Subject: [PATCH v3 12/24] asm-generic: Remove COMMAND_LINE_SIZE from uapi
Date:   Tue, 14 Feb 2023 08:49:13 +0100

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.
