Change the indicator from 0xffffffff in the "event_id" member to
zero in the "cntr_mask" member. This removes the need to initialize
entries that are unsupported. This also solves a problem where the
number of entries in the table was increased based on a globel enum
used for all platforms, but the new unsupported entries were not added
for mips. This was leaving new table entries of all zeros that we not
marked UNSUPPORTED.

We can save an instruction in the TLB Refill path for kernel mappings
by aligning swapper_pg_dir on a 64K boundary.  The address of
swapper_pg_dir can be generated with a single LUI instead of
LUI/{D}ADDUI.

The alignment of __init_end is bumped up to 64K so there are no holes
between it and swapper_pg_dir, which is placed at the very beginning
of .bss.

The alignment of invalid_pmd_table and invalid_pte_table can be
relaxed to PAGE_SIZE.  We do this by using __page_aligned_bss, which
has the added benefit of eliminating alignment holes in .bss.

I've maintained this patch, originally from Thiemo Seufer in 2004, for a
really long time, but I think it's time for it to get a look at for
possible inclusion.  I have had no problems with it across various SGI
systems over the years.

To quote the post here:
http://www.linux-mips.org/archives/linux-mips/2004-12/msg00000.html

"the atomic functions use so far memory references for the inline
assembler to access the semaphore. This can lead to additional
instructions in the ll/sc loop, because newer compilers don't
expand the memory reference any more but leave it to the assembler.

The appended patch uses registers instead, and makes the ll/sc
arguments more explicit. In some cases it will lead also to better
register scheduling because the register isn't bound to an output
any more."

Pull i2c-embedded changes from Wolfram Sang:
 "The changes for i2c-embedded include:

   - massive rework of the omap driver
   - massive rework of the at91 driver.  In fact, the old driver gets
     removed; I am okay with this approach since the old driver was
     depending on BROKEN and its limitations made it practically
     unusable, so people used bitbanging instead.  But even if there are
     users, there is no platform_data or module parameter which would
     need to be converted.  It is just another driver doing I2C
     transfers, just way better.  Modifications of arch/arm/at91 related
     files have proper acks from the maintainer.
   - new driver for R-Car I2C
   - devicetree and generic_clock conversions and fixes
   - usual driver fixes and changes.

  The rework patches have come a long way and lots of people have been
  involved in creating/testing them.  Most patches have been in
  linux-next at least since 3.6-rc5.  A few have been added in the last
  week, I have to admit.

  An unexpected (but welcome :)) peak in private life is the cause for
  that.  The "late" patches shouldn't cause any merge conflicts and I
  will have a special eye on them during the stabilization phase.  This
  is an exception and I want to have the patches in place properly in
  time again for the next kernels."

Commit 6b8029fa ("rtc: kconfig: remove unnecessary dependencies")
removed various 'depends on RTC_CLASS' dependencies but also removed a
few 'default RTC_CLASS' statements, which actually changed default
behavior.

This resulted in the various RTC interfaces (sysfs, proc, dev) all being
disabled by default, even when RTC_CLASS is enabled:

   # CONFIG_RTC_INTF_SYSFS is not set
   # CONFIG_RTC_INTF_PROC is not set
   # CONFIG_RTC_INTF_DEV is not set

which is different from previous behavior (all of these where enabled.)

To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.

I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.

The virq_disabled flag tracks the userspace view of INTx masking
across interrupt mode changes, but we're not consistently applying
this to the interrupt and masking handler notion of the device.
Currently if the user sets DisINTx while in MSI or MSIX mode, then
returns to INTx mode (ex. rebooting a qemu guest), the hardware has
DisINTx+, but the management of INTx thinks it's enabled, making it
impossible to actually clear DisINTx.  Fix this by updating the
handler state when INTx is re-enabled.

Pull pwm changes from Thierry Reding:
 "All legacy PWM providers have now been moved to the PWM subsystem.
  The plan for 3.8 is to adapt all board files to provide a lookup table
  for PWM devices in order to get rid of the global namespace.
  Subsequently, users of the legacy pwm_request() and pwm_free()
  functions can be migrated to the new pwm_get() and pwm_put()
  functions.  Once this has been completed, the legacy API and the
  compatibility code in the core can be removed.

  In addition to the above, these changes also add support for
  configuring the polarity of a PWM signal (currently only supported on
  ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
  Managed functions to obtain and release a PWM device (devm_pwm_get()
  and devm_pwm_put()) have been added and the pwm-backlight driver has
  been updated to use them.  If the PWM subsystem hasn't been enabled,
  dummy functions are provided that allow the subsystem to safely
  compile out.

  Some common checks on input parameters have been moved to the core and
  removed from the drivers.  Finally, a small fix corrects the
  description of the PWM specifier's second cell in the device tree
  representation."

Pull scsi target updates from Nicholas Bellinger:
 "Things have been calm for the most part with no new fabric drivers in
  flight for v3.7 (we're up to eight now !), so this update is primarily
  focused on addressing a few long-standing items within target-core and
  iscsi-target fabric code.

  The highlights include:

   - target: Simplify fabric sense data length handling (roland)
   - qla2xxx: Fix endianness of task management response code (roland)
   - target: fix truncation of mode data, support zero allocation length
     (paolo)
   - target: Properly support zero-length commands in normal processing
     path (paolo)
   - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
     PDU (ronnie + nab)
   - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
     demo-mode (ronnie + nab)
   - target/file: Re-enable optional fd_buffered_io=1 operation (nab +
     hch)
   - iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
     initiator MDRSL declaration (nab)
   - target: Add target_submit_cmd_map_sgls for SGL fabric memory
     passthrough (nab + hch)
   - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
     nab)
   - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
     + hch)

  The last series for adding a new target_submit_cmd_map_sgls() fabric
  caller (as requested by hch) that accepts pre-allocated SGL memory
  (using existing logic), along with converting tcm_loop + tcm_vhost has
  only been in -next for the last days, but has gotten enough review
  +testing and is clear enough a mechanical change that I think it's
  reasonable to merge for -rc1 code.

  Thanks again to everyone who contributed this round! Extra special
  thanks to Roland (PureStorage) for tracking down the qla2xxx target
  TMR response code endian issue, and to Paolo (Redhat) for resolving
  the long standing zero-length CDB issues within target-core between
  virtual and pSCSI backends."

Pull networking updates from David Miller:

 1) UAPI changes for networking from David Howells

 2) A netlink dump is an operation we can sleep within, and therefore we
    need to make sure the dump provider module doesn't disappear on us
    meanwhile.  Fix from Gao Feng.

 3) Now that tunnels support GRO, we have to be more careful in
    skb_gro_reset_offset() otherwise we OOPS, from Eric Dumazet.

 4) We can end up processing packets for VLANs we aren't actually
    configured to be on, fix from Florian Zumbiehl.

 5) Fix routing cache removal regression in redirects and IPVS.  The
    core issue on the IPVS side is that it wants to rewrite who the
    nexthop is and we have to explicitly accomodate that case.  From
    Julian Anastasov.

 6) Error code return fixes all over the networking drivers from Peter
    Senna Tschudin.

 7) Fix routing cache removal regressions in IPSEC, from Steffen
    Klassert.

 8) Fix deadlock in RDS during pings, from Jeff Liu.

 9) Neighbour packet queue can trigger skb_under_panic() because we do
    not reset the network header of the SKB in the right spot.  From
    Ramesh Nagappa.
