This patchset is to support DPAA FMAN PTP clock and HW timestamping.
- The patch #1 to patch #5 are to support DPAA FMAN 1588 timer in
ptp_qoriq driver.
- The patch #6 to patch #10 are to add HW timestamping support in
DPAA ethernet driver.
Yangbo Lu (10):
fsl/fman: share the event interrupt
This patch is to move ptp timer node out of fman.
Because ptp timer will be probed by ptp_qoriq driver,
it should be an independent device in case of conflict
memory mapping.

Remove arch dependent setjump/longjump functions
and unused fields in kprobe_ctlblk for jprobes
from arch/powerpc. This also reverts commits
related __is_active_jprobe() function.

Don't call the ->break_handler() from the arm kprobes code,
because it was only used by jprobes which got removed.
This also makes skip_singlestep() a static function since
only ftrace-kprobe.c is using this function.

Clear current_kprobe and enable preemption in kprobe
even if pre_handler returns !0.
This simplifies function override using kprobes.
Jprobe used to require to keep the preemption disabled and
keep current_kprobe until it returned to original function
entry. For this reason kprobe_int3_handler()

So that's easy, clear the IOMMU flag and this means "bypass the IOMMU".
