When constructing the set of dumpable pages, use the bitset provided by the state argument, rather than assuming vm_page_dump invariably. For normal kernel minidumps this will be a pointer to vm_page_dump, but when dumping the live system it will not. To do this, the functions in vm_dumpset.h are extended to accept the desired bitset as an argument. Note that this provided bitset is assumed to be derived from vm_page_dump, and therefore has the same size. Reviewed by: kib, markj, jhb MFC after: 2 weeks Sponsored by: Juniper Networks, Inc.
