Subject: [PATCH v2 2/5] entry: rename exit_from_user_mode()
Date: Tue,  1 Dec 2020 15:27:52 +0100	[thread overview]
Message-ID: <20201201142755.31931-3-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 additional exit_from_user_mode()
function will be added with a later commit.
