7a28106509 ARM: tegra: don't include iomap.h from debug-macro.S
In order to move Tegra's debug-macro.S to a common location for single
zImage, it must not rely on any machine-specific header files such as
<mach/iomap.h>. Duplicate the few physical address definitions that
debug-macro.S relies upon directly into the file.

To avoid tegra_io_desc[] requiring shared knowledge of the UART
mapping's virtual address, use a virtual address outside the ranges
in tegra_io_desc[]. Call debug_ll_io_init() to propagate the mapping
beyond the early pages tables.

1a6d3da8bc ARM: tegra: decouple uncompress.h and debug-macro.S
Prior to this change, Tegra's debug-macro.S relied on uncompress.h having
determined which UART to use, and whether it was safe to use the UART
(i.e. is it not in reset, and is clocked). This determination was
communicated from uncompress.h to debug-macro.S using a few bytes of
Tegra's IRAM (an on-SoC RAM). This had the disadvantage that uncompress.h
was a required part of the kernel boot process; booting a non-compressed
kernel would not allow earlyprintk to operate.

This change duplicates the UART selection and validation logic into
debug-macro.S so that the reliance on uncompress.h is removed.

This also helps out with single-zImage work, since there is currently no
support for using any uncompress.h with single-zImage.

adc1831588 ARM: tegra: simplify DEBUG_LL UART selection options
Delete CONFIG_TEGRA_DEBUG_UART_AUTO_SCRATCH; it's not useful any more:
* No upstream bootloader currently or will ever support this option.
* CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA is a much more direct alternative.

Merge the fixed and automatic UART selection menus into a single choice
for simplicity; now you either pick AUTO_ODMDATA or a single fixed UART,
rather than potentially having an AUTO option override whatever fixed
option was chosen.

Remove TEGRA_DEBUG_UART_NONE; if you don't want a Tegra DEBUG_LL UART,
simply don't turn on DEBUG_LL. NONE used to be the default option, so
pick AUTO_ODMDATA as the new default.

c5a4d6b07a ARM: tegra: select SPARSE_IRQ
SPARSE_IRQ is required for single zImage support.

With this enabled, we can delete <mach/irqs.h>. This requires removing
one unnecessary include of that file, and hard-coding the PCIe IRQ into
the PCIe driver. This is a hack that will be dealt with as part of
converting the PCIe driver into a true DT-supporting driver.

An issue is reported in AR9462 & AR9565 that NF_cal_not_done is
not observed when HW peak detector calibration is disabled. At that
state, the HW is stuck at NF calibration which prevents tx output.
The root cause is wrong peak detector offset calibrated by HW. To
resolve this issue, peak detector calibration is done manually by SW
for AR9462 and AR9565.

f95275c48b mwl8k: Send BASTREAM firmware commands per vif
The firmware supports 8 macid's corresponding to 8 BSS that can be
created in an MBSS environment. Currently, BASTREAM commands were always
sent with macid 0. This macid is used to configure the hardware ampdu
registers with appropriate BSS address in an MBSS environment.
This mac address is used by the hardware for various ampdu related requirements
e.g. source address in BAR generation, BA interpretation e.t.c.
Using invalid macid results in this mac address not getting appropriately
configured in the hardware which results in issues during ampdu traffic.

Fix this by sending the BASTREAM commands with appropriate macid.

fa0cbbf145 mm, oom: reintroduce /proc/pid/oom_adj
This is mostly a revert of 01dc52ebdf ("oom: remove deprecated oom_adj")
from Davidlohr Bueso.

It reintroduces /proc/pid/oom_adj for backwards compatibility with earlier
kernels.  It simply scales the value linearly when /proc/pid/oom_score_adj
is written.

The major difference is that its scheduled removal is no longer included
in Documentation/feature-removal-schedule.txt.  We do warn users with a
single printk, though, to suggest the more powerful and supported
/proc/pid/oom_score_adj interface.

f4bcd79c88 ARM: SoC fixes for 3.7
We've been sitting on this longer than we meant to due to travel and
 other activities, but the number of patches is luckily not that high.
 
 Biggest changes are from a batch of OMAP bugfixes, but there are a
 few for the broader set of SoCs too (bcm2835, pxa, highbank, tegra,
 at91 and i.MX).
 
 The OMAP patches contain some fixes for MUSB/PHY on omap4 which
 ends up being a bit on the large side but needed for legacy (non-DT)
 platforms. Beyond that there are a handful of hwmod/pm changes.
 
 So, fairly noncontroversial stuff all in all, and as usual around this
 time the fixes are well targeted at specific problems.

c635a4e1c2 rcu: Separate accounting of callbacks from callback-free CPUs
Currently, callback invocations from callback-free CPUs are accounted to
the CPU that registered the callback, but using the same field that is
used for normal callbacks.  This makes it impossible to determine from
debugfs output whether callbacks are in fact being diverted.  This commit
therefore adds a separate ->n_nocbs_invoked field in the rcu_data structure
in which diverted callback invocations are counted.  RCU's debugfs tracing
still displays normal callback invocations using ci=, but displayed
diverted callbacks with nci=.

3fbfbf7a3b rcu: Add callback-free CPUs
RCU callback execution can add significant OS jitter and also can
degrade both scheduling latency and, in asymmetric multiprocessors,
energy efficiency.  This commit therefore adds the ability for selected
CPUs ("rcu_nocbs=" boot parameter) to have their callbacks offloaded
to kthreads.  If the "rcu_nocb_poll" boot parameter is also specified,
these kthreads will do polling, removing the need for the offloaded
CPUs to do wakeups.  At least one CPU must be doing normal callback
processing: currently CPU 0 cannot be selected as a no-CBs CPU.
In addition, attempts to offline the last normal-CBs CPU will fail.

This feature was inspired by Jim Houston's and Joe Korty's JRCU, and
this commit includes fixes to problems located by Fengguang Wu's
kbuild test robot.

a000b8c1e3 i2c: ocores: Add support for the GRLIB port of the controller and use function pointers for getreg and setreg functions
The registers in the GRLIB port of the controller are 32-bit and in big endian
byte order. The PRELOW and PREHIGH registers are merged into one register. The
subsequent registers have their offset decreased accordingly. Hence the register
access needs to be handled in a non-standard manner using custom getreg and
setreg functions.

Add setreg and getreg functions for different register widths and let oc_setreg
and oc_getreg use function pointers to call the appropriate functions.

A type is added as the data of the of match table entries. A new entry with a
different compatible string is added to the table. The type of that entry
triggers usage of the custom grlib functions by setting the setreg and getreg
function pointers.

Add sparc support by using platform_get_irq instead of platform_get_resource.
There are no platform resources of type IORESOURCE_IRQ for sparc, but
platform_get_irq works for sparc. In the non-sparc case platform_get_irq
internally uses platform_get_resource.

da8c66638a dlm: fix lvb invalidation conditions
When a node is removed that held a PW/EX lock, the
existing master node should invalidate the lvb on the
resource due to the purged lock.

Previously, the existing master node was invalidating
the lvb if it found only NL/CR locks on the resource
during recovery for the removed node.  This could lead
to cases where it invalidated the lvb and shouldn't
have, or cases where it should have invalidated and
didn't.

When recovery selects a *new* master node for a
resource, and that new master finds only NL/CR locks
on the resource after lock recovery, it should
invalidate the lvb.  This case was handled correctly
(but was incorrectly applied to the existing master
case also.)

When a process exits while holding a PW/EX lock,
the lvb on the resource should be invalidated.
This was not happening.

The lvb contents and VALNOTVALID flag should be
recovered before granting locks in recovery so that
the recovered lvb state is provided in the callback.
The lvb was being recovered after the lock was granted.

Commit "ARM: OMAP2+: Add device-tree support for 32kHz counter"

CONFIG_OMAP_32K_TIMER is not defined this structure generates the
following as it is not used.

Move the definition of omap_counter_match to avoid this warning when
