NAMEpmap_unwire - unwire a range of virtual pages
SYNOPSISIn sys/param.h In vm/vm.h In vm/pmap.h Ft void Fo pmap_unwire Fa pmap_t pmap vm_offset_t start vm_offset_t end Fc
The function Fn pmap_unwire removes the wired attribute from each of the virtual-to-physical page mappings within the virtual address range from Fa start to Fa end of the physical map Fa pmap . Every valid mapping within that range is required to have the wired attribute set. Invalid mappings are ignored, since they cannot have the wired attribute set.
