Subject: scripts/mksysmap: Ignore __pi_ local arm64 symbols
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=200dd957a7a72278363a8f2a49d2e90491bdb1b4;p=linux.git

scripts/mksysmap: Ignore __pi_ local arm64 symbols

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.
