#     powerpc: Don't select ARCH_WANTS_NO_INSTR
#     
#     Commit 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN
#     support") added a select of ARCH_WANTS_NO_INSTR, because it also added
#     some uses of noinstr. However noinstr is always defined, regardless of
#     ARCH_WANTS_NO_INSTR, so there's no need to select it just for that.
#     
#     As PeterZ says [1]:
#       Note that by selecting ARCH_WANTS_NO_INSTR you effectively state to
#       abide by its rules.
#     
#     As of now the powerpc code does not abide by those rules, and trips some
#     new warnings added by Peter in linux-next.
#     
#     So until the code can be fixed to avoid those warnings, disable
#     ARCH_WANTS_NO_INSTR.
#     
#     Note that ARCH_WANTS_NO_INSTR is also used to gate building KCOV and
#     parts of KCSAN. However none of the noinstr annotations in powerpc were
#     added for KCOV or KCSAN, instead instrumentation is blocked at the file
#     level using KCOV_INSTRUMENT_foo.o := n.
