Linus Torvalds 0ad39cb3d7 Kconfig updates for v4.18 ... Kconfig now supports new functionality to perform textual substitution. It has been a while since Linus suggested to move compiler option tests from makefiles to Kconfig. Finally, here it is. The implementation has been generalized into a Make-like macro language. Some built-in functions such as 'shell' are provided. Variables and user-defined functions are also supported so that 'cc-option', 'ld-option', etc. are implemented as macros. Summary: - refactor package checks for building {m,n,q,g}conf - remove unused/unmaintained localization support - remove Kbuild cache - drop CONFIG_CROSS_COMPILE support - replace 'option env=' with direct variable expansion - add built-in functions such as 'shell' - support variables and user-defined functions - add helper macros as as 'cc-option' - add unit tests and a document of the new macro language - add 'testconfig' to help - fix warnings from GCC 8.1 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJbGBJPAAoJED2LAQed4NsG9QEP/24saP6Q3uF68yOsXcyE7yL0 VW6acNpCXFjyQZQuHB9JntD9oftSfPuY73mjVKPRvL29NopbFbe7O7wAOYSRvsZT cTZ5KF0FpG0enP6qUUiVpGZPGiSXKu21Lr/WrCdS889O2g5NxCB6OameQLjXkz5P EZb+QZD6drzYkXjipLJoliFJAhsbaACxmuCgO1gpg+qAEOm/fCnRk1qVwKffH21Z YlKMpw0FR3IdZA/cYp5Bh/WiICaCXs8lmMupHb4BHL4SvJGXxMEnuyt1txXANJcv 3nTxsMPwjdCGboEgCavbcUnTaONnFK6IdGhdSntsf1aKRqHntiA/cwqmJl2RX/6v ObX85dRjvyKq+qh9wEGvUle0LQYxhvJJ4NyWX5+wiRB6wzPCuqTPL0I1y6UPwAkQ JveUswQ7u3+dCBwuHeXFHWvpviNFkWO+Gc8E2h1PKroG0Tz3HpoQclvcZjsOXrRt HX2+6EsuYK2LnabwQzk4TRkI7JnTKpLGG/YoM4H360bNHs5KUwgm6g5V9Oo4L3E+ A5Jbow5siKtn7lIR9TXDou6O6F7L+bMiK+PlydPiv085EqUfhP+rkiJu9sb18GPD dsMXeTN51cJYLtDNiZ9tnPBtTB6Wvk7K1Dcmf3/t3rWVy35tjgl0RdxEySU153Pk n62ftyGGyUldBSzWcGWR =o37+ -----END PGP SIGNATURE----- Merge tag 'kconfig-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kconfig updates from Masahiro Yamada: "Kconfig now supports new functionality to perform textual substitution.
