I do __aligned(64) when I declare variable of that type:
static DEFINE_PER_CPU(struct kvm_vcpu_pv_apf_data, apf_reason) __aligned(64);
64 byte boundary: You mean cacheline aligned? We have a special define for
that.
DEFINE_PER_CPU_SHARED_ALIGNED
It's an ABI, so we can't use something that might change when Intel
releases a cpu with 75.2 byte cache lines.
