Subject: [PATCH 1/5] RISC-V: Move __start_kernel to .head.text
Date: Fri, 9 Oct 2020 14:13:40 -0700 [thread overview]
Message-ID: <20201009211344.2358688-2-atish.patra@wdc.com> (raw)
In-Reply-To: <20201009211344.2358688-1-atish.patra@wdc.com>
Currently, __start_kernel is kept in _init while _start is in head section.
This may result in "relocation truncated to fit error" if _init section is
moved far from head. It also makes sense to keep entire head.S in one
section.
Keep __start_kernel in head section rather than _init.
