With the multiplatform changes in arm-soc tree, it becomes
possible to enable the mvebu platform (which uses
ehci-orion) at the same time as other platforms that require
a conflicting EHCI bus glue. At the moment, this results

Load order is important in order for intel_pstate to take over as the
default scaling driver from acpi-cpufreq.
If both are built-in, acpi-cpufreq uses late_initcall() and
intel_pstate uses device_initcall() so it will be able to register as
the scaling before acpi-cpufreq for the processors supported by
intel_pstate.
If acpi-cpufreq is built as a module then intel_pstate still gets
first option to become the scaling driver.

Jeff Kirsher says:
====================
This series contains updates to igb and ixgbe. Most of the changes
are against igb, except for one patch against ixgbe.
There are 3 igb fixes from Carolyn which were reported by Dan
Carpenter which resolve issues found in the get_i2c_client(). Alex
does some cleanup of the igb driver to match similar functionality
in ixgbe on transmit. Alex also makes it so that we can enable the use
of build_skb for cases where jumbo frames are disabled. The advantage
to this is that we do not have to perform a memcpy to populate the header
and as a result we see a significant performance improvement.
Akeem provides 4 patches to initialize function pointers and do a
re-factoring of the function pointers in igb_get_variants() to assist
with driver debugging.
The ixgbe patch comes from Emil to reshuffle the switch/case structure
of the flag assignment to allow for the flags to be set for each MAC
type separately. This is needed for new hardware that does not have feature
parity with older hardware.

x86/xen: don't assume %ds is usable in xen_iret for 32-bit PVOPS.
As reported by Klaus Schmidinger:
"In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a
device (using stb0899). After this call I check 'errno' for
EOPNOTSUPP to determine whether this device supports this call. This
used to work just fine, until a few months ago I noticed that my
devices using stb0899 didn't display their signal quality in VDR's OSD
any more. After further investigation I found that
ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but
rather ENOTTY. And since I stop getting the signal quality in case
any unknown errno value appears, this broke my signal quality query
function."
While the changes reflect what is there at:
http://comments.gmane.org/gmane.linux.kernel/1235728
it does cause regression on userspace. So, revert it to stop the
damage.

- For the 57766 and non Ax versions of 57765, bootcode needs to setup

Unfortunately, it does not have enough room in the selfboot case (i.e.
devices with no NVRAM). The driver needs to implement this.
- For performance reasons, the 2k DMA engine mode on the 57766 should
be enabled and dma size limited to 2k for standard sized packets.

On http://vladz.devzero.fr/013_ptmx-timing.php, we can see how to find
out length of a password using timestamps of /dev/ptmx. It is
documented in "Timing Analysis of Keystrokes and Timing Attacks on
SSH". To avoid that problem, do not update time when reading
from/writing to a TTY.
I am afraid of regressions as this is a behavior we have since 0.97
and apps may expect the time to be current, e.g. for monitoring
whether there was a change on the TTY. Now, there is no change. So
this would better have a lot of testing before it goes upstream.

One of the side effects of deferred probe is that some drivers which
used to be probed before initcalls completed are now happening slightly
later. This causes two problems.
- If a console driver gets deferred, then it may not be ready when
userspace starts. For example, if a uart depends on pinctrl, then the
uart will get deferred and /dev/console will not be available
- __init sections will be discarded before built-in drivers are probed.
Strictly speaking, __init functions should not be called in a drivers
__probe path, but there are a lot of drivers (console stuff again)
that do anyway. In the past it was perfectly safe to do so because all
built-in drivers got probed before the end of initcalls.
This patch fixes the problem by forcing the first pass of the deferred
list to complete at late_initcall time. This is late enough to catch the
drivers that are known to have the above issues.
