Add all the required code to program the GENET hardware to enter
Wake-on-LAN mode and wake using MagicPackets with or without SecureOn
password.
This code is hooked to the build system, but is not yet referenced from
ethtool or the main bcmgenet driver.

- A fix for a regression where we woud crash on queue exit if the

"Late libata fixes.
The most important one is from Kevin Hao which makes sure that libata
only allocates tags inside the max tag number the controller supports.
libata always had this problem but the recent tag allocation change
and addition of support for sata_fsl which only supports queue depth
of 16 exposed the issue.
Hans de Goede agreed to become the maintainer of libahci_platform
which is under higher than usual development pressure from all the new
controllers popping up from the ARM world"

libata: EH should handle AMNF error condition as a media error
libata: support the ata host which implements a queue depth less than 32

nested virtualization and there were other changes in this area in 3.16,

The "uptime" trace clock added in:
commit 8aacf017b0
tracing: Add "uptime" trace clock that uses jiffies
has wraparound problems when the system has been up more
than 1 hour 11 minutes and 34 seconds. It converts jiffies
to nanoseconds using:
(u64)jiffies_to_usecs(jiffy) * 1000ULL
but since jiffies_to_usecs() only returns a 32-bit value, it
truncates at 2^32 microseconds. An additional problem on 32-bit
systems is that the argument is "unsigned long", so fixing the
return value only helps until 2^32 jiffies (49.7 days on a HZ=1000
system).
Avoid these problems by using jiffies_64 as our basis, and
not converting to nanoseconds (we do convert to clock_t because
user facing API must not be dependent on internal kernel
HZ values).

When a VLAN interface (on top of batX) is removed and
re-added within a short timeframe TT does not have enough
time to properly cleanup. This creates an internal TT state
mismatch as the newly created softif_vlan will be
initialized from scratch with a TT client count of zero
(even if TT entries for this VLAN still exist). The
resulting TT messages are bogus due to the counter / tt
client listing mismatch, thus creating inconsistencies on
every node in the network
To fix this issue destroy_vlan() has to not free the VLAN
object immediately but it has to be kept alive until all the
TT entries for this VLAN have been removed. destroy_vlan()
still removes the sysfs folder so that the user has the
feeling that everything went fine.
If the same VLAN is re-added before the old object is free'd,
then the latter is resurrected and re-used.
Implement such behaviour by increasing the reference counter
of a softif_vlan object every time a new local TT entry for
such VLAN is created and remove the object from the list
only when all the TT entries have been destroyed.

Since bridge loop avoidance only supports untagged or simple 802.1q
tagged VLAN claim frames, claim frames with stacked VLAN headers (QinQ)
should be detected and dropped. Transporting the over the mesh may cause
problems on the receivers, or create bogus entries in the local tt
tables.
