From: Jens Freimann <[email protected]> We need BITS_TO_LONGS, not sizeof(long) to calculate the correct size.
idle_mask is a bitmask, each bit representing the state of a cpu. The desired outcome is an array of unsigned long fields that can fit KVM_MAX_VCPUS bits. We should not use sizeof(long) which returnes the size in bytes, but BITS_TO_LONGS Signed-off-by: Jens Freimann <[email protected]> Reviewed-by: Cornelia Huck <[email protected]> Signed-off-by: Christian Borntraeger <[email protected]> --- arch/s390/include/asm/kvm_host.h | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/arch/s390/include/asm/kvm_host.h b/arch/s390/include/asm/kvm_host.h index 734d302..c36cd35 100644 --- a/arch/s390/include/asm/kvm_host.h +++ b/arch/s390/include/asm/kvm_host.h @@ -213,8 +213,7 @@ struct kvm_s390_float_interrupt { struct list_head list; atomic_t active; int next_rr_cpu; - unsigned long idle_mask[(KVM_MAX_VCPUS + sizeof(long) - 1) - / sizeof(long)]; + unsigned long idle_mask[BITS_TO_LONGS(KVM_MAX_VCPUS)]; unsigned int irq_count; }; -- 1.8.4.2 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
