The cleanup 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 broke the oprofile configuration for MIPS by allowing oprofile support to be built for kernel models where oprofile doesn't have a chance in hell to work. Just a dependecy list on a number of architectures is - surprise - broken and should as per past discussions probably in most considered to be broken in most cases. So I introduce a dependency for the oprofile configuration on ARCH_SUPPORTS_OPROFILE. Signed-off-by: Ralf Baechle <ralf@xxxxxxxxxxxxxx> --- Since we're already in -rc4 I try to keep things minimally intrusive and use ARCH_SUPPORTS_OPROFILE only for MIPS for now instead of touching a dozen architectures. arch/mips/Kconfig | 4 ++++ kernel/Kconfig.instrumentation | 2 +- 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index 455bd1f..c6fc405 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -714,6 +714,10 @@ config ARCH_HAS_ILOG2_U64 bool default n +config ARCH_SUPPORTS_OPROFILE + bool + default y if !MIPS_MT_SMTC + config GENERIC_FIND_NEXT_BIT bool default y diff --git a/kernel/Kconfig.instrumentation b/kernel/Kconfig.instrumentation index 2ea1e34..12a9f74 100644 --- a/kernel/Kconfig.instrumentation +++ b/kernel/Kconfig.instrumentation @@ -21,7 +21,7 @@ config PROFILING config OPROFILE tristate "OProfile system profiling (EXPERIMENTAL)" depends on PROFILING - depends on (ALPHA || ARM || BLACKFIN || X86_32 || IA64 || M32R || MIPS || PARISC || PPC || S390 || SUPERH || SPARC || X86_64) && !UML + depends on (ARCH_SUPPORTS_OPROFILE || ALPHA || ARM || BLACKFIN || X86_32 || IA64 || M32R || PARISC || PPC || S390 || SUPERH || SPARC || X86_64) && !UML help OProfile is a profiling system capable of profiling the whole system, include the kernel, kernel modules, libraries,
