xeon-phi: update for the xeon phi patches

In ibp cm server change list modification patterns to be atomic. Before adding and removing
from a list would go something like:

1)      Find item in list while holding reader lock
2)      …
3)      Search again for found item while holding writer lock, remove it

Multiple threads could end up holding pointers to items in the list and by the time they get to
deleting it, it may or may not exist in list.

Also: the ibp cm event handler for cm events should always return 0, if it returns non-zero ib_cm
will attempt to remove the cm_id, which is not correct (and causes ib_cm worker thread to dump
stack and hang).

Finally: trivial change an ibscif printk log level to KERN_INFO vs ALERT.

IB/security: Restrict use of the write() interface

The drivers/infiniband stack uses write() as a replacement for
bi-directional ioctl().  This is not safe. There are ways to
trigger write calls that result in the return structure that
is normally written to user space being shunted off to user
specified kernel memory instead.

For the immediate repair, detect and deny suspicious accesses to
the write API.

For long term, update the user space libraries and the kernel API
to something that doesn't present the same security vulnerabilities
(likely a structured ioctl() interface).

The impacted uAPI interfaces are generally only available if
hardware from drivers/infiniband is installed in the system.

xeon-phi: ibscif bug 2575: Allow xeon-phi support for Knights Landing

New patch file for the compat-rdma tech-preview/xeon-phi directory

The Knights Landing (KNL) version of Intel mpss will use the scif driver that
was upstreamed to kernel.org.  Although the data structure layout is the same
as the Knights Corner (KNC) version, some functions have changed.  The
scif_get_nodeIDs call is renamed to scif_get_node_ids and the scif_pci_info is
removed.  These changes impact the ibscif and ib_qib drivers for KNL.  The
attached patch will allow OFED-3.18-1 --with-xeon-phi to work with both
versions of mpss.  This new patch file should be added to the compat-rdma
source rpm in the tech-preview/xeon-phi directory.
