While computing slice mask for the free area we need make sure we only search
in the addr limit applicable for this mmap. We update the slb_addr_limit
after we request for a mmap above 128TB. But the following mmap request
with hint addr below 128TB should still limit its search to below 128TB. ie.
we should not use slb_addr_limit to compute slice mask in this case. Instead,
we should derive high addr limit based on the mmap hint addr value.
