Currently, record_relative_base() iterates over the entire table to
find the minimum address, but it is not efficient because we sort
the table anyway.
After sort_symbol(), the table is sorted by address. (kallsyms parses
the 'nm -n' output, so the data is already sorted by address, but this
commit does not rely on it.)
Move record_relative_base() after sort_symbols(), and take the first

When 'exported twice' is warned, let sym_add_exported() return without

Now that there is no overwrap between symbols from ELF files and
ones from Module.symvers.
So, the 'exported twice' warning should be reported irrespective
of where the symbol in question came from.
The exceptional case is external module; in some cases, we build
an external module to provide a different version/variant of the
corresponding in-kernel module, overriding the same set of exported
symbols.
You can see this use-case in upstream; tools/testing/nvdimm/libnvdimm.ko
replaces drivers/nvdimm/libnvdimm.ko in order to link it against mocked
version of core kernel symbols.
So, let's relax the 'exported twice' warning when building external
modules. The multiple export from external modules is warned only
when the previous one is from vmlinux or itself.
With this refactoring, the ugly preloading goes away.

It is complicated to add mocked-up symbols for pre-handling CRC.
Handle CRC after all the export symbols in the relevant module
are registered.
Call handle_modversion() after the handle_symbol() iteration.
In some cases, I see atand-alone __crc_* without __ksymtab_*.
For example, ARCH=arm allyesconfig produces __crc_ccitt_veneer and
__crc_itu_t_veneer. I guess they come from crc_ccitt, crc_itu_t,
respectively. Since __*_veneer are auto-generated symbols, just
ignore them.

The incremental build of Linux kernel is pretty slow when lots of
objects are compiled. The rebuild of allmodconfig may take a few
minutes even when none of the objects needs to be rebuilt.
The time-consuming part in the incremental build is the evaluation of
if_changed* macros since they are used in the recipes to compile C and
assembly source files into objects.
I notice the following code in if_changed* is expensive:
$(filter-out $(PHONY) $(wildcard $^),$^)
In the incremental build, every object has its .*.cmd file, which
contains the auto-generated list of included headers. So, $^ are
expanded into the long list of the source file + included headers,
and $(wildcard $^) checks whether they exist.
It may not be clear why this check exists there.
Here is the record of my research.
[1] The first code addition into Kbuild
This code dates back to 2002. It is the pre-git era. So, I copy-pasted
it from the historical git tree.

The "No rule to make <file> ..." error can be solved by passing -MP to
the compiler, but I think the detection of header removal is a good
feature. When a header is removed, all source files that previously
included it should be re-compiled. This makes sure we has correctly
got rid of #include directives of it.
This is also related with the behavior of $?. The GNU Make manual says:
$?
The names of all the prerequisites that are newer than the target,
with spaces between them.
This does not explain whether a non-existent prerequisite is considered
to be newer than the target.
At this point of time, GNU Make 3.7x was used, where the $? did not
include non-existent prerequisites. Therefore,
$(filter-out FORCE $(wildcard $^),$^)
was useful to detect the header removal, and to rebuild the related
objects if it is the case.
[2] Change of $? behavior
Later, the behavior of $? was changed (fixed) to include prerequisites
that did not exist.
First, GNU Make commit 64e16d6c00a5 ("Various changes getting ready for
the release of 3.81.") changed it, but in the release test of 3.81, it
turned out to break the kernel build.
See these:
- http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html
- https://savannah.gnu.org/bugs/?16002
- https://savannah.gnu.org/bugs/?16051
Then, GNU Make commit 6d8d9b74d9c5 ("Numerous updates to tests for
issues found on Cygwin and Windows.") reverted it for the 3.81 release
to give Linux kernel time to adjust to the new behavior.
After the 3.81 release, GNU Make commit 7595f38f62af ("Fixed a number
of documentation bugs, plus some build/install issues:") re-added it.
[3] Adjustment to the new $? behavior on Kbuild side
Meanwhile, the kernel build was changed by commit 4f1933620f ("kbuild:
change kbuild to not rely on incorrect GNU make behavior") to adjust to
the new $? behavior.
[4] GNU Make 3.82 released in 2010
GNU Make 3.82 was the first release that integrated the correct $?
behavior. At this point, Kbuild dealt with GNU Make versions with
different $? behaviors.
3.81 or older:
$? does not contain any non-existent prerequisite.
$(filter-out $(PHONY) $(wildcard $^),$^) was useful to detect
removed include headers.
3.82 or newer:
$? contains non-existent prerequisites. When a header is removed,
it appears in $?. $(filter-out $(PHONY) $(wildcard $^),$^) became
a redundant check.
With the correct $? behavior, we could have dropped the expensive
check for 3.82 or later, but we did not. (Maybe nobody noticed this
optimization.)
[5] The .SECONDARY special target trips up $?
Some time later, I noticed $? did not work as expected under some
circumstances. As above, $? should contain non-existent prerequisites,
but the ones specified as SECONDARY do not appear in $?.
I asked this in GNU Make ML, and it seems a bug:
https://lists.gnu.org/archive/html/bug-make/2019-01/msg00001.html
Since commit 8e9b61b293 ("kbuild: move .SECONDARY special target to
Kbuild.include"), all files, including headers listed in .*.cmd files,
are treated as secondary.
So, we are back into the incorrect $? behavior.
If we Kbuild want to react to the header removal, we need to keep
$(filter-out $(PHONY) $(wildcard $^),$^) but this makes the rebuild
so slow.
[Summary]
- I believe noticing the header removal and recompiling related objects
is a nice feature for the build system.
- If $? worked correctly, $(filter-out $(PHONY),$?) would be enough
to detect the header removal.
- Currently, $? does not work correctly when used with .SECONDARY,
and Kbuild is hit by this bug.
- I filed a bug report for this, but not fixed yet as of writing.
- Currently, the header removal is detected by the following expensive
code:
$(filter-out $(PHONY) $(wildcard $^),$^)
- I do not want to revert commit 8e9b61b293 ("kbuild: move
.SECONDARY special target to Kbuild.include"). Specifying
.SECONDARY globally is clean, and it matches to the Kbuild policy.
This commit proactively removes the expensive check since it makes the
incremental build faster. A downside is Kbuild will no longer be able
to notice the header removal.
You can confirm it by the full-build followed by a header removal, and
then re-build.

deal. Once the $? bug is fixed in GNU Make, everything will work fine.

The modpost, with the -d option given, generates per-module .ns_deps
files.
Kbuild generates per-module .mod files to carry module information.
This is convenient because Make handles multiple jobs in parallel
when the -j option is given.
On the other hand, the modpost always runs as a single thread.
I do not see a strong reason to produce separate .ns_deps files.
This commit changes the modpost to generate just one file,
modules.nsdeps, each line of which has the following format:
<module_name>: <list of missing namespaces>
Please note it contains *missing* namespaces instead of required ones.
So, modules.nsdeps is empty if the namespace dependency is all good.
This will work more efficiently because spatch will no longer process
already imported namespaces. I removed the '(if needed)' from the
nsdeps log since spatch is invoked only when needed.
This also solves the stale .ns_deps problem reported by Jessica Yu:

Since commit 040fcc819a ("kbuild: improved modversioning support for
external modules"), the external module build reads Module.symvers in
the directory of the module itself, then dumps symbols back into it.
It accumulates stale symbols in the file when you build an external
module incrementally.
The idea behind it was, as the commit log explained, you can copy
Modules.symvers from one module to another when you need to pass symbol
information between two modules. However, the manual copy of the file
sounds questionable to me, and containing stale symbols is a downside.
Some time later, commit 0d96fb20b7 ("kbuild: Add new Kbuild variable
KBUILD_EXTRA_SYMBOLS") introduced a saner approach.
So, this commit removes the former one. Going forward, the external
module build dumps symbols into Module.symvers to be carried via
KBUILD_EXTRA_SYMBOLS, but never reads it automatically.
With the -I option removed, there is no one to set the external_module
flag unless KBUILD_EXTRA_SYMBOLS is passed. Now the -i option does it
instead.

When building external modules, $(objtree)/Module.symvers is scanned
for symbol information of vmlinux and in-tree modules.
Additionally, vmlinux is parsed if it exists in $(objtree)/.
This is totally redundant since all the necessary information is
contained in $(objtree)/Module.symvers.
Do not parse vmlinux at all for external module builds. This makes
sense because vmlinux is deleted by 'make clean'.
'make clean' leaves all the build artifacts for building external

Pull ARM SoC fixes from Olof Johansson:
"A set of fixes that have trickled in over the last couple of weeks:
- MAINTAINER update for Cavium/Marvell ThunderX2
- stm32 tweaks to pinmux for Joystick/Camera, and RAM allocation for
CAN interfaces
- i.MX fixes for voltage regulator GPIO mappings, fixes voltage
scaling issues
- More i.MX fixes for various issues on i.MX eval boards: interrupt
storm due to u-boot leaving pins in new states, fixing power button
config, a couple of compatible-string corrections.
- Powerdown and Suspend/Resume fixes for Allwinner A83-based tablets
- A few documentation tweaks and a fix of a memory leak in the reset
subsystem"
