Modified Files: src/sys/uvm [matt-nb5-mips64]: uvm_param.h Log Message: Redefine ptoa() to be the inverse of atop. If you were using a 32-bit vaddr_t with 64-bit paddr_t and using managed addresses > 4GB, uvm_page_init would silently discard the upper 32-bits of the physical address possibly double mapping pages.
