From: Andi Kleen <ak@linux.intel.com>
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.
