Change number of ports to 3 for newer SoCs. Modify pdata structure
and ohci-at91 code that was dealing with ports information and check
of port indexes.
Several coding style errors have been addresses as the patch was touching
affected lines of code and was producing errors while run through
checkpatch.pl.

The DT information are filled in a pdata structure and then passed on
to the usual check code of the probe function. Thus we do not need to
redo the gpio checking and irq configuration in the DT-related code.
On the other hand, we setup GPIO direction in driver for vbus and
overcurrent. It will be useful when moving to pinctrl subsystem.

addruart cannot read from the physical address of the chipid
register, that will fail as soon as the mmu is turned on.
Fixing it to read from the physical or virtual address depending
on the mmu state also does not work, because there is a period
between head.S and exynos_map_io where the mmu is on, the uart
is mapped and used, but the chipid mapping is not yet present.
Fix addruart to use the ARM Main ID cp15 register to determine
if the core is Cortex A15 (EXYNOS5) or not (EXYNOS4).

clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y.
Since clk_disable_unused is called as lateinitcall, there can
be more than a few workqueues executing off secondary CPU(s).
The current code does the following:
a) checks if clk is unused
b) holds lock
c) disables clk
d) unlocks
Between (a) and (b) being executed on CPU0, It is possible to
have a driver executing on CPU1 which could do a get_sync->clk_get
(and increase the use_count) of the clock which was just about
to be disabled by clk_disable_unused.
We ensure instead that the entire list traversal is protected by
the lock allowing for parent child clock traversal which could be
potentially be done by runtime operations to be safe as well.

Commit 2a9f5a4d455 "OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck,
added for 36xx" consolidated dpll4 clock structures between 34xx and 36xx,
but left 34xx CLKSEL masks for most dpll4 related clocks, which causes
clock code to not behave correctly when booting on DM3730 with higher
(36xx only) divisors set:
[ 0.000000] WARNING: at arch/arm/mach-omap2/clkt_clksel.c:375 omap2_init_clksel_parent+0x104/0x114()

[ 0.000000] clock: Could not find fieldval 0 for clock dpll4_m3_ck parent dpll4_ck
Fix this by switching to 36xx masks, as valid divisors will be limited
by clksel_rate lists.

If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems
2.1.1.128 erratum doesn't apply and there is no data corruption,
probably because of different signal timing. The workaround for this
erratum disables multiblock reads, which causes dramatic loss of
performance (over 75% slower), so avoid it when transceiver is present.

Fix up code so that changes in DCB settings
are detected only when ixgbe_dcbnl_set_all is called.
Previously, a series of 'change' commands followed by
a call to ixgbe_dcbnl_set_all() would always be handled
as a HW change - even if the net change was zero.
This patch checks for this case of no actual change and
skips going through the HW set process.
Without this fix, the link could reset and result in
a link flap.
The core change in this patch is to check for changes
in the ixgbe_copy_dcb_cfg() routine - and return
a bitmask of detected changes. The other
places where changes were detected previously can be removed.

Now the helper function from filter.c for negative offsets is exported,
it can be used it in the jit to handle negative offsets.
First modify the asm load helper functions to handle:
- know positive offsets
- know negative offsets
- any offset
then the compiler can be modified to explicitly use these helper
when appropriate.
This fixes the case of a negative X register and allows to lift
the restriction that bpf programs with negative offsets can't

vmsplice()/splice(pipe, socket) call do_tcp_sendpages() one page at a
time, adding at most 4096 bytes to an skb. (assuming PAGE_SIZE=4096)
The call to tcp_push() at the end of do_tcp_sendpages() forces an
immediate xmit when pipe is not already filled, and tso_fragment() try
to split these skb to MSS multiples.
4096 bytes are usually split in a skb with 2 MSS, and a remaining
sub-mss skb (assuming MTU=1500)
This makes slow start suboptimal because many small frames are sent to
qdisc/driver layers instead of big ones (constrained by cwnd and packets
in flight of course)
In fact, applications using sendmsg() (adding an additional memory copy)
instead of vmsplice()/splice()/sendfile() are a bit faster because of
this anomaly, especially if serving small files in environments with
large initial [c]wnd.
Call tcp_push() only if MSG_MORE is not set in the flags parameter.
This bit is automatically provided by splice() internals but for the
last page, or on all pages if user specified SPLICE_F_MORE splice()
flag.
In some workloads, this can reduce number of sent logical packets by an
order of magnitude, making zero-copy TCP actually faster than
one-copy :)

For every transmitted packet, ppp_start_xmit() will stop the netdev
queue and then, if appropriate, restart it. This causes the TX softirq
to run, entirely gratuitously.
This is "only" a waste of CPU time in the normal case, but it's actively
harmful when the PPP device is a TEQL slave — the wakeup will cause the
offending device to receive the next TX packet from the TEQL queue, when
it *should* have gone to the next slave in the list. We end up seeing
large bursts of packets on just *one* slave device, rather than using
the full available bandwidth over all slaves.
This patch fixes the problem by *not* unconditionally stopping the queue
in ppp_start_xmit(). It adds a return value from ppp_xmit_process()
which indicates whether the queue should be stopped or not.
It *doesn't* remove the call to netif_wake_queue() from
ppp_xmit_process(), because other code paths (especially from
ppp_output_wakeup()) need it there and it's messy to push it out to the
other callers to do it based on the return value. So we leave it in
place — it's a no-op in the case where the queue wasn't stopped, so it's
harmless in the TX path.

Commit f04565ddf52 (dev: use name hash for dev_seq_ops) added a second
regression, as some devices are missing from /proc/net/dev if many
devices are defined.
When seq_file buffer is filled, the last ->next/show() method is
canceled (pos value is reverted to value prior ->next() call)
Problem is after above commit, we dont restart the lookup at right
position in ->start() method.
Fix this by removing the internal 'pos' pointer added in commit, since
we need to use the 'loff_t *pos' provided by seq_file layer.
This also reverts commit 5cac98dd0 (net: Fix corruption
