Alan Cox 43ded0a321 In pmap_advise(), when we encounter a superpage mapping, we first demote the ... mapping and then destroy one of the 4 KB page mappings so that there is a potential trigger for repromotion. Currently, we destroy the first 4 KB page mapping that falls within the (current) superpage mapping or the virtual address range [sva, eva). However, I have found empirically that destroying the last 4 KB mapping produces slightly better results, specifically, more promotions and fewer failed promotion attempts. Accordingly, this revision changes pmap_advise() to destroy the last 4 KB page mapping. It also replaces some nearby uses of boolean_t with bool.
