From: Palmer Dabbelt <redacted> As far as I can tell this is not used by userspace and thus should not be part of the user-visible API. Since <uapi/asm-generic/setup.h> only contains COMMAND_LINE_SIZE we can just move it out of uapi to hide the definition and fix up the only direct use in Loongarch.

This limit depends on the architecture and is between 256 and 4096 characters. It is defined in the file -./include/uapi/asm-generic/setup.h as COMMAND_LINE_SIZE. +./include/asm-generic/setup.h as COMMAND_LINE_SIZE. Finally, the [KMG] suffix is commonly described after a number of kernel parameter values. These 'K', 'M', and 'G' letters represent the _binary_
