Update the files under scripts/kconfig/ to match Linux 4.1. Some Kconfig sources have diverged from those in the kernel, so commit-base syncing was done not to lose U-Boot specific updates. The commits cherry-picked from Linux are: [1] commit be8af2d54a66911693eddc556e4f7a866670082b Author: Bjørn Forsman <bjorn.forsman@gmail.com> kconfig/lxdialog: get ncurses CFLAGS with pkg-config [2] commit 3943f42c11896ce82ad3da132c8a5630313bdd0e Author: Andrey Utkin <andrey.krieger.utkin@gmail.com> Replace mentions of "list_struct" to "list_head" [3] commit e4e458b45c5861808674eebfea94cee2258bb2ea Author: Arjun Sreedharan <arjun024@gmail.com> calloc/xcalloc: Fix argument order [4] commit 09950bc256e3628d275f90e016e6f5a039fbdcab Author: Olof Johansson <olof@lixom.net> merge_config.sh: Display usage if given too few arguments [5] commit b6a2ab2cd4739a9573ed41677e53171987b8da34 Author: Colin Ian King <colin.king@canonical.com> kconfig: use va_end to match corresponding va_start [6] commit 70529b1a1784503169416df19ce3d68746401340 Author: Michal Marek <mmarek@suse.cz> kconfig: Get rid of the P() macro in headers [7] commit 463157444e377bf9b279101b1f16a94c4648c03a Author: Michal Marek <mmarek@suse.cz> kconfig: Remove dead code [8] commit ad8d40cda3ad22ad9e8863d55a5c88f85c0173f0 Author: Michal Marek <mmarek@suse.cz> kconfig: Remove unnecessary prototypes from headers [9] commit de4619937229378e81f95e99c9866acc8e207d34 Author: Masahiro Yamada <yamada.masahiro@socionext.com> kbuild: mergeconfig: fix "jobserver unavailable" warning [10] commit b9fe99c5b994c6ddc57780993966b18899526c0b Author: Masahiro Yamada <yamada.masahiro@socionext.com> kbuild: mergeconfig: move an error check to merge_config.sh [11] commit 371cfd4ff0611d8bc5d18bbb9cc6a2bc3d56cd3d Author: Masahiro Yamada <yamada.masahiro@socionext.com> kbuild: mergeconfig: remove redundant $(objtree) [12] commit 3a975b8cfcbe026b535f83bde9a3c009bae214f9 Author: Masahiro Yamada <yamada.masahiro@socionext.com> merge_config.sh: improve indentation [13] commit bc8f8f5fc47cd02c2c5f3580dac2fe6695af1edd Author: Masahiro Yamada <yamada.masahiro@socionext.com> merge_config.sh: rename MAKE to RUNMAKE [14] commit 63a91033d52e64a22e571fe84924c0b7f21c280d Author: Masahiro Yamada <yamada.masahiro@socionext.com> kbuild: add generic mergeconfig target, %.config [15] commit 1cba0c305758c3c1786ecaceb03e142c95a4edc9 Author: Michal Marek <mmarek@suse.cz> kconfig: Simplify Makefile [16] commit 0a1f00a1c86421cc07cec87011c7cf4df68ee54b Author: Michal Marek <mmarek@suse.cz> kconfig: Do not print status messages in make -s mode Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Bjørn Forsman <bjorn.forsman@gmail.com> Signed-off-by: Andrey Utkin <andrey.krieger.utkin@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Arjun Sreedharan <arjun024@gmail.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
