Subject: [PATCH v5 13/26] asm-generic: Remove COMMAND_LINE_SIZE from uapi
From: Palmer Dabbelt <palmerdabbelt@...gle.com>
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.
