UBUNTU: SAUCE: (noup) ptrace: being capable wrt a process requires mapped uids/gids
BugLink: http://bugs.launchpad.net/bugs/1527374
ptrace_has_cap() checks whether the current process should be
treated as having a certain capability for ptrace checks
against another process. Until now, this was equivalent to
has_ns_capability(current, target_ns, CAP_SYS_PTRACE).
However, if a root-owned process wants to enter a user
namespace for some reason without knowing who owns it and
therefore can't change to the namespace owner's uid and gid
before entering, as soon as it has entered the namespace,
the namespace owner can attach to it via ptrace and thereby
gain access to its uid and gid.
While it is possible for the entering process to switch to
the uid of a claimed namespace owner before entering,
causing the attempt to enter to fail if the claimed uid is
wrong, this doesn't solve the problem of determining an
appropriate gid.
With this change, the entering process can first enter the
namespace and then safely inspect the namespace's
properties, e.g. through /proc/self/{uid_map,gid_map},
assuming that the namespace owner doesn't have access to
uid 0.

This commit wants to enable the Intel Baytrail I2C semaphore, this
driver was added into the kernel from v4.0.
The driver implements a hardware semphore to protect the I2C bus to
be shared among several users safely.
We have met a problem on a Cherry Trail platform, when we insert the
SD storage card into the SD slot, the system will hang, after enable
this driver in the kernel, the problem disappers.
This driver depends on the "CONFIG_IOSF_MBI=y", so we change this
config item from m to y.

Applications which use virtual LUN's that are backed by a physical LUN
over both adapter ports may experience an I/O failure in the event of
a link loss (e.g. cable pull).
Virtual LUNs may be accessed through one or both ports of the adapter.
This access is encoded in the translation entries that comprise the
virtual LUN and used by the AFU for load-balancing I/O and handling
failover scenarios. In a link loss scenario, even though the AFU is
able to maintain connectivity to the LUN, it is up to the application
to retry the failed I/O. When applications are unaware of the virtual
LUN's underlying topology, they are unable to make a sound decision of
when to retry an I/O and therefore are forced to make their reaction to
a failed I/O absolute. The result is either a failure to retry I/O or
increased latency for scenarios where a retry is pointless.
To remedy this scenario, provide feedback back to the application on
virtual LUN creation as to which ports the LUN may be accessed. LUN's
spanning both ports are candidates for a retry in a presence of an I/O
failure.
