Subject: [PATCH 5/5] RISC-V: Move dynamic relocation section under __init
Date: Fri, 9 Oct 2020 14:13:44 -0700 [thread overview]
Message-ID: <20201009211344.2358688-6-atish.patra@wdc.com> (raw)
In-Reply-To: <20201009211344.2358688-1-atish.patra@wdc.com>
Dynamic relocation section are only required during boot. Those sections
can be freed after init. Thus, it can be moved to __init section.
