  As said in the help of ARCH_WANTS_NO_INSTR entry in arch/Kconfig:
"An architecture should select this if the noinstr macro is being used on
functions to denote that the toolchain should avoid instrumenting such
functions and is required for correctness."

Select ARCH_WANTS_NO_INSTR for correctness.

PS: The reason we didn't find any issue so far is that the
CC_HAS_NO_PROFILE_FN_ATTR is true.
