Konstantin Belousov c325e866f4 Different consumers of the struct vm_page abuse pageq member to keep ... additional information, when the page is guaranteed to not belong to a paging queue. Usually, this results in a lot of type casts which make reasoning about the code correctness harder. Sometimes m->object is used instead of pageq, which could cause real and confusing bugs if non-NULL m->object is leaked. See r141955 and r253140 for examples. Change the pageq member into a union containing explicitly-typed members. Use them instead of type-punning or abusing m->object in x86 pmaps, uma and vm_page_alloc_contig().
