On other ones,\nonly a subset are available.\n\nThe purpose of this series is to refactor and enhance the\nhandling of kernel boot arguments so that every architecture can\nbenefit from all possibilities.\n\nIt is first focussed on powerpc but also extends the capability\nfor other arches.\n\nThe work has been focussed on minimising the churn in architectures\nby keeping the most commonly used namings.\n\nMain changes in V4:\n- Included patch from Daniel to replace powerpc's strcpy() by strlcpy()\n- Using strlcpy() instead of zeroing first char + strlcat() (idea taken frm Daniel's series)\n- Reworked the convertion of EFI which was wrong in V3\n- Added \"too long\" command line handling\n- Changed cmdline macro into a function\n- Done a few fixes in arch (NIOS2, SH, ARM)\n- Taken comments into account (see individual responses for details)\n- Tested on powerpc, build tested on ARM64, X86_64.\n\nMain changes in V3:\n- 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.\n- Taken comments received from Will and Rob\n- Converted all architectures (Only tested on powerpc)\n\nChristophe Leroy (19):\n cmdline: Add generic function to build command line.\n drivers: of: use cmdline building function\n x86/efi: Replace CONFIG_CMDLINE_OVERRIDE by CONFIG_CMDLINE_FORCE\n drivers: firmware: efi: use cmdline building function\n cmdline: Gives architectures opportunity to use generically defined\n boot cmdline manipulation\n powerpc: Convert to GENERIC_CMDLINE\n arm: Convert to GENERIC_CMDLINE\n arm64: Convert to GENERIC_CMDLINE\n hexagon: Convert to GENERIC_CMDLINE\n microblaze: Convert to GENERIC_CMDLINE\n nios2: Convert to GENERIC_CMDLINE\n openrisc: Convert to GENERIC_CMDLINE\n riscv: Convert to GENERIC_CMDLINE\n sh: Convert to GENERIC_CMDLINE\n sparc: Convert to GENERIC_CMDLINE\n xtensa: Convert to GENERIC_CMDLINE\n x86: Convert to GENERIC_CMDLINE\n mips: Convert to GENERIC_CMDLINE\n cmdline: Remove CONFIG_CMDLINE_EXTEND\n\nDaniel Walker (1):\n powerpc: convert strcpy to strlcpy in prom_init\n\n arch/arm/Kconfig
