Subject: [PATCH v2 1/5] entry: rename enter_from_user_mode()
Date: Tue, 1 Dec 2020 15:27:51 +0100 [thread overview]
Message-ID: <20201201142755.31931-2-svens@linux.ibm.com> (raw)
In-Reply-To: <20201201142755.31931-1-svens@linux.ibm.com>
In order to make this function publicly available rename
it so it can still be inlined. An addtional enter_from_user_mode()
function will be added with a later commit.
