Subject: [RFC PATCH v1 02/19] powerpc/ptrace: Move declaration of ptrace_get_reg() and ptrace_set_reg()
Date: Wed, 12 Aug 2020 12:05:53 +0000 (UTC)	[thread overview]
Message-ID: <6b590dfd8f7e5d7cbe08efd376ac056cefc5aba7.1597233555.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1597233555.git.christophe.leroy@csgroup.eu>

ptrace_get_reg() and ptrace_set_reg() are only used internally by
ptrace.

Move them in arch/powerpc/kernel/ptrace/ptrace-decl.h
