====================
pull-request: can 2014-07-25
this is a pull request of one patch for the net tree, hoping to get into the
3.16 release.
The patch by George Cherian fixes a regression in the c_can platform driver.
When using two interfaces the regression leads to a non function second
interface.

When a memory bitmap is fully populated on a large memory
machine (several TB of RAM) it can take more than a minute
to walk through all bits. This causes the soft lockup
detector on these machine to report warnings.
Avoid this by touching the soft lockup watchdog in the
memory bitmap walking code.

The radix tree implementatio is proved to work the same as
the old implementation now. So the old implementation can be

The existing implementation of swsusp_free iterates over all
pfns in the system and checks every bit in the two memory
bitmaps.
This doesn't scale very well with large numbers of pfns,
especially when the bitmaps are not populated very densly.
Change the algorithm to iterate over the set bits in the
bitmaps instead to make it scale better in large memory
configurations.
Also add a memory_bm_clear_current() helper function that
clears the bit for the last position returned from the
memory bitmap.

Add a function to find a bit in the radix tree for a given

This moves the espfix64 logic into native_iret. To make this work,
it gets rid of the native patch for INTERRUPT_RETURN:
INTERRUPT_RETURN on native kernels is now 'jmp native_iret'.
This changes the 16-bit SS behavior on Xen from OOPSing to leaking
some bits of the Xen hypervisor's RSP (I think).
[ hpa: this is a nonzero cost on native, but probably not enough to
measure. Xen needs to fix this in their own code, probably doing
something equivalent to espfix64. ]

In commit f814f9ac5a ("spi/orion: add device tree binding"), Device
Tree support was added to the spi-orion driver. However, this commit
reads the "cell-index" property, without taking into account the fact
that DT properties are big-endian encoded.
Since most of the platforms using spi-orion with DT have apparently
not used anything but cell-index = <0>, the problem was not
visible. But as soon as one starts using cell-index = <1>, the problem
becomes clearly visible, as the master->bus_num gets a wrong value
(actually it gets the value 0, which conflicts with the first bus that
has cell-index = <0>).
This commit fixes that by using of_property_read_u32() to read the
property value, which does the appropriate endianness conversion when
needed.

Intel Wired LAN Driver Updates 2014-07-25
This series contains updates to e1000e, ixgbe and ixgbevf.
Mark provides all the changes for ixgbe and ixgbevf. Converts some udelay()
calls to the preferred usleep_range(). Fixes a spurious release of the
semaphore in several functions when there was a failure to acquire the
semaphore in the first place. Fixes a X540 semaphore error where an
incorrect check was treating success as failure and vice-versa. Fixed
ixgbe_write_mbx() error when it was being called and there was no
mbx->ops.write method defined, so no error code was returned. The
corresponding read function would explicitly return an error in such a
case as do other functions. Cleans up unused (dead) code by removing it.
Finally make return values more direct, eliminating some gotos and
otherwise unneeded conditionals, which allows the removal of some local
variables.
David provides all the changes for e1000e. Fix CRC errors with jumbo
traffic for 82579, i217 and i218 client parts to increase the gap
between the read and write pointers in the transmit FIFO. Added code
to check and respond to previously ignored return values from NVM
access functions. Added support for EEE in Sx states and fixed EEE in
S5 with runtime PM enabled.

By writing zero to both the active and idle cycle times the maXTouch device
is put into a deep sleep mode when it consumes minimal power. It is
unnecessary to change the configuration of any other objects (for example
to disable T9 touchscreen).
It is counterproductive to reset the chip on resume, it will result in a
long delay. However it is necessary to issue a calibrate command after the
chip has spent any time in deep sleep.
This patch also deals with the situation where the power configuration is
zero on probe, which would mean that the device never wakes up to execute
commands.

Today the instruction emulator can get called via 2 separate code paths. It
can either be called by MMIO emulation detection code or by privileged

This is bad, as both code paths prepare the environment differently. For MMIO

there don't have to actually fetch that information.
