elf.h is supposedly exported in 2.6.22, although I guess someone took the
comment seriously:
# These probably shouldn't be exported
unifdef-y += shmparam.h
unifdef-y += elf.h
unifdef-y += page.h
So, I have no idea how userspace is supposed to figure out how big a
buffer to pass to PTRACE_GETFPREGS and PTRACE_GETFPXREGS. I think the
headers are broken here.

This is just broken, then. The headers should at least have no
dangling includes.

Hummm, I guess the header tidying people need to fix a bunch of
things. I'll make whatever changes needed in UML to not use illicit
headers, but I do need complete interface definitions, as with the FP
stuff.
