The quilt patch titled Subject: mips: smp: fix setup_profiling_timer() prototype has been removed from the -mm tree. Its filename was mips-smp-fix-setup_profiling_timer-prototype.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: mips: smp: fix setup_profiling_timer() prototype Date: Mon, 4 Dec 2023 12:57:09 +0100 The function is unconditionally defined in smp.c but is conditionally declared in a header that is not included here. arch/mips/kernel/smp.c:473:5: error: no previous prototype for 'setup_profiling_timer' [-Werror=missing-prototypes] Add the missing #include and #ifdef to match the declaration.
