Along the modesetting short cut where we skip trying to do a full
modeset and instead simply update the framebuffer base registers, we
failed to handle any errors reported.

Set the SW prio_tc values at initialization to the HW setting.
Setting the SW prio_tc default values to be the HW setting by reading the
rtrup2tc register. For any TC change we need to reset the device.
This will remove the need to reset the device at the first

At DDX commit Chris mentioned the tendency we have of finding out more
PCI IDs only when users report. So Let's add all new reserved Haswell IDs.
This patch also fix GT3 names. I'no not sending in separated patche because
names are only in few comments and not in variable names.

In order to support a more accurate check for a PTP Rx hang where the
device can no longer timestamp received packets, we need to update, per
ring, when the last Rx timestamp was. Because of how the PTP Rx hang logic
works, the current logic is valid, but properly updating the ring variable
increases the accuracy of the check.

devices regardless of if the hw semaphore has been successfully acquired via
e1000_get_hw_semaphore_82574(). With this patch, unlocking mutex now depends
on if the hw semaphore was successfully acquired before. And 82574/82583
devices are reset regardless of whether e1000_get_hw_semaphore_82574()
returns success or failure.

The assignment of IRQ for the SMC91x ethernet adapter had two
problems making it non-working:
- It was not put into the ethernet device node. Let's do this
by using the board-specific overlay, so we can make other
overlays on other Nomadik boards.
- The IRQ number was actually completely wrong, this was the
number for NHK8815, not S8815.
After this ethernet starts working on the USB S8815.

When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it
failed to boot. The issues seems to be changing by enabling or disabling
VT8550 platform. Having a quick look at dt_compat list, it seems to miss
a NULL terminator, which means of_flat_dt_match will compat check will
cross the boundary of dt_compat and fault at some point , which is what
was happening in my case.
Without this patch if we try to boot multi_v7_defconfig you might notice
that some of the platforms might fault if they fall after vt8500 in
machine-desc list. Other platforms which fall before vt8500 in mdesc list
will not fault.

The USB clocks are just clock gates, so no need to set a specific clock.
In fact trying to set a specific clock is just a NOP if the requested
clockrate is the same as those of the parent (clk_m) or will trigger a
WARN_ON() if rates don't match up.
As we are not setting a specific rate, nor activating the clocks at
init, there is no point in keeping the the usb entries in the clock init
table.

There is currently no way for an Ethernet MAC driver servicing PHY link
interrupts to notify this to the PHY state machine without defining its
own state machine. Since most drivers are not so special, introduce a
helper: phy_mac_interrupt() which can be called from a link up/down
interrupt routine to update the PHY state machine. To avoid code
duplication some refactoring has been done to expose the workqueue and
its corresponding callback internally.

When a PHY device is registered with the special IRQ value
PHY_IGNORE_INTERRUPT (-2) it will not properly be handled by the PHY
library:
- it continues to poll its register, while we do not want this
because such PHY link events or register changes are serviced by an
Ethernet MAC
- it will still try to configure PHY interrupts at the PHY level, such
interrupts do not exist at the PHY but at the MAC level
- the state machine only handles PHY_POLL, but should also handle
PHY_IGNORE_INTERRUPT similarly
This patch updates the PHY state machine and initialization paths to
account for the specific PHY_IGNORE_INTERRUPT. Based on an earlier patch
by Thomas Petazzoni, and reworked to add the missing bits. Add a helper
phy_interrupt_is_valid() which specifically tests for a PHY interrupt
not to be PHY_POLL or PHY_IGNORE_INTERRUPT and use it throughout the
code.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John W. Linville says:
====================
This pull request is intended for the 3.10 series. It contains a
variety of fixes for problems discovered during the merge window and
after 3.10-rc1.
For the mac80211 bits, Johannes says the following:
"This is what I have:
* a patch from Felix to fix RCU usage in his rate table code
* a patch from Ilan to add the wdev id to some notifications so they can
actually be used by userspace
* Sasha Levin found an issue in how hwsim handles devices
* a fix for a bug in the wiphy_register() error path that's been there forever
* three fixes for WoWLAN
* AP mode frame matching was erroneously giving frames to all virtual AP
interfaces (reported by Jouni)
* a fix for HT handling in my CSA changes, found by Sujith
* a fix for some locking simplifications gone wrong
* Ben Greear found more cfg80211/mac80211 state confusion
* and a fix for another bug found by Jouni: local state changes need to be
reported by mac80211 to cfg80211 so it disconnects properly."
And for the iwlwifi bits, he says:
"I have fixes for a firmware crash during resume, multicast RX,
aggregation and a workaround for a firmware scanning bug."
Along with those...
Albert Pool adds a USB ID to the rtl8192cu driver.
Arend van Spriel restores a driver option support flag that had been
removed from 3.9 due to a bug in that version of the driver.
Felix Fietkau fixes a trio of ath9k issues with a series of small
patches.
Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also
merged, so it isn't in the diff here).
Larry Finger gives us a fix for a build warning on big-endian systems
for rtlwifi.
Rafał Miłecki adds some core IDs to the bcma driver.
Sujith Manoharan fixes a module unloading crash in ath9k, and corrects
some calibration settings for AR9485.

TCP md5 code uses per cpu variables but protects access to them with
a shared spinlock, which is a contention point.
[ tcp_md5sig_pool_lock is locked twice per incoming packet ]
Makes things much simpler, by allocating crypto structures once, first
time a socket needs md5 keys, and not deallocating them as they are
really small.
Next step would be to allow crypto allocations being done in a NUMA
