Subject: [PATCH v2 5/7] kexec_elf: remove elf_addr_to_cpu macro
Date: Tue, 9 Jul 2019 21:43:26 +0200 [thread overview]
Message-ID: <20190709194328.16991-6-svens@stackframe.org> (raw)
In-Reply-To: <20190709194328.16991-1-svens@stackframe.org>
It had only one definition, so just use the function directly.
