John Baldwin 67b0b90785 i386: Always bounce DMA requests above 4G for !PAE kernels ... i386 kernels without 'options PAE' will still use PAE page tables if the CPU supports PAE both to support larger amounts of RAM and for PG_NX permissions. However, to avoid changing the API, bus_addr_t and related constants (e.g. BUS_SPACE_MAXADDR) are still limited to 32 bits. To cope with this, the x86 bus_dma code included an extra check to bounce requests for addresses above BUS_SPACE_MAXADDR. This check was elided (probably because it looks always-true on its face and had no comment explaining its purpose) in recent refactoring. To fix, restore a custom address-validation function for i386 kernels without options PAE that includes this check.
