Subject: [PATCH 0/2] Introduce macros for the offsets to reserved_pg_dir and tramp_pg_dir
Date: Tue, 2 Feb 2021 12:36:56 +0000 [thread overview]
Message-ID: <20210202123658.22308-1-joey.gouly@arm.com> (raw)
Make the offsets to reserved_pg_dir and tramp_pg_dir less fragile by
introducing macros that contain their offsets.
Also use these macros to verify the offsets at link time.
Joey Gouly (2):
arm64: vmlinux.ld.S: add assertion for reserved_pg_dir offset
arm64: vmlinux.ld.S: add assertion for tramp_pg_dir offset
