Subject: [PATCH v2 6/6] RISC-V: Move dynamic relocation section under __init
Date: Mon, 26 Oct 2020 16:02:54 -0700	[thread overview]
Message-ID: <20201026230254.911912-7-atish.patra@wdc.com> (raw)
In-Reply-To: <20201026230254.911912-1-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.
