o After change in EPORT features of 82xx adapter, netdev->features needs to
be updated to reflect EPORT feature updates but driver was manipulating
netdev->features at wrong place.
o This patch uses netdev_update_features() and .ndo_fix_features() to
update netdev->features properly.

After resetting the device, the driver waits for a signature to be
updated to know that firmware has completed initialization. However, the
call to tg3_poll_fw() is being done too late and we're writing to the
GRC_MODE register before it has completely initialized, causing
contention with firmware. This logic has existed since day one but is
causing PCIE link to go down randomly at startup on one platform once
every few hundred reboots.
Move the tg3_poll_fw() up to before we write to the GRC_MODE register
after reset.

The exynos_adc device structure was wrongly extracted from the dev*
correcting the same.
Using the regular conversion of
struct device* -> struct platform_device* -> struct exynos_adc* seems wrong.
Instead we should be doing
struct device* -> struct iio_dev* -> struct exynos_adc*

This patch fixes below build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m:

make: *** [vmlinux] Error 1
When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.
The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

Commit d3f79584a8 ("ARM: cleanup undefined instruction entry code")
improved the register scheduling when handling undefined instructions.
A side effect of this is that r5 is now used as a temporary, whilst the
VFP probing code relies on r5 containing a non-zero value when VFP is
not supported.
This patch fixes the VFP detection code so that we don't rely on the
contents of r5. Without this patch, Linux dies loudly on CPUs without
VFP support.

If one reads /proc/$PID/smaps, the mmap_sem belonging to the
address space of the task being examined is locked for reading.
All the pages of the vmas belonging to the task's address space
are then walked with this lock held.
If a gate_vma is present in the architecture, it too is examined
by the fs/proc/task_mmu.c code. As gate_vma doesn't belong to the
address space of the task though, its pages are not walked.
A recent cleanup (commit f6604efe) of the gate_vma initialisation
code set the vm_mm value to &init_mm. Unfortunately a non-NULL
vm_mm value in the gate_vma will cause the task_mmu code to attempt
to walk the pages of the gate_vma (with no mmap-sem lock held). If
one enables Transparent Huge Page support and vm debugging, this
will then cause OOPses as pmd_trans_huge_lock is called without
mmap_sem being locked.
This patch removes the .vm_mm value from gate_vma, restoring the
original behaviour of the task_mmu code.

virt_to_page() is typically implemented as a macro containing a cast so
that it will accept both pointers and unsigned long without causing a
warning.
But MIPS virt_to_page() uses virt_to_phys which is a function so passing
an unsigned long will cause a warning:
CC mm/page_alloc.o
mm/page_alloc.c: In function ‘free_reserved_area’:
mm/page_alloc.c:5161:3: warning: passing argument 1 of ‘virt_to_phys’ makes pointer from integer without a cast [enabled by default]

At the moment wait_event_timeout/wait_event_interruptible_timeout may
time out 1 jiffy too early, as the calculated expiry time is 1 less than
needed. Besides timing out too early this also means that the
calculation of the remaining time will be incorrect and we will pass a
non-zero remaining time to user space in case of a time out. This is one
reason for the following bugzilla report:

We need this to avoid premature timeouts whenever scheduling a timeout
based on the current jiffies value. For an explanation see [1].
The following patches will take the helper into use.
Once the more generic solution proposed in the thread at [1] is accepted
this patch can be reverted while keeping the follow-up patches.

As multiplatform build is being adopted by more and more ARM platforms, initcall
function should be used very carefully. For example, when both arm_big_little_dt
and cpufreq-cpu0 drivers are compiled in, arm_big_little_dt driver may try to
register even if we had platform device for cpufreq-cpu0 registered.
To eliminate this undesired the effect, the patch changes arm_big_little_dt
driver to have it instantiated as a platform_driver. Then it will only run on
platforms that create the platform_device "arm-bL-cpufreq-dt".

If arm_big_little_dt driver is enabled, then it will always try to register with
big LITTLE cpufreq core driver. In case DT doesn't have relevant data for cpu
nodes, i.e. operating points aren't present, then we should exit early and
shouldn't register with big LITTLE cpufreq core driver. Otherwise we will fail
continuously from the driver->init() routine.
This patch fixes this issue.

- As suggested by Gleb, wrap calls to gfn_to_pfn() with srcu_read_lock/unlock().
Memory slots should be acccessed from a SRCU read section.
- kvm_mips_map_page() now returns an error code to it's callers, instead of
calling panic() if it cannot find a mapping for a particular gfn.

Currently the driver's assumed behavior for a modeset with an attached
FB is that the corresponding connector will be switched to DPMS ON mode
if it happened to be in DPMS OFF (or another power save mode). This
wasn't enforced though if only the FB changed, everything else (format,
connector etc.) remaining the same. In this case we only set the new FB
base and left the connector in the old power save mode.
Fix this by forcing a full modeset whenever there is an attached FB and
any affected connector is in a power save mode.
V_2: Run the test for encoders in power save mode outside the the
test for fb change: user space may have just disabled the encoders
but left everything else in place. Make sure the connector list is
not empty before running this test.

This patch updates the marzen board code as if USB PHY isn't enabled
they phy will have a value set by ERR_PTR() rather than be NULL.
Without this patch a NULL pointer dereference and kernel panic
occurs on initialisation of USB on marzen.
This resolves a regression introduced in 3.10-rc1 by
b7fa5c2aec
("usb: phy: return -ENXIO when PHY layer isn't enabled").

free_irq() expects the same pointer that was passed to request_threaded_irq(),
otherwise the IRQ is not freed.

local_irq_enable() may expand into very different code, so it rather should
stay in C. Also this keeps the assembler code size constant which keeps
the rollback code simple. So it's best to split r4k_wait into two parts,
one C and one assembler.
Finally add the local_irq_enable() to r4k_wait to ensure the WAIT
instruction in __r4k_wait() will work properly.
