This if_change_rule is not working properly; it cannot detect any
command line change.The reason is because cmd-check in scripts/Kbuild.include compares
$(cmd_$@) and $(cmd_$1), but cmd_dtc_dt_yaml does not exist here.For if_change_rule to work properly, the stem part of cmd_* and rule_*
must match. Because this cmd_and_fixdep invokes cmd_dtc, this rule must
be named rule_dtc.Fixes: 4f0e3a57d6eb ("kbuild: Add support for DT binding schema checks")

Recently, I found that get_maintainer was causing me to send emails to
the old addresses for maintainers. Since I usually just trust the
output of get_maintainer to know the right email address, I didn't even
look carefully and fired off two patch series that went to the wrong
place. Oops.The problem was introduced recently when trying to add signatures from
Fixes. The problem was that these email addresses were added too early
in the process of compiling our list of places to send. Things added to
the list earlier are considered more canonical and when we later added
maintainer entries we ended up deduplicating to the old address.Here are two examples using mainline commits (to make it easier to
replicate) for the two maintainers that I messed up recently:$ git format-patch d8549bcd0529~..d8549bcd0529
$ ./scripts/get_maintainer.pl 0001-clk-Add-clk_hw*.patch | grep Boyd
Stephen Boyd ...$ git format-patch 6d1238aa3395~..6d1238aa3395
$ ./scripts/get_maintainer.pl 0001-arm64-dts-qcom-qcs404*.patch | grep Andy
Andy GrossLet's move the adding of addresses from Fixes: to the end since the
email addresses from these are much more likely to be older.After this patch the above examples get the right addresses for the two
examples.Link: http://lkml.kernel.org/r/20200127095001.1.I41fba9f33590bfd92cd01960161d8384268c6569@changeid

Since commit 56d589361572 ("kbuild: do not create orphan built-in.a or
obj-y objects"), scripts/link-vmlinux.sh does nothing when descending
into init/.Once the version number becomes out of sync between .version and
include/generated/compile.h, it is not self-healing.[How to reproduce]
$ echo 100 > .version
$ makeYou will see the number in the .version is always bigger than that in
compile.h by one. After this, every time you run 'make', the vmlinux is
re-linked even when none of source files is updated.Fixes: 56d589361572 ("kbuild: do not create orphan built-in.a or obj-y objects")

When using a non-release version of Sphinx, from a local build (with
improvements for kernel doc handling, why not),sphinx-build --version
reports versions of the form
sphinx-build 3.0.0+/4703d9119972
i.e. base version, a plus symbol, slash, and the start of the git hash
of whatever repository the command is run in (no, not the hash that
was used to build Sphinx!).This patch fixes the installation check in sphinx-pre-install to
recognise such version output.Signed-off-by: Stephen Kitt

The symbol table is extended every 10000 addition by using realloc(),
where data copy might occur to the new buffer.To decrease the amount of possible data copy, let's change the table

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.This commit renames like follows:
always -> always-y
hostprogs-y -> hostprogsSo, scripts/Makefile will look like this:
always-$(CONFIG_BUILD_BIN2C) += ...
always-$(CONFIG_KALLSYMS) += ...
...
hostprogs := $(always-y) $(always-m)I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.Signed-off-by: Masahiro Yamada

Running randconfig on arm64 using KCONFIG_SEED=0x40C5E904 (e.g. on v5.5)
produces the .config with CONFIG_EFI=y and CONFIG_CPU_BIG_ENDIAN=y,
which does not meet the !CONFIG_CPU_BIG_ENDIAN dependency.This is because the user choice for CONFIG_CPU_LITTLE_ENDIAN vs
CONFIG_CPU_BIG_ENDIAN is set by randomize_choice_values() after the
value of CONFIG_EFI is calculated.When this happens, the has_changed flag should be set.
Currently, it takes the result from the last iteration. It should
accumulate all the results of the loop.Fixes: 3b9a19e08960 ("kconfig: loop as long as we changed some symbols in randconfig")

the crng once all CPUs have come online.- Advertise a bunch of new instructions to userspace, including
support for Data Gathering Hint, Matrix Multiply and 16-bit
floating point.Kexec:
- Cleanups in preparation for relocating with the MMU enabled
- Support for loading crash dump kernels with kexec_file_load()
Perf and PMU drivers:
- Cleanups and non-critical fixes for a couple of system PMU drivers
FPU-less (aka broken) CPU support:
- Considerable fixes to support CPUs without the FP/SIMD extensions,
including their presence in heterogeneous systems. Good luck
finding a 64-bit userspace that handles this.Modern assembly function annotations:
- Start migrating our use of ENTRY() and ENDPROC() over to the
new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended
to aid debuggersKbuild:
- Cleanup detection of LSE support in the assembler by introducing
'as-instr'- Remove compressed Image files when building clean targets
IP checksumming:
- Implement optimised IPv4 checksumming routine when hardware offload
is not in use. An IPv6 version is in the works, pending testing.Hardware errata:
- Work around Cortex-A55 erratum #1530923
Shadow call stack:
- Work around some issues with Clang's integrated assembler not
liking our perfectly reasonable assembly code- Avoid allocating the X18 register, so that it can be used to hold
the shadow call stack pointer in futureACPI:
- Fix ID count checking in IORT code. This may regress broken
firmware that happened to work with the old implementation, in
which case we'll have to revert it and try something else- Fix DAIF corruption on return from GHES handler with pseudo-NMIs
Miscellaneous:
- Whitelist some CPUs that are unaffected by Spectre-v2
- Reduce frequency of ASID rollover when KPTI is compiled in but
inactive- Reserve a couple of arch-specific PROT flags that are already used
by Sparc and PowerPC and are planned for later use with BTI on
arm64- Preparatory cleanup of our entry assembly code in preparation for
moving more of it into C later on- Refactoring and cleanup"
