Subject: [PATCH v3 03/23] arm/elf: Remove needless ifdef CONFIG_MMU
Date: Fri, 11 Jun 2021 19:02:22 +0100 [thread overview]
Message-ID: <20210611180242.711399-4-dima@arista.com> (raw)
In-Reply-To: <20210611180242.711399-1-dima@arista.com>
CONFIG_VDSO depends on MMU, after removing ARCH_HAS_SETUP_ADDITIONAL_PAGES
definition, the guards are excessive.
