This patch propagates users' requested flow-control into the link layer,
which will later be used to advertise this flow-control for auto-negotiation
(until now these values were ignored).

Prevent updating the xmac PFC configuration when using a link speed
slower than 10G -the umac block is responsible for 1G or slower connections,
therefore it is possible the xmac block is reset when connection is slower.

FW needs the driver statistics for management. Current logic is broken
in that the function that gathers the port statistics does not copy
its own statistics to a place where the FW can use it.
This patch causes every function that can pass statistics to the FW to
do so.

During traffic when DCB is enabled, it is possible for multiple instances
of statistics queries to be sent to the chip - this may cause the FW to assert.
This patch prevents the sending of an additional instance of statistics query
while the previous query hasn't completed.

Only increase the higher 32bits if we really detect a wrap around.
v2: instead of increasing the higher 32bits just use the higher
32bits from the last emitted fence.
v3: also use last emitted fence value as upper limit.
The intention of this patch is to make fences as robust as
they where before introducing 64bit fences. This is
necessary because on older systems it looks like the fence
value gets corrupted on initialization.

For DP we can use the same PPLL for all active DP
encoders. Take advantage of that to prevent cases
where we may end up sharing a PPLL between DP and
non-DP which won't work. Also clean up the code
a bit.
v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
- document functions
- break in main encoder search loop after matching.
no need to keep checking additional encoders.

This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.
commit 230718bd net: qmi_wwan: bind to both control and data interface
changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function. The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.
The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended. Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

gred_dequeue() and gred_drop() do not seem to get called when the
queue is empty, meaning that we never start idling while in WRED
mode. And since qidlestart is not stored by gred_store_wred_set(),
we would never stop idling while in WRED mode if we ever started.
This messes up the average queue size calculation that influences
packet marking/dropping behavior.
Now, we start WRED mode idling as we are removing the last packet
from the queue. Also we now actually stop WRED mode idling when we
are enqueuing a packet.

q->vars.qavg is a Wlog scaled value, but q->backlog is not. In order
to pass q->vars.qavg as the backlog value, we need to un-scale it.
Additionally, the qave value returned via netlink should not be Wlog
scaled, so we need to un-scale the result of red_calc_qavg().
This caused artificially high values for "Average Queue" to be shown
by 'tc -s -d qdisc', but did not affect the actual operation of GRED.

It is a bad idea to hold a spinlock and call flush_work_sync.
Move the workqueue cleanup outside the spinlock and use cancel_work_sync,

The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.
This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.

in nfnetlink_log, from Eric Dumazet.
* Fix broken syslog log-level for xt_LOG and ebt_log since printk format was
converted from <.> to a 2 bytes pattern using ASCII SOH, from Joe Perches.
* Two security fixes for the TCP connection tracking targeting off-path attacks,
from Jozsef Kadlecsik. The problem was discovered by Jan Wrobel and it is

With 3.4 kernel the static iomappings can be shared with the ioremap
mappings. If ioremap is called with an address for which a static
mapping already exists, then that mapping should be used instead
of creating a new one.
However, the MT_DEVICE_NONSHARED flag prevents this. Hence, get rid
of this flag. Some targets (7X00) that require the static iomappings
to be NONSHARED use the MSM_DEVICE_TYPE and MSM_CHIP_DEVICE_TYPE macros.

A previous patch[1] added code to initialize an FPGA register on the
8660 "SURF" development platform. Since this development platform is
not widely available, and there is now a more available device "the
Dragonboard" based on the same core SOC, this change was dropped.
However, the DT code kept a lingering call to this FPGA init function.

This adds a 'struct smp_operations' to abstract the CPU initialization
and hot plugging functions on SMP systems, which otherwise conflict
in a multiplatform kernel. This also helps shmobile and potentially
others that have more than one method to do these.
To allow the kernel to continue building, the platform hooks are
defined as weak symbols which are overrided by the platform code.
Once all platforms are converted, the "weak" attribute will be
removed and the function made static.
Unlike the original version from Marc, this new version from Arnd
does not use a generalized abstraction for per-soc data structures
but only tries to solve the problem for the SMP operations. This
way, we can collapse the previous four data structures into a
single struct, which is less systematic but also easier to follow
as a causal reader.
