In do_page_fault(), we handle some kernel faults early, and simply die() with a message. For faults handled later, we dump the faulting address, decode the ESR, walk the page tables, and perform a number of steps to ensure that this data is reported. Let's unify the handling of fatal kernel faults with a new die_kernel_fault() helper, handling all of these details. This is largely the same as the existing logic in __do_kernel_fault(), except that addresses are consistently padded to 16 hex characters, as would be expected for a 64-bit address. The messages currently logged in do_page_fault are adjusted to fit into the die_kernel_fault() message template.
