Using a linked-list for LPIs is less than ideal as it of course requires iterative searches to find a particular entry. An xarray is a better data structure for this use case, as it provides faster searches and can still handle a potentially sparse range of INTID allocations. Start by storing LPIs in an xarray, punting usage of the xarray to a subsequent change. The observant among you will notice that we added yet another lock to the chain of locking order rules; document the ordering of the xa_lock. Don't worry, we'll get rid of the lpi_list_lock one day...
