Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files. Previous Kconfig sync was done by commitbf7ab1e70f
("kconfig: re-sync with Linux 4.10") and it achieved almost perfect alignment with a few (intended) exceptions, caused by below U-boot commits: [A] v2015.045f9eb22075
("kbuild: remove scripts/multiconfig.sh") [B] v2015.0720c20826ef
("Kconfig: Enable usage of escape char '\' in string values") [C] v2016.01da58dec866
("Various Makefiles: Add SPDX-License-Identifier tags") [D] v2016.035b8031ccb4
("Add more SPDX-License-Identifier tags") [E] v2016.03192bc6948b
("Fix GCC format-security errors and convert sprintfs.") Here is the list of Kconfig commits which followed the v4.10 alignment: [F] v2018.010931ed3c0d
("kconfig/symbol.c: use correct pointer type argument for sizeof") [G] v2018.031414e09b4f
("kconfig: revert change that was not needed for -Wformat-security") [H] v2018.0583d290c56f
("SPDX: Convert all of our single license tags to Linux Kernel style") Commit [F] was subsequently applied to Linux kernel as commit [I] with the same patch id, so it won't contribute to further misalignment. [I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof") Commit [G] is a Kconfig-specific revert of commit [E]. Commit [H] relocated and reformatted the license doing no functional change. In summary, the only functional change that makes U-boot Kconfig diverge from Linux Kconfig is commit [B]. After a brief analysis, the purpose of [B] seems to be placing "\n" literals in string symbols like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass them directly to printf and expect correct output at runtime. Currently, Linux doesn't seem to have this requirement, so for the moment [B] looks like a U-boot specific feature/fix. From point of view of further Kconfig alignment and backporting efforts, it is highly desired that commits like [B] are propagated to Linux and any Kconfig fixes/features are contributed to Linux kernel first. This specific Kconfig re-sync just keeps [B] in place. Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig changes), 4.17-rc4 re-sync does some amount of updates in Kbuild (striving to keep them at minimum), due to a number of reasons: * Kbuild is affected by the removal of Kconfig "*shipped" files and now requires flex and bison pre-installed on the host. * PYTHON{2,3} variables are defined in top-level Makefile as prerequisite for running the newly developed Kconfig unit tests. * silentoldconfig becomes an "internal implementation detail" deprecated for external use, being renamed to syncconfig. The exact non-kconfig files touched by this commit are: $ git show --format="" --stat -- ':!scripts/kconfig' .gitignore | 2 ++ Makefile | 9 +++++++-- scripts/Makefile.build | 11 +++++++++++ scripts/Makefile.lib | 41 ++++++++++++----------------------------- The imported Linux commits touching the above files are: c054be10ffdbd5 ("remove gperf left-overs from build system") 73a4f6dbe70a1b ("kbuild: add LEX and YACC variables") 033dba2ec06c47 ("kbuild: prepare to remove C files pre-generated by flex and bison") eea199b445f64c ("kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX") e71de5ee08dcb0 ("kbuild: remove remaining use of undefined YACC_PREFIX") d59fbbd09d5d6b ("kbuild: replace hardcoded bison in cmd_bison_h with $(YACC)") 911a91c39cabcb H ("kconfig: rename silentoldconfig to syncconfig") 59889300274569 (".gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore") 9a8dfb394c0467 ("kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile") 833e622459432e H ("genksyms: generate lexer and parser during build instead of shipping") b23d1a241f4eb4 H ("kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically") e9781b52d4e0e3 H ("kbuild: add PYTHON2 and PYTHON3 variables") The commits marked with 'H' are assessed as "hard" (build will fail) prerequisites and the rest of them are assessed as "soft" prerequisites for the re-sync. In spite of relatively high number of non-H commits, they belong to this Kconfig update topic-wise and decrease the number of cherry pick conflicts for many commits in this series. Additional effort can be put in eliminating the soft prerequisites, if really needed. The commits which contributed to this Kconfig re-sync are listed below. Whenever a conflict resolution has been performed (mostly by hand, but sometimes automatically by git), it is revealed by the '!' sign in the second column, which means a patch id mismatch between Linux and U-boot commits: 9be3213b14d44f ("gconfig: remove misleading parentheses around a condition") ff85a1a80e0034 ("kconfig: Check for libncurses before menuconfig") ad8181060788c8 ("kconfig: fix sparse warnings in nconfig") cb77f0d623ff33 !

("kbuild: add PYTHON2 and PYTHON3 variables") The current Kconfig update generates below build-time warnings: YACC scripts/dtc/dtc-parser.tab.h scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr] YACC scripts/dtc/dtc-parser.tab.c scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr] This seems to happen because the Kbuild updates apparently didn't make room for both "*shipped"-based builds and flex/bison-based builds. A similar problem has been reported for genksyms parser in v4.17-rc1 commit 833e622459432e ("genksyms: generate lexer and parser during build instead of shipping"). I have figured out empirically that the warnings are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9, same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the DTC-related yacc warnings should be done together with the Kconfig re-sync, I would like to hear from community. My testing was limited to: - make defconfig all - make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- r8a7795_ulcb_defconfig all - comparing .config before and after the re-sync - running the newly imported Kconfig unit tests as seen below: $ make testconfig Tested-by: Petr Vorel <petr.vorel@gmail.com> ============================= test session starts ============================= scripts/kconfig/tests/auto_submenu/__init__.py::test PASSED [ 7%] scripts/kconfig/tests/choice/__init__.py::test_oldask0 PASSED [ 14%] scripts/kconfig/tests/choice/__init__.py::test_oldask1 PASSED [ 21%] scripts/kconfig/tests/choice/__init__.py::test_allyes PASSED [ 28%] scripts/kconfig/tests/choice/__init__.py::test_allmod PASSED [ 35%] scripts/kconfig/tests/choice/__init__.py::test_allno PASSED [ 42%] scripts/kconfig/tests/choice/__init__.py::test_alldef PASSED [ 50%] scripts/kconfig/tests/choice_value_with_m_dep/__init__.py::test PASSED [ 57%] scripts/kconfig/tests/err_recursive_inc/__init__.py::test PASSED [ 64%] scripts/kconfig/tests/inter_choice/__init__.py::test PASSED [ 71%] scripts/kconfig/tests/new_choice_with_dep/__init__.py::test PASSED [ 78%] scripts/kconfig/tests/no_write_if_dep_unmet/__init__.py::test PASSED [ 85%] scripts/kconfig/tests/rand_nested_choice/__init__.py::test PASSED [ 92%] scripts/kconfig/tests/warn_recursive_dep/__init__.py::test PASSED [100%] ========================== 14 passed in 0.34 seconds ========================== Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Masahiro Yamada <yamada.masahiro@socionext.com> Tested-by: Petr Vorel <petr.vorel@gmail.com>
