Other variables can be made static, thereby eliminating the need for a declaration. Doing so also resolves violations of MISRA C:2012 Rule 8.4. Fix typo s/mcinfo_dumpped/mcinfo_dumped/ while making the variable static. Signed-off-by: Nicola Vetrini Reviewed-by: Stefano Stabellini Acked-by: Jan Beulich --- Jan's ack is for the x86 part, but no other concerns have been raised for the arm files. Changes in v2: - make xenpf_lock static on ARM Changes in v3: - moved back code from symbols.h to symbols.c - dropped two declarations, now deviated Changes in v4: - revise commit message --- xen/arch/arm/include/asm/setup.h | 3 +++ xen/arch/arm/include/asm/smp.h | 3 +++ xen/arch/arm/platform_hypercall.c | 2 +- xen/arch/x86/cpu/mcheck/mce.c | 7 ++++--- xen/arch/x86/irq.c | 2 +- xen/include/xen/symbols.h | 1 + 6 files changed, 13 insertions(+), 5 deletions(-) diff --git a/xen/arch/arm/include/asm/setup.h b/xen/arch/arm/include/asm/setup.h index 98af6f55f5a0..2a2d6114f2eb 100644 --- a/xen/arch/arm/include/asm/setup.h +++ b/xen/arch/arm/include/asm/setup.h @@ -184,9 +184,12 @@ int map_range_to_domain(const struct dt_device_node *dev, extern lpae_t boot_pgtable[XEN_PT_LPAE_ENTRIES]; #ifdef CONFIG_ARM_64 +extern lpae_t boot_first[XEN_PT_LPAE_ENTRIES]; extern lpae_t boot_first_id[XEN_PT_LPAE_ENTRIES]; #endif +extern lpae_t boot_second[XEN_PT_LPAE_ENTRIES]; extern lpae_t boot_second_id[XEN_PT_LPAE_ENTRIES]; +extern lpae_t boot_third[XEN_PT_LPAE_ENTRIES * XEN_NR_ENTRIES(2)]; extern lpae_t boot_third_id[XEN_PT_LPAE_ENTRIES]; /* Find where Xen will be residing at runtime and return a PT entry */ diff --git a/xen/arch/arm/include/asm/smp.h b/xen/arch/arm/include/asm/smp.h index 4fabdf5310d8..28bf24a01d95 100644 --- a/xen/arch/arm/include/asm/smp.h +++ b/xen/arch/arm/include/asm/smp.h @@ -6,6 +6,9 @@ #include #endif +extern struct init_info init_data; +extern unsigned long smp_up_cpu; + DECLARE_PER_CPU(cpumask_var_t, cpu_sibling_mask); DECLARE_PER_CPU(cpumask_var_t, cpu_core_mask); diff --git a/xen/arch/arm/platform_hypercall.c b/xen/arch/arm/platform_hypercall.c index 743687a30390..fde4bc3e5809 100644 --- a/xen/arch/arm/platform_hypercall.c +++ b/xen/arch/arm/platform_hypercall.c @@ -17,7 +17,7 @@ #include #include -DEFINE_SPINLOCK(xenpf_lock); +static DEFINE_SPINLOCK(xenpf_lock); long do_platform_op(XEN_GUEST_HANDLE_PARAM(xen_platform_op_t) u_xenpf_op) { diff --git a/xen/arch/x86/cpu/mcheck/mce.c b/xen/arch/x86/cpu/mcheck/mce.c index 6141b7eb9cf1..779a458cd88f 100644 --- a/xen/arch/x86/cpu/mcheck/mce.c +++ b/xen/arch/x86/cpu/mcheck/mce.c @@ -1682,13 +1682,14 @@ long do_mca(XEN_GUEST_HANDLE_PARAM(xen_mc_t) u_xen_mc) return ret; } -int mcinfo_dumpped; +static int mcinfo_dumped; + static int cf_check x86_mcinfo_dump_panic(mctelem_cookie_t mctc) { struct mc_info *mcip = mctelem_dataptr(mctc); x86_mcinfo_dump(mcip); - mcinfo_dumpped++; + mcinfo_dumped++; return 0; } @@ -1702,7 +1703,7 @@ static void mc_panic_dump(void) for_each_online_cpu(cpu) mctelem_process_deferred(cpu, x86_mcinfo_dump_panic, mctelem_has_deferred_lmce(cpu)); - dprintk(XENLOG_ERR, "End dump mc_info, %x mcinfo dumped\n", mcinfo_dumpped); + dprintk(XENLOG_ERR, "End dump mc_info, %x mcinfo dumped\n", mcinfo_dumped); } void mc_panic(const char *s) diff --git a/xen/arch/x86/irq.c b/xen/arch/x86/irq.c index f42ad539dcd5..ecd67f7f8416 100644 --- a/xen/arch/x86/irq.c +++ b/xen/arch/x86/irq.c @@ -43,7 +43,7 @@ int __read_mostly opt_irq_vector_map = OPT_IRQ_VECTOR_MAP_DEFAULT; static unsigned char __read_mostly irq_max_guests; integer_param("irq-max-guests", irq_max_guests); -vmask_t global_used_vector_map; +static vmask_t global_used_vector_map; struct irq_desc __read_mostly *irq_desc = NULL; diff --git a/xen/include/xen/symbols.h b/xen/include/xen/symbols.h index 20bbb28ef226..1b2863663aa0 100644 --- a/xen/include/xen/symbols.h +++ b/xen/include/xen/symbols.h @@ -33,4 +33,5 @@ struct symbol_offset { uint32_t stream; /* .. in the compressed stream.*/ uint32_t addr; /* .. and in the fixed size address array. */ }; + #endif /*_XEN_SYMBOLS_H*/
