+ Fix the root cause of the hack "disable optimizations for uvm_bio.c
+ on 32 bit kernels".
+
+ gcc converts a division in the calculation of UBC_UMAP_ADDR macro
+ to multiplication (smul or combination of add/sll), and the
+ register of its result contains a garbage in upper 32 bits (the
+ upper 32 bits of smul/add/sll's result isn't zero cleared).
+
+ Then it passes to pseg_get{,_real} through pmap_extract without the
+ zero clear of upper 32 bits in the optimization case. So the
+ result of pseg_get and pmap_extact sometimes gets screwed up.
