kernel: INTR_GET_KERNEL_TABLE subtreeMap = intrInitSubtreeMap_TU102 values
Driver's intrCacheIntrFields requires subtree(ACCESS_CNTR=72)=1 within
subtreeMap[UVM_OWNED] and UVM_SHARED to be a single subtree. Zeroed map
failed RmInitNvDevice state load ('unexpected subtree').
Map matches intrInitSubtreeMap_TU102 (what physical-path guests get from
real GSP-RM): ESCHED{3,3} ESCHED_NOTIF{0,0} UVM_OWNED{1,1} UVM_SHARED{2,2},
DEFAULT/RUNLIST/RUNLIST_NOTIF=INVALID(0xFF). Struct retyped to 7x2B;
out_params_size spans full struct (driver reads subtreeMap at offset 2052).
Verified: probe passes state load, /dev/nvidia0 persists.
