LLVM_IAS=1 controls enabling clang's integrated assembler via
-integrated-as. This was an explicit opt in until we could enable
assembler support in Clang for more architecures. Now we have support
and CI coverage of LLVM_IAS=1 for all architecures except a few more
bugs affecting s390 and powerpc.This commit flips the default from opt in via LLVM_IAS=1 to opt out via
LLVM_IAS=0. CI systems or developers that were previously doing builds
with CC=clang or LLVM=1 without explicitly setting LLVM_IAS must now
explicitly opt out via LLVM_IAS=0, otherwise they will be implicitly
opted-in.This finally shortens the command line invocation when cross compiling
with LLVM to simply:$ make ARCH=arm64 LLVM=1

"defconfig_list" is a weird option that defines a static symbol that
declares the list of base config files in case the .config does not
exist yet.This is quite different from other normal symbols; we just abused the
"string" type and the "default" properties to list out the input files.
They must be fixed values since these are searched for and loaded in
the parse stage.It is an ugly hack, and should not exist in the first place. Providing
this feature as an environment variable is a saner approach.Signed-off-by: Masahiro Yamada

The most common question around building the Linux kernel with clang is
"does it work?" and the answer has always been "it depends on your
architecture, configuration, and LLVM version" with no hard answers for
users wanting to experiment. LLVM support has significantly improved
over the past couple of years, resulting in more architectures and
configurations supported, and continuous integration has made it easier
to see what works and what does not.Add a section that goes over what architectures are supported in the
current kernel version, how they should be built (with just clang or the
LLVM utilities as well), and the level of support they receive. This
will make it easier for people to try out building their kernel with
LLVM and reporting issues that come about from it.Suggested-by: Miguel Ojeda

The difference between extra-y and always-y is obscure.
Basically, Kbuild builds targets listed in extra-y and always-y in
visited Makefiles without relying on any dependency.The difference is that extra-y is used to list the targets needed for
vmlinux whereas always-y is used to list the targets that must be always
built irrespective of final targets.Kbuild skips extra-y when it is building only modules (i.e.
'make modules'). This is the long-standing behavior since extra-y was
introduced in 2003, and it is explained in that commit log [1].For clarification, this is the extra-y vs always-y table:
extra-y always-y
'make' y y
'make vmlinux' y y
'make modules' n yKbuild skips extra-y also when building external modules since obviously
it never builds vmlinux.Unfortunately, extra-y is wrongly used in many places of upstream code,
and even in external modules.Using extra-y in external module Makefiles is wrong. What you should
use is probably always-y or 'targets'.The current documentation for extra-y is misleading. I rewrote it, and
moved it to the section 3.7.always-y is not documented anywhere. I added.

Precisely speaking, the arch directory is specified by $(SRCARCH),
not $(ARCH).In old days, $(ARCH) actually matched to the arch directory because
32-bit and 64-bit were supported as separate architectures.Most architectures (except arm/arm64) were unified like follows:
arch/i386, arch/x86_64 -> arch/x86
arch/sh, arch/sh64 -> arch/sh
arch/sparc, arch/sparc64 -> arch/sparcTo not break the user interface, commit 6752ed90da03 ("Kbuild: allow
arch/xxx to use a different source path") introduced SRCARCH to point
to the arch directory, still allowing to pass in the former ARCH=i386
or ARCH=x86_64.Update the documents for preciseness, and add the explanation of SRCARCH.

execute bit should not matter, and that build scripts cannot rely on that.
Kees could not point to any documentation, though.Masahiro Yamada explained the convention of setting execute bits to make
it easier for manual script invocation.Provide some basic documentation how the build shall invoke scripts, such
that the execute bits do not matter, and acknowledge that execute bits are
useful nonetheless.This serves as reference for further clean-up patches in the future.

Based on a vote at the LLVM BoF at Plumbers 2020, we decided to start
small, supporting just one formal upstream release of LLVM for now.We can probably widen the support window of supported versions over
time. Also, note that LLVM's release process is different than GCC's.
GCC tends to have 1 major release per year while releasing minor updates
to the past 3 major versions. LLVM tends to support one major release
and one minor release every six months.Signed-off-by: Nick Desaulniers

While reviewing a separate patch, I noticed that the formatting of the
commands, variables, and arguments was not in a monospaced font like the
rest of the Kbuild documentation (see kbuild/kconfig.rst for an
example). This is due to a lack of "::" before indented command blocks
and single backticks instead of double backticks for inline formatting.Add those so that the document looks nicer in an HTML format, while not
ruining the look in plain text.As a result of this, we can remove the escaped backslashes in the last
