From: Andi Kleen <ak@xxxxxxxxxxxxxxx>
Subject: lib/Kconfig.debug: don't let LATENCYTOP and LOCKDEP select KALLSYMS_ALL
KALLSYMS_ALL enables including data variables into KALLSYMS. With plain
KALLSYMS only functions are included.
LATENCYTOP and LOCKDEP select KALLSYMS_ALL in addition to KALLSYMS. It's
unclear what they actually need _ALL for; they should only need function
backtraces and afaik never touch variables.
LTO currently does not support KALLSYMS_ALL, which prevents LATENCYTOP and
LOCKDEP from working and gives Kconfig errors. Disable the requirement
for KALLSYMS_ALL for them, just use KALLSYMS.
