The output seen from show_regs/show_registers is probably what most people
(that is, Linux kernel hackers) will expect.  As someone who deals with
such output all the time myself, all I care about is that all the registers
are there and that it's always clear what's in hex and what's in decimal.
(Your example is fine where it's clear that everything is in hex without 0x.)

Using print_symbol for the PC is nice for humans, though probably redundant
and a waste of CPU if the dump will be digested by a program.

People might find it less surprising if you use the syntax %2$d to mean %d
format of key number 2.  In userland printf, that's what means %d format of
the 2nd positional argument.
