Subject: [PATCH] scripts/mksysmap: Ignore __pi_ local arm64 symbols
Message-ID: <20230606181936.bw62oyqswo7jomra@google.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Disposition: inline
Content-Transfer-Encoding: 8bit
Precedence: bulk

Similarly to "__kvm_nvhe_", filter out any local symbol that was
prefixed with "__pi_" (generated when CONFIG_RANDOMIZE_BASE=y) when
compiling System.map and in kallsyms.
