vms and vcpus have statistics associated with them which can be viewed within the debugfs. Currently it is assumed within the vcpu_stat_get() and vm_stat_get() functions that all of these statistics are represented as u32s, however the next patch adds some u64 statistics. Thus modify these two functions, vcpu_stat_get() and vm_stat_get(), such that they expect u64 statistics and update vm and vcpu statistics to u64s accordingly. --- Change Log: V1 -> V2: - Nothing V2 -> V3: - Instead of implementing separate u32 and u64 functions keep the generic functions and modify them to expect u64s. Thus update all vm and vcpu statistics to u64s accordingly.
