'make clean' descends into ./Kbuild, but does not clean anything since everything is added to no-clean-files. There is no need to descend to ./Kbuild in the first place. We can drop the no-clean-files assignment. With this, there is no more user of no-clean-files. I will keep it for a while to see whether a new user will appear.

'make /' is just an alias for 'make ./'; this builds all objects of an external module, but skips the modpost stage. I am not a big fan of 'make /' since it looks as if it were touching the root directory of the system. I like 'make ./' better. I do not know how many people are using it, but let's show a hint if it is used. Also, move it close to the external module rules since this only makes sense for external modules.

For the single target building %.symtypes from %.S, $(a_flags) is expanded into the _KERNEL flags even if the object is a part of a module. $(real-obj-m:.o=.symtypes): modkern_aflags := $(KBUILD_AFLAGS_MODULE) $(AFLAGS_MODULE) ... would fix the issue, but it is not nice to duplicate similar code for every suffix. Implement modkern_aflags in the same way as modkern_cflags. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Currently, Kbuild treats an object as multi-used when any of $(foo-objs), $(foo-y), $(foo-m) is set. It makes more sense to check $(foo-) as well. In the context of foo-$(CONFIG_FOO_FEATURE1), CONFIG_FOO_FEATURE1 could be unset. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Flex and bison are used for kconfig, dtc, genksyms, all of which are host programs. I never imagine the kernel embeds a parser or a lexer. Move the flex and bison rules to scripts/Makefile.host. This file is included only when hostprogs-y etc. is present in the Makefile in the directory. So, parsing these rules are skipped in most of directories.

We generally expect bison to create not only a C file, but also a header, which will be included from the lexer. Currently, Kbuild generates them in separate rules. So, for instance, when building Kconfig, you will notice bison is invoked twice: HOSTCC scripts/kconfig/conf.o HOSTCC scripts/kconfig/confdata.o HOSTCC scripts/kconfig/expr.o LEX scripts/kconfig/lexer.lex.c YACC scripts/kconfig/parser.tab.h HOSTCC scripts/kconfig/lexer.lex.o YACC scripts/kconfig/parser.tab.c HOSTCC scripts/kconfig/parser.tab.o HOSTCC scripts/kconfig/preprocess.o HOSTCC scripts/kconfig/symbol.o HOSTLD scripts/kconfig/conf Make handles such cases nicely in pattern rules [1]. Merge the two rules so that one invokcation of bison can generate both of them. HOSTCC scripts/kconfig/conf.o HOSTCC scripts/kconfig/confdata.o HOSTCC scripts/kconfig/expr.o LEX scripts/kconfig/lexer.lex.c YACC scripts/kconfig/parser.tab.[ch] HOSTCC scripts/kconfig/lexer.lex.o HOSTCC scripts/kconfig/parser.tab.o HOSTCC scripts/kconfig/preprocess.o HOSTCC scripts/kconfig/symbol.o HOSTLD scripts/kconfig/conf [1] Pattern rule GNU Make manual says: "Pattern rules may have more than one target. Unlike normal rules, this does not act as many different rules with the same prerequisites and recipe. If a pattern rule has multiple targets, make knows that the rule's recipe is responsible for making all of the targets. The recipe is executed only once to make all the targets. When searching for a pattern rule to match a target, the target patterns of a rule other than the one that matches the target in need of a rule are incidental: make worries only about giving a recipe and prerequisites to the file presently in question. However, when this file's recipe is run, the other targets are marked as having been updated themselves." https://www.gnu.org/software/make/manual/html_node/Pattern-Intro.htmlSigned-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

$(basename ...) trims the last suffix. Using it is more intuitive in my opinion. This pattern rule makes %.asn1.c and %.asn1.h at the same time. Previously, the short log showed only either of them, depending on the target file in question. To clarify that two files are being generated by the single recipe, I changed the log as follows: Before: ASN.1 crypto/asymmetric_keys/x509.asn1.c After: ASN.1 crypto/asymmetric_keys/x509.asn1.[ch] Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

The gold linker has known issues of failing the build both in random and in predictible ways: - The x86/X32 VDSO build fails with: arch/x86/entry/vdso/vclock_gettime-x32.o:vclock_gettime.c:function do_hres: error: relocation overflow: reference to 'hvclock_page' That's a known issue for years and the usual workaround is to disable CONFIG_X86_32 - A recent build failure is caused by turning a relocation into an absolute one for unknown reasons. See link below. - There are a couple of gold workarounds applied already, but reports about broken builds with ld.gold keep coming in on a regular base and in most cases the root cause is unclear. In context of the most recent fail H.J. stated: "Since building a workable kernel for different kernel configurations isn't a requirement for gold, I don't recommend gold for kernel." So instead of dealing with attempts to duct tape gold support without understanding the root cause and without support from the gold folks, fail the build when gold is detected.

This patch adds a check to warn about static EXPORT_SYMBOL* functions during the modpost. In most of the cases, a static symbol marked for exporting is an odd combination that should be fixed either by deleting the exporting mark or by removing the static attribute and adding the appropriate declaration to headers. This check could help to detect the following problems: 1. 550113d4 ("i2c: add newly exported functions to the header, too") 2. 54638c6e ("net: phy: make exported variables non-static") 3. 98ef2046 ("mm: remove the exporting of totalram_pages") 4. 73df167c ("s390/zcrypt: remove the exporting of ap_query_configuration") 5. a57caf8c ("sunrpc/cache: remove the exporting of cache_seq_next") 6. e4e47306 ("crypto: skcipher - remove the exporting of skcipher_walk_next") 7. 14b4c48b ("gve: Remove the exporting of gve_probe") 8. 9b79ee97 ("scsi: libsas: remove the exporting of sas_wait_eh") 9. ... The build time impact is very limited and is almost at the unnoticeable level (< 1 sec).
