We need to add "clean-files" in Makfiles to clean up DT blobs, but we
often miss to do so.Since there are no source files that end with .dtb or .dtb.S, so we
can clean-up those files from the top-level Makefile.Signed-off-by: Masahiro Yamada

"Thin archives migration by Nicholas Piggin.THIN_ARCHIVES has been available for a while as an optional feature
only for PowerPC architecture, but we do not need two different

various advantages:- save disk space for builds
- speed-up building a little
- fix some link issues (for example, allyesconfig on ARM) due to more
flexibility for the final linking- work better with dead code elimination we are planning

The thin archives build currently puts all lib.a and built-in.o
files together and links them with --whole-archive.This works because thin archives can recursively refer to thin
archives. However some architectures include libgcc.a, which may
not be a thin archive, or it may not be constructed with the "P"
option, in which case its contents do not get linked correctly.So don't pull .a libs into the root built-in.o archive. These
libs should already have symbol tables and indexes built, so they
can be direct linker inputs. Move them out of the --whole-archive
option, which restore the conditional linking behaviour of lib.a
to thin archives builds.Signed-off-by: Nicholas Piggin

Originally, generated-y and genhdr-y had different meaning, like
follows:- generated-y: generated headers (other than asm-generic wrappers)
- header-y : headers to be exported
- genhdr-y : generated headers to be exported (generated-y + header-y)Since commit fcc8487d477a ("uapi: export all headers under uapi
directories"), headers under UAPI directories are all exported.
So, there is no more difference between generated-y and genhdr-y.We see two users of genhdr-y, arch/{arm,x86}/include/uapi/asm/Kbuild.
They generate some headers in arch/{arm,x86}/include/generated/uapi/asm
directories, which are obviously exported.Replace them with generated-y, and abolish genhdr-y.

This patch removes the need of subdir-y. Now all files/directories under
arch//include/uapi/ are exported.The only change for userland is the layout of the command 'make
headers_install_all': directories asm- are replaced by arch-/.
Those new directories contains all files/directories of the specified arch.Note that only cris and tile have more directories than only asm:
- arch-v[10|32] for cris;
- arch for tile.Signed-off-by: Nicolas Dichtel

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

The "imply" keyword is a weak version of "select" where the target
config symbol can still be turned off, avoiding those pitfalls that come
with the "select" keyword.This is useful e.g. with multiple drivers that want to indicate their
ability to hook into a secondary subsystem while allowing the user to
configure that subsystem out without also having to unset these drivers.Currently, the same effect can almost be achieved with:
config DRIVER_A
tristateconfig DRIVER_B
tristateconfig DRIVER_C
tristateconfig DRIVER_D
tristate[...]
config SUBSYSTEM_X
tristate
default DRIVER_A || DRIVER_B || DRIVER_C || DRIVER_D || [...]This is unwieldy to maintain especially with a large number of drivers.
Furthermore, there is no easy way to restrict the choice for SUBSYSTEM_X
to y or n, excluding m, when some drivers are built-in. The "select"
keyword allows for excluding m, but it excludes n as well. Hence
this "imply" keyword. The above becomes:config DRIVER_A
tristate
imply SUBSYSTEM_Xconfig DRIVER_B
tristate
imply SUBSYSTEM_X[...]
config SUBSYSTEM_X
tristateThis is much cleaner, and way more flexible than "select". SUBSYSTEM_X
can still be configured out, and it can be set as a module when none of
the drivers are configured in or all of them are modular.Signed-off-by: Nicolas Pitre

Track generated header files which aren't already in genhdr-y, alongside
generic-y wrappers in the */include/generated/[uapi/]asm/ directories.
Currently only x86 generates extra headers in these directories, for the
purposes of enumerating system calls for different ABIs, and xen
hypercalls.This will allow the asm-generic wrapper handling code to remove stale
wrappers when files are removed from generic-y, without also removing
these headers which are generated separately.Reported-by: kbuild test robot

"make allnoconfig" exists to ease testing of minimal configurations.
Documentation/SubmitChecklist includes a note to test with allnoconfig.
This helps catch missing dependencies on common-but-not-required
functionality, which might otherwise go unnoticed.However, allnoconfig still leaves many symbols enabled, because they're
hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig
still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't
typically get build-tested with those disabled.To address this, introduce a new Kconfig option "allnoconfig_y", used on
symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED
(which then selects CONFIG_EXPERT). allnoconfig will then disable all the
symbols hidden behind those.Signed-off-by: Josh Triplett
