This series of cleanups was prompted by Linus:
https://lkml.org/lkml/2020/3/12/726
First, this series drop always-on CONFIG_AS_* options.
Some of those options were introduced in old days.
For example, the check for CONFIG_AS_CFI dates back to 2006.
We raise the minimal tool versions from time to time.
Currently, we require binutils 2.21
(and we even plan to bump it to 2.23).
After cleaning away the old checks,
as-instr calls are moved to Kconfig from Makefiles,
then more Kconfig / Makefile code is cleaned up.
I folded all relevanet patches into this series,
as suggested by Jason A. Donenfeld.
The update for v2 is quite small.
I just swapped the patch order of patch 8 and 11
instead of moving comments around files,
which was addressed by Nick Desaulniers.

You can build a test program to test raid6 library code from user-space,
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'.
Fixes: 4f8c55c5ad49 ("lib/raid6: build proper files on corresponding arch")

This header file has the following check at the top:
#ifndef __ASSEMBLY__
#warning "asm/dwarf2.h should be only included in pure assembly files"
#endif
So, we expect defined(__ASSEMBLY__) is always true.

CONFIG_AS_CFI was introduced by commit e2414910f212 ("[PATCH] x86:
Detect CFI support in the assembler at runtime"), and extended by
commit f0f12d85af85 ("x86_64: Check for .cfi_rel_offset in CFI probe").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_CFI, which is always defined.

If this series is applied,
I can hard-code the assembler code, and delete CFI_* macros entirely.

Commit 131484c8da97 ("x86/debug: Remove perpetually broken,
unmaintainable dwarf annotations") removes all the users of
CFI_SIGNAL_FRAME.
Remove the CFI_SIGNAL_FRAME and CONFIG_AS_CFI_SIGNAL_FRAME.

CONFIG_AS_CFI_SECTIONS was introduced by commit 9e565292270a ("x86:
Use .cfi_sections for assembly code").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_CFI_SECTIONS, which is always defined.

CONFIG_AS_SSSE3 was introduced by commit 75aaf4c3e6a4 ("x86/raid6:
correctly check for assembler capabilities").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_SSSE3, which is always defined.
I added ifdef CONFIG_X86 to lib/raid6/algos.c to avoid link errors
on non-x86 architectures.
lib/raid6/algos.c is built not only for the kernel but also for
testing the library code from userspace. I added -DCONFIG_X86 to
lib/raid6/test/Makefile to cator to this usecase.

If the intention is to check i386/x86_64 excluding UML, testing
CONFIG_X86_{32,64} is simpler.
The reason for checking __i386__ / __x86_64__ was perhaps because
lib/raid6/algos.c is built not only for the kernel but also for
testing the library code from userspace.
However, lib/raid6/test/Makefile passes -DCONFIG_X86_{32,64} for
this case. So, I do not see a reason to not use CONFIG option here.

CONFIG_AS_MOVNTDQA was introduced by commit 0b1de5d58e19 ("drm/i915:
Use SSE4.1 movntdqa to accelerate reads from WC memory").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_MOVNTDQA, which is always defined.

CONFIG_AS_MOVNTDQA was introduced by commit 0b1de5d58e19 ("drm/i915:
Use SSE4.1 movntdqa to accelerate reads from WC memory").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_MOVNTDQA, which is always defined.

From: "Jason A. Donenfeld" <Jason@zx2c4.com>
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.

We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
We need to keep these as-instr checks because binutils 2.21 does not
support them.
I hope this will be a good hint which one can be dropped when we
bump the minimal binutils version next time.
As for the Clang/LLVM builds, we require very new LLVM version,
so the LLVM integrated assembler supports all of them.

Now that assembler capabilities are probed inside of Kconfig, we can set
up proper Kconfig-based dependencies. We also take this opportunity to
reorder the Makefile, so that items are grouped logically by primitive.

From: "Jason A. Donenfeld" <Jason@zx2c4.com>
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.

From: Borislav Petkov <bp@suse.de>
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.

* [PATCH v2 16/16] crypto: x86 - clean up poly1305-x86_64-cryptogams.S by 'make clean'

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 while cleaning
because scripts/Makefile.clean does not include include/config/auto.conf.
Removing the ifneq-conditional, so this file is correctly cleaned up.

Very little has changed from last time, and this whole series still
looks good to me. I think I already ack'd most packages, but in case
it helps:

Since this touches a lot of stuff, it might be best to get it in as
early as possible during the merge window, as I imagine new code being
added is going to want to be touching those makefiles too.

I'd argue the opposite: please merge this later in the merge window, to
not disrupt the vast body of other stuff that has already been lined up
and has been tested, and to give time for these new bits to get tested
some more.
Also, please get it into -next ASAP, today would be ideal for test
coverage ...
Thanks,
Ingo

Does KConfig generate -D<foo> flags for KBUILD_CFLAGS and KBUILD_AFLAGS?
Looks like lib/raid6/test/Makefile also generates some of these?

I see four checks for CONFIG_AS_AVX2 in:
net/netfilter/nft_set_pipapo.c
net/netfilter/nf_tables_api.c
net/netfilter/Makefile
net/netfilter/nft_set_pipapo_avx2.h
Can changes for those be added to this?

I see four checks for CONFIG_AS_AVX2 in:
net/netfilter/nft_set_pipapo.c
net/netfilter/nf_tables_api.c
net/netfilter/Makefile
net/netfilter/nft_set_pipapo_avx2.h
Can changes for those be added to this?

kconfig sticks everything it's got into include/generated/autoconf.h.
That's how you're able to use all those #ifdef CONFIG_* macros
already. This change moves things from a command line -D to the
autoconf.h file.

raid6 has its own crazy thing going on. The test directory compiles
that code for use in userspace. You might argue that its whole
situation is non-standard and weird and should be reworked
differently, but that seems like fodder for a different patchset on
the linux-raid list.

I think rebasing on -next is the way to go. I usually generate my
patches off of that, though some trees that don't feed into -next are
technically further ahead.

Cool, I wondered how that was wired up. Though seeing the word
"autoconf" brings on PTSD for me.
Patch LGTM.

Now that the kernel specifies binutils 2.23 as the minimum version, we
can remove ifdefs for AVX2 and ADX throughout.

Masahiro - here's an updated patch based on -next, as Nick requested.
Whether or not you'd prefer this one to the other one based on Linus'
tree is up to you, but here it is in case it's helpful.

Thanks.
When the netfilter PR is pulled,
I will rebase on top of Linus' tree.

This hunk should go to:
[v2,10/16] x86: probe assembler capabilities via kconfig instead of makefile
I will try my best to remember this.

Sorry, this patch broke UML builds.
https://lkml.org/lkml/2020/3/27/618
I will drop this patch for tomorrow's linux-next.
CONFIG_X86 is not defined for ARCH=um.
So, I still think it is OK to replace one complicated line
in lib/raid6/x86.h
#if (defined(__i386__) || defined(__x86_64__)) && !defined(__arch_um__)
with:
#ifdef CONFIG_X86
Also, I slightly prefer
#if defined(CONFIG_X86_32) && !defined(CONFIG_UML)
to
#if defined(__i386__) && !defined(__arch_um__)
But, we do not need to rush this now.
This patch does not affect the rest of this series.
Thanks.

I would much prefer that too.
At some point it'd be nice to see this whole mess cleaned up with UML.
I've seen this a few places -- UML thinks its x86, except where it's
not, and then there are problems. For example, a lot of SIMD related
code has this.
