Subject: [PATCH] scripts/mksysmap: Ignore __pi_ local arm64 symbols
Date: Tue, 6 Jun 2023 18:19:36 +0000 [thread overview]
Message-ID: <20230606181936.bw62oyqswo7jomra@google.com> (raw)
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.
