tracing: add more symbols to whitelist
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.
Fixes: a717943d8ecc ("tracing: Check for undefined symbols in simple_ring_buffer")
