KVM already treats a NULL hart-mask pointer in SBI v0.1 calls as all harts, matching OpenSBI's legacy handling. The current handler builds that target set as (1UL << online_vcpus) - 1 before iterating the mask. That expression shifts by the type width once the VM has BITS_PER_LONG online vCPUs, and a single word cannot represent larger VMs. A count-based mask also selects the wrong IDs when vCPU IDs are sparse. Handle SEND_IPI with a NULL hart-mask by iterating all online vCPUs directly. For remote fence calls, use the existing hbase == -1UL convention so the common fence request helper targets the whole VM without consulting hmask. Non-NULL guest hart masks keep the existing v0.1 behavior.
