed, and dug the commit history. This code dates back to at least 2002 [1], but I could not get any more clue. Just get rid of it.

When doing Clang builds of the kernel, it is possible to link with either ld.bfd (binutils) or ld.lld (LLVM), but it is not possible to discover this from a running kernel. Add the "$LD -v" output to /proc/version. Signed-off-by:

At least on my tests (building against Qt5.13), it seems to me that, since Kernel 3.14, the split view mode is broken. Maybe it was not a top priority during the conversion time. Anyway, this patch changes the logic in order to properly support the split view mode and the single view mode. Signed-off-by:

The port to Qt5 tried to preserve the same way as it used to work with Qt3 and Qt4. However, at least with newer versions of Qt5 (5.13), this doesn't work properly. Change the schema by adding a vertical layout, in order for it to start working properly again. Signed-off-by:

Nobody was opposed to raising minimum GCC version to 4.8 [1] So, we will drop GCC <= 4.7 support sooner or later. We always use C++ compiler for building plugins for GCC >= 4.8. This commit drops the plugin support for GCC <= 4.7 a bit earlier, which allows us to dump lots of code. [1] https://lkml.org/lkml/2020/1/23/545Signed-off-by:

Currently, we disable -Wtautological-compare, which in turn disables a bunch of more specific tautological comparison warnings that are useful for the kernel such as -Wtautological-bitwise-compare. See clang's documentation below for the other warnings that are suppressed by -Wtautological-compare. Now that all of the major/noisy warnings have been fixed, enable -Wtautological-compare so that more issues can be caught at build time by various continuous integration setups. -Wtautological-constant-out-of-range-compare is kept disabled under a normal build but visible at W=1 because there are places in the kernel where a constant or variable size can change based on the kernel configuration. These are not fixed in a clean/concise way and the ones I have audited so far appear to be harmless. It is not a subgroup but rather just one warning so we do not lose out on much coverage by default.

poly1305-x86_64-cryptogams.S is a generated file, so it should be cleaned up by 'make clean'. Assigning it to the variable 'targets' teaches Kbuild that it is a generated file. However, this line is not evaluated when cleaning because scripts/Makefile.clean does not include include/config/auto.conf. Remove the ifneq-conditional, so this file is correctly cleaned up.

The currently minimum-supported binutils version 2.21 has the problem of promoting symbols which are defined outside of a section into absolute. According to Arvind: binutils-2.21 and -2.22. An x86-64 defconfig will fail with Invalid absolute R_X86_64_32S relocation: _etext and after fixing that one, with Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve Those two versions of binutils have a bug when it comes to handling symbols defined outside of a section and binutils 2.23 has the proper fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html Therefore, up to the fixed version directly, skipping the broken ones. Currently shipping distros already have the fixed binutils version so there should be no breakage resulting from this. For more details about the whole thing, see the thread in Link. Signed-off-by:

Since we're doing a static inline dispatch here, we normally branch based on whether or not there's an arch implementation. That would have been fine in general, except the crypto Makefile prior used to turn things off -- despite the Kconfig -- resulting in us needing to also hard code various assembler things into the dispatcher too. The horror! Now that the assembler config options are done by Kconfig, we can get rid of the inconsistency. Signed-off-by:

We raise the minimal supported binutils version from time to time. The last bump was commit 1fb12b35 ("kbuild: Raise the minimum required binutils version to 2.21"). We have these as-instr tests because binutils 2.21 does not support them. When we bump the binutils version next time, this will be a good hint to find out which one can be dropped. As for the Clang/LLVM builds, we require very new LLVM version, so the LLVM integrated assembler supports all of them. Signed-off-by:

Doing this probing inside of the Makefiles means we have a maze of ifdefs inside the source code and child Makefiles that need to make proper decisions on this too. Instead, we do it at Kconfig time, like many other compiler and assembler options, which allows us to set up the dependencies normally for full compilation units. In the process, the ADX test changes to use %eax instead of %r10 so that it's valid in both 32-bit and 64-bit mode. Signed-off-by:

You can build a user-space test program for the raid6 library code, like this: $ cd lib/raid6/test $ make The command in $(shell ...) function is evaluated by /bin/sh by default. (or, you can specify the shell by passing SHELL=<shell> from command line) Currently '>&/dev/null' is used to sink both stdout and stderr. Because this code is bash-ism, it only works when /bin/sh is a symbolic link to bash (this is the case on RHEL etc.) This does not work on Ubuntu where /bin/sh is a symbolic link to dash. I see lots of /bin/sh: 1: Syntax error: Bad fd number and warning "your version of binutils lacks ... support" Replace it with portable '>/dev/null 2>&1'.

It's definitely incorrect to mark the lock as taken even if down_read_killable() failed. This wass overlooked when we switched from down_read() to down_read_killable() because down_read() won't fail while down_read_killable() could.

lookup_node() uses gup to pin the page and get node information. It checks against ret>=0 assuming the page will be filled in. However it's also possible that gup will return zero, for example, when the thread is quickly killed with a fatal signal. Teach lookup_node() to gracefully return an error -EFAULT if it happens. Meanwhile, initialize "page" to NULL to avoid potential risk of exploiting the pointer.

A couple of misc fixes/workarounds for some issues that are causing a lot of pain for people. Of most interest are the PCI power management and GR init WARs, which effect a rather significant number of laptop systems that are in use today. Signed-off-by:
