Reworked in V4.
The purpose of this series is to improve and enhance the handling of kernel boot arguments. It is first focussed on powerpc but also extends the capability for other arches. This is based on suggestion from Daniel Walker <danielwa@cisco.com> Main changes in V3: - Also accept destination equal to source in cmdline_build() by setting a tmp buffer in __initdata. Powerpc provides different source and destination and call __cmdline_build() directly. - Taken comments received from Will and Rob - Converted all architectures (Only tested on powerpc) Christophe Leroy (17): cmdline: Add generic function to build command line. drivers: of: use cmdline building function cmdline: Gives architectures opportunity to use generically defined boot cmdline manipulation powerpc: Convert to GENERIC_CMDLINE arm: Convert to GENERIC_CMDLINE arm64: Convert to GENERIC_CMDLINE hexagon: Convert to GENERIC_CMDLINE microblaze: Convert to GENERIC_CMDLINE nios2: Convert to GENERIC_CMDLINE openrisc: Convert to GENERIC_CMDLINE riscv: Convert to GENERIC_CMDLINE sh: Convert to GENERIC_CMDLINE sparc: Convert to GENERIC_CMDLINE xtensa: Convert to GENERIC_CMDLINE x86: Convert to GENERIC_CMDLINE mips: Convert to GENERIC_CMDLINE cmdline: Remove CONFIG_CMDLINE_EXTEND arch/arm/Kconfig | 38 +------------- arch/arm/kernel/atags_parse.c | 15 ++---- arch/arm64/Kconfig | 33 +----------- arch/arm64/kernel/idreg-override.c | 9 ++-- arch/hexagon/Kconfig | 11 +--- arch/hexagon/kernel/setup.c | 10 +--- arch/microblaze/Kconfig | 24 +-------- arch/microblaze/configs/mmu_defconfig | 2 +- arch/microblaze/kernel/head.S | 4 +- arch/mips/Kconfig | 1 + arch/mips/Kconfig.debug | 44 ---------------- arch/mips/configs/ar7_defconfig | 1 - arch/mips/configs/bcm47xx_defconfig | 1 - arch/mips/configs/bcm63xx_defconfig | 1 - arch/mips/configs/bmips_be_defconfig | 1 - arch/mips/configs/bmips_stb_defconfig | 1 - arch/mips/configs/capcella_defconfig | 1 - arch/mips/configs/ci20_defconfig | 1 - arch/mips/configs/cu1000-neo_defconfig | 1 - arch/mips/configs/cu1830-neo_defconfig | 1 - arch/mips/configs/e55_defconfig | 1 - arch/mips/configs/generic_defconfig | 1 - arch/mips/configs/gpr_defconfig | 1 - arch/mips/configs/loongson3_defconfig | 1 - arch/mips/configs/mpc30x_defconfig | 1 - arch/mips/configs/rt305x_defconfig | 1 - arch/mips/configs/tb0219_defconfig | 1 - arch/mips/configs/tb0226_defconfig | 1 - arch/mips/configs/tb0287_defconfig | 1 - arch/mips/configs/workpad_defconfig | 1 - arch/mips/configs/xway_defconfig | 1 - arch/mips/kernel/relocate.c | 4 +- arch/mips/kernel/setup.c | 40 +-------------- arch/mips/pic32/pic32mzda/early_console.c | 2 +- arch/mips/pic32/pic32mzda/init.c | 2 - arch/nios2/Kconfig | 24 +-------- arch/nios2/kernel/setup.c | 13 ++--- arch/openrisc/Kconfig | 10 +--- arch/powerpc/Kconfig | 37 +------------ arch/powerpc/kernel/prom_init.c | 17 +++--- arch/riscv/Kconfig | 44 +--------------- arch/riscv/kernel/setup.c | 5 +- arch/sh/Kconfig | 30 +---------- arch/sh/configs/ap325rxa_defconfig | 2 +- arch/sh/configs/dreamcast_defconfig | 2 +- arch/sh/configs/ecovec24-romimage_defconfig | 2 +- arch/sh/configs/ecovec24_defconfig | 2 +- arch/sh/configs/edosk7760_defconfig | 2 +- arch/sh/configs/espt_defconfig | 2 +- arch/sh/configs/j2_defconfig | 2 +- arch/sh/configs/kfr2r09-romimage_defconfig | 2 +- arch/sh/configs/kfr2r09_defconfig | 2 +- arch/sh/configs/lboxre2_defconfig | 2 +- arch/sh/configs/microdev_defconfig | 2 +- arch/sh/configs/migor_defconfig | 2 +- arch/sh/configs/polaris_defconfig | 2 +- arch/sh/configs/r7780mp_defconfig | 2 +- arch/sh/configs/r7785rp_defconfig | 2 +- arch/sh/configs/rsk7201_defconfig | 2 +- arch/sh/configs/rsk7203_defconfig | 2 +- arch/sh/configs/rts7751r2d1_defconfig | 2 +- arch/sh/configs/rts7751r2dplus_defconfig | 2 +- arch/sh/configs/sdk7780_defconfig | 2 +- arch/sh/configs/sdk7786_defconfig | 2 +- arch/sh/configs/se7206_defconfig | 2 +- arch/sh/configs/se7343_defconfig | 2 +- arch/sh/configs/se7712_defconfig | 2 +- arch/sh/configs/se7721_defconfig | 2 +- arch/sh/configs/se7724_defconfig | 2 +- arch/sh/configs/se7751_defconfig | 2 +- arch/sh/configs/se7780_defconfig | 2 +- arch/sh/configs/sh03_defconfig | 2 +- arch/sh/configs/sh2007_defconfig | 2 +- arch/sh/configs/sh7757lcr_defconfig | 2 +- arch/sh/configs/sh7763rdp_defconfig | 2 +- arch/sh/configs/shmin_defconfig | 2 +- arch/sh/configs/shx3_defconfig | 2 +- arch/sh/configs/titan_defconfig | 2 +- arch/sh/configs/ul2_defconfig | 2 +- arch/sh/kernel/setup.c | 11 +--- arch/sparc/Kconfig | 18 +------ arch/sparc/prom/bootstr_64.c | 2 +- arch/x86/Kconfig | 45 +--------------- arch/x86/kernel/setup.c | 17 +----- arch/xtensa/Kconfig | 15 +----- arch/xtensa/configs/audio_kc705_defconfig | 1 - arch/xtensa/configs/common_defconfig | 1 - arch/xtensa/configs/generic_kc705_defconfig | 1 - arch/xtensa/configs/iss_defconfig | 1 - arch/xtensa/configs/nommu_kc705_defconfig | 1 - arch/xtensa/configs/smp_lx200_defconfig | 1 - arch/xtensa/configs/virt_defconfig | 1 - arch/xtensa/configs/xip_kc705_defconfig | 1 - arch/xtensa/kernel/setup.c | 10 +--- drivers/firmware/efi/libstub/x86-stub.c | 26 +++++----- drivers/of/fdt.c | 23 ++------- include/linux/cmdline.h | 57 +++++++++++++++++++++ init/Kconfig | 46 +++++++++++++++++ 98 files changed, 209 insertions(+), 580 deletions(-) create mode 100644 include/linux/cmdline.h
