From 68b5e4326e4b8ac9080835005d8254fed0fb3c56 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 9 Nov 2018 23:13:13 +0100 Subject: [PATCH] x86/mce: Fix -Wmissing-prototypes warnings MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add the proper includes and make smca_get_name() static. Fix an actual bug too which the warning triggered: arch/x86/kernel/cpu/mcheck/therm_throt.c:395:39: error: conflicting \ types for ‘smp_thermal_interrupt’ asmlinkage __visible void __irq_entry smp_thermal_interrupt(struct pt_regs *r) ^~~~~~~~~~~~~~~~~~~~~ In file included from arch/x86/kernel/cpu/mcheck/therm_throt.c:29: ./arch/x86/include/asm/traps.h:107:17: note: previous declaration of \ ‘smp_thermal_interrupt’ was here asmlinkage void smp_thermal_interrupt(void); Signed-off-by: Borislav Petkov Cc: Yi Wang Cc: Michael Matz Cc: x86@kernel.org Link: https://lkml.kernel.org/r/alpine.DEB.2.21.1811081633160.1549@nanos.tec.linutronix.de --- arch/x86/include/asm/traps.h | 6 +++--- arch/x86/kernel/cpu/mcheck/mce_amd.c | 5 +++-- arch/x86/kernel/cpu/mcheck/therm_throt.c | 3 ++- arch/x86/kernel/cpu/mcheck/threshold.c | 3 ++- 4 files changed, 10 insertions(+), 7 deletions(-) diff --git a/arch/x86/include/asm/traps.h b/arch/x86/include/asm/traps.h index 3de69330e6c5..afbc87206886 100644 --- a/arch/x86/include/asm/traps.h +++ b/arch/x86/include/asm/traps.h @@ -104,9 +104,9 @@ extern int panic_on_unrecovered_nmi; void math_emulate(struct math_emu_info *); #ifndef CONFIG_X86_32 -asmlinkage void smp_thermal_interrupt(void); -asmlinkage void smp_threshold_interrupt(void); -asmlinkage void smp_deferred_error_interrupt(void); +asmlinkage void smp_thermal_interrupt(struct pt_regs *regs); +asmlinkage void smp_threshold_interrupt(struct pt_regs *regs); +asmlinkage void smp_deferred_error_interrupt(struct pt_regs *regs); #endif extern void ist_enter(struct pt_regs *regs); diff --git a/arch/x86/kernel/cpu/mcheck/mce_amd.c b/arch/x86/kernel/cpu/mcheck/mce_amd.c index dd33c357548f..9c8e2daa48cd 100644 --- a/arch/x86/kernel/cpu/mcheck/mce_amd.c +++ b/arch/x86/kernel/cpu/mcheck/mce_amd.c @@ -23,6 +23,7 @@ #include #include +#include #include #include #include @@ -99,7 +100,7 @@ static u32 smca_bank_addrs[MAX_NR_BANKS][NR_BLOCKS] __ro_after_init = [0 ...
