Peter Maydell 0d6cada970 target/sparc: Correctly handle bus errors in page table walks Currently we use the ldl_phys() function to read page table entries. With the unassigned_access hook in place, if these hit an unassigned area of memory then the hook will cause us to wrongly generate an exception with a fault address matching the address of the page table entry. Change to using address_space_ldl() so we can detect and correctly handle bus errors and give them their correct behaviour of causing a translation error with a suitable fault status register. Note that this won't actually take effect until we switch the over to using the do_translation_failed hook.
