This indicates some kind of bug in kernprof. An "UNKNOWN_KERNEL" is
outside the range of known kernel addresses, and is not in the range of
module addresses or firmware addresses. My guess is that this
"UNKNOWN_ADDRESS" *is* one of those things, but drivers/char/profile.c
isn't properly computing the address ranges of those "non-kernel"
entities.
Are you seeing a large value for UNKNOWN_ADDRESS? If not, then ignore
it. I'll try to figure this out, as time permits.
