ok, these latest ring-buffer updates cause more serious trouble, i just
got this boot crash on a testbox:

full serial log and config attached. I'm excluding these latest commits
from tip/master for now:
339ce9a: ring-buffer: fix build error
b6eeea4: ftrace: preempt disable over interrupt disable
52abc82: ring_buffer: allocate buffer page pointer
da78331: ftrace: type cast filter+verifier
i'm quite sure 52abc82 causes this problem.
Another 64-bit testbox crashed too meanwhile.
