Subject: [PATCH v2 12/24] asm-generic: Remove COMMAND_LINE_SIZE from uapi
Date: Sat, 10 Dec 2022 22:13:46 -0800	[thread overview]
Message-ID: <20221211061358.28035-13-palmer@rivosinc.com> (raw)
In-Reply-To: <20221211061358.28035-1-palmer@rivosinc.com>

From: Palmer Dabbelt <palmerdabbelt@google.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.

The various empty <uapi/asm/setup.h> will soon be removed.
