tracing: add more symbols to whitelist

Browse source

Randconfig builds show a number of cryptic build errors from
hitting undefined symbols in simple_ring_buffer.o:

make[7]: *** [/home/arnd/arm-soc/kernel/trace/Makefile:147: kernel/trace/simple_ring_buffer.o.checked] Error 1

These happen with CONFIG_TRACE_BRANCH_PROFILING, CONFIG_KASAN_HW_TAGS,
CONFIG_STACKPROTECTOR, CONFIG_DEBUG_IRQFLAGS and indirectly from WARN_ON().

Add exceptions for each one that I have hit so far on arm64, x86_64 and arm
randconfig builds.

Other architectures likely hit additional ones, so it would be nice
to produce a little more verbose output that include the name of the
missing symbols directly.
