That's fine. The problem is that the peek operation returns less
data than requested even when sufficient data is available on the

This patch removes the preempt_disable/enable pair around kprobe_running
which was originally added to avoid the assertion from smp_processor_id
which would be hit an asertion if preemption was enabled.
Kprobes can not be running if we are preemptible, so test explicitly
for preemption and bail ou

Use a central kprobe_handle_fault() inline in kprobes.h to remove
all of the arch-dependant, practically identical implementations in
avr32, ia64, powerpc, s390, sparc64, and x86.
avr32 was the only arch without the preempt_disable/enable pair
in its notify_page_fault implementation.

Nothing that seems *crucial* going forward for Linux. The fate of
"legacy machines" is really important to get right.
