From f5c54f77b07b278cfde4a654e111c39996ac8b5b Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 4 Feb 2022 09:30:13 +0100 Subject: cpumask: Add a x86-specific cpumask_clear_cpu() helper Add a x86-specific cpumask_clear_cpu() helper which will be used in places where the explicit KASAN-instrumentation in the *_bit() helpers is unwanted. Also, always inline two more cpumask generic helpers. allyesconfig: text data bss dec hex filename 190553143 159425889 32076404 382055436 16c5b40c vmlinux.before 190551812 159424945 32076404 382053161 16c5ab29 vmlinux.after Signed-off-by: Borislav Petkov Acked-by: Marco Elver Link: https://lore.kernel.org/r/20220204083015.17317-2-bp@alien8.de --- include/linux/cpumask.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include/linux/cpumask.h') diff --git a/include/linux/cpumask.h b/include/linux/cpumask.h index 6b06c698cd2a..fe29ac7cc469 100644 --- a/include/linux/cpumask.h +++ b/include/linux/cpumask.h @@ -102,7 +102,7 @@ extern atomic_t __num_online_cpus; extern cpumask_t cpus_booted_once_mask; -static inline void cpu_max_bits_warn(unsigned int cpu, unsigned int bits) +static __always_inline void cpu_max_bits_warn(unsigned int cpu, unsigned int bits) { #ifdef CONFIG_DEBUG_PER_CPU_MAPS WARN_ON_ONCE(cpu >= bits); @@ -110,7 +110,7 @@ static inline void cpu_max_bits_warn(unsigned int cpu, unsigned int bits) } /* verify cpu argument to cpumask_* operators */ -static inline unsigned int cpumask_check(unsigned int cpu) +static __always_inline unsigned int cpumask_check(unsigned int cpu) { cpu_max_bits_warn(cpu, nr_cpumask_bits); return cpu; -- cgit
