From: Linus Torvalds Date: Mon, 29 Jul 2024 23:34:17 +0000 (-0700) Subject: profiling: remove stale percpu flip buffer variables X-Git-Tag: v6.11-rc2~34 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=94ede2a3e913;p=thirdparty%2Fkernel%2Flinux.git 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.
