Hmm. Has the default search path for the vmlinux image changed?

Doing profiling with this, I get

    openat(AT_FDCWD, "vmlinux", O_RDONLY)   = 5

which is very very wrong for my kernel build - it basically picks up
the vmlinux image from the build directory, which has absolutely
*nothign* to do with the image that is being run at the moment.

So now I need to point "perf report" at the actual image, which I
didn't need to do before.
