| H A D | vm_phys.h | diff 236924 Mon Jun 11 19:35:11 MDT 2012 kib MFC r235372: Add a facility to register a range of physical addresses to be used for allocation of fictitious pages, for which PHYS_TO_VM_PAGE() returns proper fictitious vm_page_t. The range should be de-registered after consumer stopped using it. De-inline the PHYS_TO_VM_PAGE() since it now carries code to iterate over registered ranges. MFC r235776 (by andrew): In PHYS_TO_VM_PAGE() when VM_PHYSSEG_DENSE is set the check if we are past the end of vm_page_array was incorrect causing it to return NULL. This value is then used in vm_phys_add_page causing a data abort. |
