Currently the march flag gets only passed to C files, but not to
assembler files.
This means that we can't add new instructions like e.g. aghik to asm
files, since the assembler doesn't know of the new instructions if
the appropriate march flag isn't specified.

So also pass the march flag when compiling assembler files as well.

If gettimeofday / clock_gettime are called multiple times in a row
the STCK instruction will stall until a difference in the result is
visible. This unnecessarily slows down the vdso calls, use stcke
instead of stck to get rid of the stall.

pull request: wireless 2014-09-05

Please pull this batch of fixes intended for the 3.17 stream...

For the mac80211 bits, Johannes says:

"Here are a few fixes for mac80211. One has been discussed for a while
and adds a terminating NUL-byte to the alpha2 sent to userspace, which
shouldn't be necessary but since many places treat it as a string we
couldn't move to just sending two bytes.

In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
fix for the recently introduced RX aggregation offload, a revert for
a broken patch (that luckily didn't really cause any harm) and a small
fix for alignment in debugfs."

For the iwlwifi bits, Emmanuel says:

"I revert a patch that disabled CTS to self in dvm because users
reported issues. The revert is CCed to stable since the offending
patch was sent to stable too. I also bump the firmware API versions
since a new firmware is coming up. On top of that, Marcel fixes a
bug I introduced while fixing a bug in our Kconfig file."

Please let me know if there are problems!

It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.

What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.

Commit 0244756e ("ufs: sb mutex merge + mutex_destroy") introduces
deadlocks in ufs_new_inode() and ufs_free_inode().
Most callers of that functions acqure the mutex by themselves and
ufs_{new,free}_inode() do that via lock_ufs(),
i.e we have an unavoidable double lock.

The patch proposes to resolve the issue by making sure that
ufs_{new,free}_inode() are not called with the mutex held.

Pull xfs fixes from Dave Chinner:
 "The fixes all address recently discovered data corruption issues.

  The original Direct IO issue was discovered by Chris Mason @ Facebook
  on a production workload which mixed buffered reads with direct reads
  and writes IO to the same file.  The fix for that exposed other issues
  with page invalidation (exposed by millions of fsx operations) failing
  due to dirty buffers beyond EOF.

  Finally, the collapse_range code could also cause problems due to
  racing writeback changing the extent map while it was being shifted
  around.  The commits for that problem are simple mitigation fixes that
  prevent the problem from occuring.  A more robust fix for 3.18 that
  addresses the underlying problem is currently being worked on by
  Brian.

   - a direct IO read/buffered read data corruption

The update_walltime() code works on the shadow timekeeper to make the
seqcount protected region as short as possible. But that update to the
shadow timekeeper does not update all timekeeper fields because it's
sufficient to do that once before it becomes life. One of these fields
is tkr.base_mono. That stays stale in the shadow timekeeper unless an
operation happens which copies the real timekeeper to the shadow.

The update function is called after the update calls to vsyscall and
pvclock. While not correct, it did not cause any problems because none
of the invoked update functions used base_mono.

commit cbcf2dd3 (x86: kvm: Make kvm_get_time_and_clockread()
nanoseconds based) changed that in the kvm pvclock update function, so
the stale mono_base value got used and caused kvm-clock to malfunction.

Put the update where it belongs and fix the issue.

The error handling in compat_sys_nanosleep() is correct, but
completely non obvious. Document it and restrict it to the
-ERESTART_RESTARTBLOCK return value for clarity.

amd-xgbe: AMD XGBE driver fixes 2014-09-05

The following series of patches includes fixes to the driver.

- Proper access to 64 bit management counter registers
- Enable all management counter registers to generate an interrupt when
  the counter threshold is reached

This patch series is based on net.

As the management counters reach a threshold they will generate an
interrupt so the value can be saved and the counter reset. The
current code does not enable this interrupt on all counters. This
can result in inaccurate statistics.

Update the code to enable all the counters to generate an interrupt
when its threshold is exceeded.

Even if the management counters are configured to be 32 bit register
values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are
always 64 bit counter registers.  Since they are not being treated as
64 bit values, these statistics are being reported incorrectly (ifconfig,
ethtool, etc.).

Update the routines used to read the registers to access the "hi"
register (an offset of 4 from the "lo" register) to create a 64 bit
value for these 64 bit counters.

This patch does not affect the 10/100 GRETH MAC.

Before all GBit GRETH TX descriptor ring cleaning was done in
start_xmit(), when descriptor list became full it activated
TX interrupt to start the NAPI rx poll function to do TX ring
cleaning.

With this patch the TX descriptor ring is always cleaned from
the NAPI rx poll function, triggered via TX or RX interrupt.
Otherwise we could end up in TX frames being sent but not
reported to the stack being sent. On the 10/100 GRETH this
is not an issue since the SKB is copied&aligned into private
buffers so that the SKB can be freed directly on start_xmit()

The cnic module needs to ensure that if ipv6 support is compiled as a module,
then the cnic module cannot be compiled as built-in as it depends on ipv6.
Made this check cleaner via Kconfig

Use simpler IS_ENABLED for CONFIG_VLAN_8021Q check

ahci_xgene: Fix the link down in first attempt for the APM X-Gene SoC AHCI SATA host controller driver.

Due to HW errata the APM X-Gene AHCI SATA host controller reports link
down even if the device presence is detected. This issue is due to speed
negotiation failure. This patch implements the algorithm to retry the
COMRESET if PxSTAT register reports device presence detected but
PHY communication not established. The maximum retry attempts are 3.

This patch also fixes the code to match the algorithm for the printing
a warning message if the disparity error still exists after link up.

This patch implements the feature to skip the PHY and clock
initialization if it is already configured by the firmware.
