This patch add a two byte eir_len parameter mgmt_ev_device_found. Since
it's unlikely that the data will in the short term be much bigger than
conventional EIR lengths just use a small stack based buffer for now to
avoid dynamic memory allocation & freeing.

This patch makes sure that devices with stronger signal (RSSI closer to
0) are sorted first in the resolve list and will therefore get their
names resolved first during device discovery. Since it's more likely
that the device the user is trying to discover has a strong signal due
to its proximity this ensures that the user gets the "device found"
event for it more quickly.

The hci_dev->dev device structure has an internal refcount. This
refcount is used to protect the whole hci_dev object. However, we
currently do not use it. Therefore, if someone calls hci_free_dev() we
currently immediately destroy the hci_dev object because we never took
the device refcount.
This even happens if the hci_dev->refcnt is not 0. In fact, the
hci_dev->refcnt is totally useless in its current state. Therefore, we
simply remove hci_dev->refcnt and instead use hci_dev->dev refcnt.
This fixes all the symptoms and also correctly integrates the device

Added is a new static inline function that lets *any* tracepoint be used
inside a rcu_idle_exit() section. And this also solves the problem where
the same tracepoint may be used inside a rcu_idle_exit() section as well
as outside of one.
I added a new tracepoint function with a "_rcuidle" extension. All
tracepoints can be used with either the normal "trace_foobar()"
function, or the "trace_foobar_rcuidle()" function when inside a
rcu_idle_exit() section.
All tracepoints defined by TRACE_EVENT() or any of the derivatives
will have a "_rcuidle()" function also defined. When a tracepoint is
used within an rcu_idle_exit() section, the "_rcuidle()" version must
be used. This denotes that the tracepoint is within rcu_idle_exit()
and it allows the rcu read locks within the tracepoint to still
be valid, as this version takes us out of rcu_idle_exit().
Another nice aspect about this patch is that "static inline"s are not
compiled into text when not used. So only the tracepoints that actually
use the _rcuidle() version will have them defined in the actual text
that is booted.

Currently, it is not easily possible to get TOS/DSCP value of packets from
an incoming TCP stream. The mechanism is there, IP_PKTOPTIONS getsockopt
with IP_RECVTOS set, the same way as incoming TTL can be queried. This is
not actually implemented for TOS, though.
This patch adds this functionality, both for IPv4 (IP_PKTOPTIONS) and IPv6
(IPV6_2292PKTOPTIONS). For IPv4, like in the IP_RECVTTL case, the value of
the TOS field is stored from the other party's ACK.
This is needed for proxies which require DSCP transparency. One such example
is at http://zph.bratcheda.org/.

Somehow we ended up with duplicate hub feature #defines in ch11.h.
Tatyana Brokhman first created the USB 3.0 hub feature macros in 2.6.38
with commit 0eadcc0920 "usb: USB3.0 ch11
definitions". In 2.6.39, I modified a patch from John Youn that added
similar macros in a different place in the same file, and committed
dbe79bbe9d "USB 3.0 Hub Changes".
Some of the #defines used different names for the same values. Others
used exactly the same names with the same values, like these gems:
#define USB_PORT_FEAT_BH_PORT_RESET 28
...
#define USB_PORT_FEAT_BH_PORT_RESET 28
According to my very geeky husband (who looked it up in the C99 spec),
it is allowed to have object-like macros with duplicate names as long as
the replacement list is exactly the same. However, he recalled that
some compilers will give warnings when they find duplicate macros. It's
probably best to remove the duplicates in the stable tree, so that the
code compiles for everyone.
The macros are now fixed to move the feature requests that are specific
to USB 3.0 hubs into a new section (out of the USB 2.0 hub feature
section), and use the most common macro name.
This patch should be backported to 2.6.39.

Traditionally, any System-on-Chip based platform creates a flat list

In order to give these some better structure, this introduces a new
bus type for soc_devices that are registered with the new
soc_device_register() function. All devices that are on the same
chip should then be registered as child devices of the soc device.
The soc bus also exports a few standardised device attributes which
allow user space to query the specific type of soc.
