Subject: [PATCH 2/2] riscv: mm: use __pa_symbol for kernel symbols
Date: Thu, 2 Jan 2020 11:12:40 +0800 [thread overview]
Message-ID: <20200102031240.44484-3-zong.li@sifive.com> (raw)
In-Reply-To: <20200102031240.44484-1-zong.li@sifive.com>
__pa_symbol is the marcro that should be used for kernel symbols. It is
also a pre-requisite for DEBUG_VIRTUAL which will do bounds checking.
