From 8d976d7a883cfc6bdb1199e6b6af20c211facbba Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Tue, 6 Nov 2018 19:49:34 -0600 Subject: [PATCH] KVM: PPC: Move and undef TRACE_INCLUDE_PATH/FILE [ Upstream commit 28c5bcf74fa07c25d5bd118d1271920f51ce2a98 ] TRACE_INCLUDE_PATH and TRACE_INCLUDE_FILE are used by , so like that #include, they should be outside #ifdef protection. They also need to be #undefed before defining, in case multiple trace headers are included by the same C file. This became the case on book3e after commit cf4a6085151a ("powerpc/mm: Add missing tracepoint for tlbie"), leading to the following build error: CC arch/powerpc/kvm/powerpc.o In file included from arch/powerpc/kvm/powerpc.c:51:0: arch/powerpc/kvm/trace.h:9:0: error: "TRACE_INCLUDE_PATH" redefined [-Werror] #define TRACE_INCLUDE_PATH . ^ In file included from arch/powerpc/kvm/../mm/mmu_decl.h:25:0, from arch/powerpc/kvm/powerpc.c:48: ./arch/powerpc/include/asm/trace.h:224:0: note: this is the location of the previous definition #define TRACE_INCLUDE_PATH asm ^ cc1: all warnings being treated as errors Reported-by: Christian Zigotzky Signed-off-by: Scott Wood Signed-off-by: Michael Ellerman Signed-off-by: Sasha Levin --- arch/powerpc/kvm/trace.h | 8 ++++++-- arch/powerpc/kvm/trace_booke.h | 9 +++++++-- arch/powerpc/kvm/trace_hv.h | 9 +++++++-- arch/powerpc/kvm/trace_pr.h | 9 +++++++-- 4 files changed, 27 insertions(+), 8 deletions(-) diff --git a/arch/powerpc/kvm/trace.h b/arch/powerpc/kvm/trace.h index 491b0f715d6b..ea1d7c808319 100644 --- a/arch/powerpc/kvm/trace.h +++ b/arch/powerpc/kvm/trace.h @@ -6,8 +6,6 @@ #undef TRACE_SYSTEM #define TRACE_SYSTEM kvm -#define TRACE_INCLUDE_PATH . -#define TRACE_INCLUDE_FILE trace /* * Tracepoint for guest mode entry. @@ -120,4 +118,10 @@ TRACE_EVENT(kvm_check_requests, #endif /* _TRACE_KVM_H */ /* This part must be outside protection */ +#undef TRACE_INCLUDE_PATH +#undef TRACE_INCLUDE_FILE + +#define TRACE_INCLUDE_PATH . +#define TRACE_INCLUDE_FILE trace + #include diff --git a/arch/powerpc/kvm/trace_booke.h b/arch/powerpc/kvm/trace_booke.h index ac640e81fdc5..3837842986aa 100644 --- a/arch/powerpc/kvm/trace_booke.h +++ b/arch/powerpc/kvm/trace_booke.h @@ -6,8 +6,6 @@ #undef TRACE_SYSTEM #define TRACE_SYSTEM kvm_booke -#define TRACE_INCLUDE_PATH . -#define TRACE_INCLUDE_FILE trace_booke #define kvm_trace_symbol_exit \ {0, "CRITICAL"}, \ @@ -218,4 +216,11 @@ TRACE_EVENT(kvm_booke_queue_irqprio, #endif /* This part must be outside protection */ + +#undef TRACE_INCLUDE_PATH +#undef TRACE_INCLUDE_FILE + +#define TRACE_INCLUDE_PATH . +#define TRACE_INCLUDE_FILE trace_booke + #include diff --git a/arch/powerpc/kvm/trace_hv.h b/arch/powerpc/kvm/trace_hv.h index bcfe8a987f6a..8a1e3b0047f1 100644 --- a/arch/powerpc/kvm/trace_hv.h +++ b/arch/powerpc/kvm/trace_hv.h @@ -9,8 +9,6 @@ #undef TRACE_SYSTEM #define TRACE_SYSTEM kvm_hv -#define TRACE_INCLUDE_PATH . -#define TRACE_INCLUDE_FILE trace_hv #define kvm_trace_symbol_hcall \ {H_REMOVE, "H_REMOVE"}, \ @@ -497,4 +495,11 @@ TRACE_EVENT(kvmppc_run_vcpu_exit, #endif /* _TRACE_KVM_HV_H */ /* This part must be outside protection */ + +#undef TRACE_INCLUDE_PATH +#undef TRACE_INCLUDE_FILE + +#define TRACE_INCLUDE_PATH . +#define TRACE_INCLUDE_FILE trace_hv + #include diff --git a/arch/powerpc/kvm/trace_pr.h b/arch/powerpc/kvm/trace_pr.h index 2f9a8829552b..46a46d328fbf 100644 --- a/arch/powerpc/kvm/trace_pr.h +++ b/arch/powerpc/kvm/trace_pr.h @@ -8,8 +8,6 @@ #undef TRACE_SYSTEM #define TRACE_SYSTEM kvm_pr -#define TRACE_INCLUDE_PATH . -#define TRACE_INCLUDE_FILE trace_pr TRACE_EVENT(kvm_book3s_reenter, TP_PROTO(int r, struct kvm_vcpu *vcpu), @@ -257,4 +255,11 @@ TRACE_EVENT(kvm_exit, #endif /* _TRACE_KVM_H */ /* This part must be outside protection */ + +#undef TRACE_INCLUDE_PATH +#undef TRACE_INCLUDE_FILE + +#define TRACE_INCLUDE_PATH . +#define TRACE_INCLUDE_FILE trace_pr + #include -- GitLab
