I'm more in favour of an on/off hexdump feature (maybe even permanently
on) and with a limit to the number of bytes it displays. For larger
blocks, the hexdump=OBJECT_POINTER is easily achievable in user space
via /dev/kmem.
My proposal is for an always on hexdump but with no more than 2-3 lines
of hex values. As Pekka said, I should get it into linux-next before the
next merging window.
