#     profiling: remove stale percpu flip buffer variables
#     
#     For some reason I didn't see this issue on my arm64 or x86-64 builds,
#     but Stephen Rothwell reports that commit 2accfdb7eff6 ("profiling:
#     attempt to remove per-cpu profile flip buffer") left these static
#     variables around, and the powerpc build is unhappy about them:
#     
#       kernel/profile.c:52:28: warning: 'cpu_profile_flip' defined but not used [-Wunused-variable]
#          52 | static DEFINE_PER_CPU(int, cpu_profile_flip);
#             |                            ^~~~~~~~~~~~~~~~
#       ..
#     
#     So remove these stale left-over remnants too.
#     
#     Fixes: 2accfdb7eff6 ("profiling: attempt to remove per-cpu profile flip buffer")
