1bfecd9358 ARM: board specific updates
These changes are all specific to one board only. We're trying to keep
 the number of board files low, but generally board level updates are
 ok on platforms that are working on moving towards DT based probing,
 which will eventually lead to removing them.
 
 The board-ams-delta.c board file gets a conflict between the removal of
 ams_delta_config and the addition of a lot of other data. The Kconfig
 file has two changes in the same line, and in exynos, the power domain
 cleanup conflicts with the addition of the image sensor device.

281b05392f ARM: SoC specific updates
These changes are all specific to an soc family or the code for
 one soc. Lots of work for Tegra3 this time, but also a lot of other
 platforms. There will be another (smaller) set of soc patches later in
 the merge window for stuff that has dependencies on external trees or
 that was sent just before the merge window opened.
 
 The asoc tree added a few devices to the i.mx platform, which conflict
 with other devices added in the same place here.
 
 The tegra Makefile conflicts between a number of branches, mostly because
 of changes regarding localtimer.c, which was removed in the end.

876fe76d79 mtd: maps: physmap: Add reference counter to set_vpp()
This patch is part of a set which fixes unnecessary flash erase and write errors
resulting from the MTD CFI driver turning off vpp while an erase is in progress.
This patch allows physmap_set_vpp() calls to be nested by adding a reference
counter.

omap1_set_vpp() already used a reference counter. Since it is called from
physmap_set_vpp(), omap1_set_vpp() can now be simplified.

simtec_nor_vpp() already disabled hard interrupts. Since it is called from
physmap_set_vpp(), simtec_nor_vpp() can now be simplified.

02bfc4ebbd mtd: fsmc: Move ALE, CLE defines to their respective platform
Address Latch Enable (ALE) and Command Latch Enable (CLE) defines are
platform specific and were wrongly put in driver specific fsmc.h file.
Move such defines to their respective platform.

Also instead of relying on fsmc driver, pass ALE, CLE offsets explicitly
from individual platform.

ed2d265d12 The following text was taken from the original review request:
"[RFC - PATCH 0/7] consolidation of BUG support code."
 		https://lkml.org/lkml/2012/1/26/525
 --
 
 The changes shown here are to unify linux's BUG support under
 the one <linux/bug.h> file.  Due to historical reasons, we have
 some BUG code in bug.h and some in kernel.h -- i.e. the support for
 BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h,
 but old code in kernel.h wasn't moved to bug.h at that time.  As
 a band-aid, kernel.h was including <asm/bug.h> to pseudo link them.
 
 This has caused confusion[1] and general yuck/WTF[2] reactions.
 Here is an example that violates the principle of least surprise:
 
       CC      lib/string.o
       lib/string.c: In function 'strlcat':
       lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
       make[2]: *** [lib/string.o] Error 1
       $
       $ grep linux/bug.h lib/string.c
       #include <linux/bug.h>
       $
 
 We've included <linux/bug.h> for the BUG infrastructure and yet we
 still get a compile fail!  [We've not kernel.h for BUILD_BUG_ON.]
 Ugh - very confusing for someone who is new to kernel development.
 
 With the above in mind, the goals of this changeset are:
 
 1) find and fix any include/*.h files that were relying on the
    implicit presence of BUG code.
 2) find and fix any C files that were consuming kernel.h and
    hence relying on implicitly getting some/all BUG code.
 3) Move the BUG related code living in kernel.h to <linux/bug.h>
 4) remove the asm/bug.h from kernel.h to finally break the chain.
 
 During development, the order was more like 3-4, build-test, 1-2.
 But to ensure that git history for bisect doesn't get needless
 build failures introduced, the commits have been reorderd to fix
 the problem areas in advance.

The compiler generates ARM instructions but interworking is
supported for Thumb2 kernels.

Supports both little and big endian. Unaligned loads are emitted
for ARMv6+. Not all the BPF opcodes that deal with ancillary data
are supported. The scratch memory of the filter lives on the stack.
Hardware integer division is used if it is available.

Enabled in the same way as for x86-64 and PPC64:

	echo 1 > /proc/sys/net/core/bpf_jit_enable

A value greater than 1 enables opcode output.

This is a very simple method for code running in an emulator, or under
the supervision of a debugger, to use I/O facilities on the controlling
host.

Tested with OpenOCD, and ARM's Fast Models.

Details on semihosting can be found in chapter 8 of
DUI0203I_rvct_developer_guide.pdf from ARM Ltd.

101d9b0ded ARM: use set_current_blocked() and block_sigmask()
As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check for shared signals we're about to block.

Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures.  In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Extract out the code patching code from kprobes so that it can be used
from the jump label code.  Additionally, the separated code:

 - Uses the IS_ENABLED() macros instead of the #ifdefs for THUMB2
   support

 - Unifies the two separate functions in kprobes, providing one function
   that uses stop_machine() internally, and one that can be called from
   stop_machine() directly

 - Patches the text on all CPUs only on processors requiring software
   broadcasting of cache operations

dc283d7037 ARM: 7351/1: ftrace: remove useless memory checks
Before replacing an instruction, the ftrace code determines what the old
instruction should be and verifies that that's what's really there in
memory before replacing it.  This is useful if for example a bug in
mcountrecord causes it to record wrong locations.

However, in cases where we replace call sites in entry-common.S, these
checks are not needed.  For these, we currently just memcpy() the memory
content and then "verify" it -- this is quite useless and can be
removed.

9141a003a4 ARM: 7316/1: kexec: EOI active and mask all interrupts in kexec crash path
The kexec machine crash code can be called in interrupt context via a
sysrq trigger made using the magic key combination. If the irq chip
dealing with the serial interrupt is using the fasteoi flow handler,
then we will never EOI the interrupt because the interrupt handler will
be fatal. In the case of a GIC, this results in the crash kernel not
receiving interrupts on that CPU interface.

This patch adds code (based on the PowerPC implementation) to EOI any
pending interrupts on the crash CPU before masking and disabling all
interrupts. Secondary cores are not a problem since they are placed into
a cpu_relax() loop via an IPI.

909af768e8 coredump: remove VM_ALWAYSDUMP flag
The motivation for this patchset was that I was looking at a way for a
qemu-kvm process, to exclude the guest memory from its core dump, which
can be quite large.  There are already a number of filter flags in
/proc/<pid>/coredump_filter, however, these allow one to specify 'types'
of kernel memory, not specific address ranges (which is needed in this
case).

Since there are no more vma flags available, the first patch eliminates
the need for the 'VM_ALWAYSDUMP' flag.  The flag is used internally by
the kernel to mark vdso and vsyscall pages.  However, it is simple
enough to check if a vma covers a vdso or vsyscall page without the need
for this flag.

The second patch then replaces the 'VM_ALWAYSDUMP' flag with a new
'VM_NODUMP' flag, which can be set by userspace using new madvise flags:
'MADV_DONTDUMP', and unset via 'MADV_DODUMP'.  The core dump filters
continue to work the same as before unless 'MADV_DONTDUMP' is set on the
region.

The qemu code which implements this features is at:

  http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch

In my testing the qemu core dump shrunk from 383MB -> 13MB with this
patch.

I also believe that the 'MADV_DONTDUMP' flag might be useful for
security sensitive apps, which might want to select which areas are
dumped.

This patch:

The VM_ALWAYSDUMP flag is currently used by the coredump code to
indicate that a vma is part of a vsyscall or vdso section.  However, we
can determine if a vma is in one these sections by checking it against
the gate_vma and checking for a non-NULL return value from
arch_vma_name().  Thus, freeing a valuable vma bit.

Pull PCI changes (including maintainer change) from Jesse Barnes:
 "This pull has some good cleanups from Bjorn and Yinghai, as well as
  some more code from Yinghai to better handle resource re-allocation

  There's also a new initcall_debug feature from Arjan which will print
  out quirk timing information to help identify slow quirks for fixing
  or refinement (Yinghai sent in a few patches to do just that once the
  new debug code landed).

  Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
  He's been a core PCI and Linux contributor for some time now, and has
  kindly volunteered to take over.  I just don't feel I have the time
  for PCI review and work that it deserves lately (I've taken on some
  other projects), and haven't been as responsive lately as I'd like, so
  I approached Bjorn asking if he'd like to manage things.  He's going
  to give it a try, and I'm confident he'll do at least as well as I
  have in keeping the tree managed, patches flowing, and keeping things
  stable."

4ba7c3c3c6 ARM: OMAP3+: fix oops triggered in omap_prcm_register_chain_handler(v1)
This patch fixes the oops below[1].

Obviously, the count of "struct irq_chip_generic" instances to be
allocated and setup should be irq_setup->nr_regs instead of
irq_setup->nr_regs plus one, so just fix the iterator to avoid
the oops.

[1], oops log.

9fa2df6b90 ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present
On platforms such as OMAP3, certain variants may not have IVA, SGX
or some specific component. We currently have a check to aid fixing
wrong population of OPP entries for issues such as typos. This however
causes a conflict with valid requirement where the SoC variant does
not actually have the module present.

So, reduce the severity of the print to a debug statement and skip
registering that specific OPP, but continue down the list.

68523f4233 ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer.
On OMAP4, recently a synchronisation bug is discovered by hardware
team, which leads to incorrect timer value read from 32K sync timer
IP when the IP is comming out of idle.

The issue is due to the synchronization methodology used in the SYNCTIMER IP.
The value of the counter register in 32kHz domain is synchronized to the OCP
domain register only at count up event, and if the OCP clock is switched off,
the OCP register gets out of synch until the first count up event after the
clock is switched back -at the next falling edge of the 32kHz clock.

Further investigation revealed that it applies to gptimer1 and watchdog timer2
as well which may run on 32KHz. This patch fixes the issue for all the
applicable modules.

The BUG has not made it yet to the OMAP errata list and it is applicable to
OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps.

By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU
is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces
the OCP clock to be running and allow the counter value to be updated properly
in the OCP clock domain.

The bug is going to fixed in future OMAP versions.

b2094ef840 Updates of sound stuff for 3.4-rc1
Here is the first big update chunk of sound stuff for 3.4-rc1.
 
 In the common sound infrastructure, there are a few changes for
 dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
 changes are found, as usual, in HD-audio and ASoC.
 
 Some highlights of HD-audio changes:
 - All the long-standing static quirk codes for Realtek codec were
 finally removed by fixing and extending the Realtek auto-parser.
 
 - The mute-LED control is standardized over all HD-audio codec
   drivers using the extended vmaster hook.
 
 - The vmaster slave mixer elements are initialized to 0dB as default
   so that the user won't be annoyed by the silent output after
   updates, e.g. due to the additions of new elements.
 
 - Other many fix-ups for the misc HD-audio devices.
 
 In the ASoC side, this is a very active release, including a quite a
 few framework enhancements.  Some highlights:
 
 - Support for widgets not associated with a CODEC, an important part
   of the dynamic PCM framework.
 
 - A library factoring out the common code shared by dmaengine based
   DMA drivers contributed by Lars-Peter Clausen.  This will save a lot
   of code and make it much easier to deploy enhancements to
   dmaengine.
 
 - Support for binary controls, used for providing runtime
   configuration of algorithm coefficients.
 
 - A new DAPM widget type for regulator supplies allowing drivers for
   devices that can power down unused supplies while active to do
   without any per-driver code.
 
 - DAPM widgets for DAIs, initially giving a speed boost for playback
   startup and shutdown and also the basis for CODEC<->CODEC DAI link
   support.
 
 - Support for specifying the number of significant bits on audio
   interfaces, useful for allowing applications to know how much effort
   to put into generating data for a larger sample format.
 
 - Conversion of the FSI driver used on some SH processors to
   DMAEngine.
 
 - Conversion of EP93xx drivers to DMAEngine.
 
 - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
   WM2200.
 
 - Move audmux driver from arc/arm to sound/soc
 
 - McBSP move from arch/ to sound/ and updates
 
 Also, a few small updates and fixes for other drivers like au88x0,
 ymfpci, USB 6fire, USB usx2yaudio are included.

f8974cb713 Core device tree changes for Linux v3.4
This branch contains a minor documentation addition, a utility
 function for parsing string properties needed by some of the new ARM
 platforms, disables dynamic DT code that isn't used anywhere but on a
 few PPC machines, and exports DT node compatible data to userspace via
 UEVENT properties.  Nothing earth shattering here.

c207f3a431 Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
 from Linux IRQ numbers to hardware irq numbering), generalizes it,
 renames it to irq_domain, and makes it available to all architectures.
 
 Originally the plan has been to create an all-new irq_domain
 implementation which addresses some of the powerpc shortcomings such
 as not handling 1:1 mappings well, but doing that proved to be far
 more difficult and invasive than generalizing the working code and
 refactoring it in-place.  So, this branch rips out the 'new'
 irq_domain and replaces it with the modified powerpc version (in a
 fully bisectable way of course).  It converts all users over to the
 new API and makes irq_domain selectable on any architecture.
 
 No architecture is forced to enable irq_domain, but the infrastructure
 is required for doing OpenFirmware style irq translations.  It will
 even work on SPARC even though SPARC has it's own mechanism for
 translating irqs at boot time.  MIPS, microblaze, embedded x86 and c6x
 are converted too.
 
 The resulting irq_domain code is probably still too verbose and can be
 optimized more, but that can be done incrementally and is a task for
 follow-on patches.

beeaa103ee dmaengine: at_hdmac: add slave config operation
This patch introduces DMA_SLAVE_CONFIG to at_hdmac Atmel DMA driver.

It is needed to fix a regression in the use of atmel-mci.c driver on Atmel
AT91 platforms brouth by e2b35f3:
"dmaengine/dw_dmac: Fix dw_dmac user drivers to adapt to slave_config changes"

We remove some parts of the private structure "at_dma_slave" and use the
information provided by "struct dma_slave_config": source/destination
peripheral registers and access width.

AT_DMA_SLAVE_WIDTH_* values used previously are not needed anymore as we
now use the standard ones. Although some conversion functions are needed to
match register expected values.

Some AT91 sub-architecture specific files are slightly touched by this patch
but it cannot be split because it can break compilation.

8f9c60f2e2 fbdev: sh_mipi_dsi: add extra phyctrl for sh_mipi_dsi_info
sh_mipi uses some clocks, but the method of setup depends on CPU.

Current SuperH (like sh73a0) can control all of these clocks
by CPG (Clock Pulse Generator).
It means we can control it by clock framework only.
But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS,
and only sh7372 has PHYCTRL::PLLDS.

But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was
overwrote since the callback timing of clock setting was changed
by c2658b70f0
(fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()).
To solve this issue, this patch adds extra .phyctrl.

This patch adds detail explanation for unclear mipi settings
and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

9c2b957db1 Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf events changes for v3.4 from Ingo Molnar:

 - New "hardware based branch profiling" feature both on the kernel and
   the tooling side, on CPUs that support it.  (modern x86 Intel CPUs
   with the 'LBR' hardware feature currently.)

   This new feature is basically a sophisticated 'magnifying glass' for
   branch execution - something that is pretty difficult to extract from
   regular, function histogram centric profiles.

   The simplest mode is activated via 'perf record -b', and the result
   looks like this in perf report:

	$ perf record -b any_call,u -e cycles:u branchy

	$ perf report -b --sort=symbol
	    52.34%  [.] main                   [.] f1
	    24.04%  [.] f1                     [.] f3
	    23.60%  [.] f1                     [.] f2
	     0.01%  [k] _IO_new_file_xsputn    [k] _IO_file_overflow
	     0.01%  [k] _IO_vfprintf_internal  [k] _IO_new_file_xsputn
	     0.01%  [k] _IO_vfprintf_internal  [k] strchrnul
	     0.01%  [k] __printf               [k] _IO_vfprintf_internal
	     0.01%  [k] main                   [k] __printf

   This output shows from/to branch columns and shows the highest
   percentage (from,to) jump combinations - i.e.  the most likely taken
   branches in the system.  "branches" can also include function calls
   and any other synchronous and asynchronous transitions of the
   instruction pointer that are not 'next instruction' - such as system
   calls, traps, interrupts, etc.

   This feature comes with (hopefully intuitive) flat ascii and TUI
   support in perf report.

 - Various 'perf annotate' visual improvements for us assembly junkies.
   It will now recognize function calls in the TUI and by hitting enter
   you can follow the call (recursively) and back, amongst other
   improvements.

 - Multiple threads/processes recording support in perf record, perf
   stat, perf top - which is activated via a comma-list of PIDs:

	perf top -p 21483,21485
	perf stat -p 21483,21485 -ddd
	perf record -p 21483,21485

 - Support for per UID views, via the --uid paramter to perf top, perf
   report, etc.  For example 'perf top --uid mingo' will only show the
   tasks that I am running, excluding other users, root, etc.

 - Jump label restructurings and improvements - this includes the
   factoring out of the (hopefully much clearer) include/linux/static_key.h
   generic facility:

	struct static_key key = STATIC_KEY_INIT_FALSE;

	...

	if (static_key_false(&key))
	        do unlikely code
	else
	        do likely code

	...
	static_key_slow_inc();
	...
	static_key_slow_inc();
	...

   The static_key_false() branch will be generated into the code with as
   little impact to the likely code path as possible.  the
   static_key_slow_*() APIs flip the branch via live kernel code patching.

   This facility can now be used more widely within the kernel to
   micro-optimize hot branches whose likelihood matches the static-key
   usage and fast/slow cost patterns.

 - SW function tracer improvements: perf support and filtering support.

 - Various hardenings of the perf.data ABI, to make older perf.data's
   smoother on newer tool versions, to make new features integrate more
   smoothly, to support cross-endian recording/analyzing workflows
   better, etc.

 - Restructuring of the kprobes code, the splitting out of 'optprobes',
   and a corner case bugfix.

 - Allow the tracing of kernel console output (printk).

 - Improvements/fixes to user-space RDPMC support, allowing user-space
   self-profiling code to extract PMU counts without performing any
   system calls, while playing nice with the kernel side.

 - 'perf bench' improvements

 - ... and lots of internal restructurings, cleanups and fixes that made
   these features possible.  And, as usual this list is incomplete as
   there were also lots of other improvements

9652e8bd16 ARM: SPEAr600: Add device-tree support to SPEAr600 boards
This patch adds a generic target for SPEAr600 board that can be
configured via the device-tree. Currently the following devices
are supported via the devicetree:

- VIC interrupts
- PL011 UART
- PL061 GPIO
- Synopsys DW I2C
- Synopsys DW ethernet

Other peripheral devices (e.g. SMI flash, FSMC NAND flash etc) will
follow in later patches.

Only the spear600-evb is currently supported. Other SPEAr600
based boards will follow later.

Since the current mainline SPEAr600 code only supports the SPEAr600
evaluation board, with nearly zero peripheral devices (only UART
and GPIO), it makes sense to switch over to DT based configuration
completely now. So this patch also removes all non-DT stuff, mainly
platform device data. The files spear600.c and spear600_evb.c are
removed completely.

	arch/arm/mach-ux500/devices-common.c

This adds patches from Lee Jones, Niklas Hernaeus and myself to provide
initial device tree support on the ux500 platform. The pull request from
Lee contained some other changes, so I rebased the patches on top of
the branches that are actually dependencies for this.

7e0ce270b2 ARM: ux500: db8500: list most devices in the snowball device tree
This adds all devices that are normally present through the
u8500_init_machine function in the device tree as well, which
will duplicate the devices that are visible.

This will not do much by itself because the device from the
device tree are not matched by any device driver until they
are converted as well. The next step is to move over one
device at a time to actually be used from the device tree
instead of the hardcoded device using auxdata to pass the
correct platform_data.

removes the need for the GPIO driver to have access to the system
controller registers.

a05baf335b ep93xx: Move peripheral defines to local SoC header
Move the AHB/APB peripheral defines to local SoC header since they are
only needed by the core SoC code. The UART defines are not moved
because they are used by the mach/uncompress.h header.

0fd1958050 ep93xx: Use ioremap for backlight driver
The ep93xx backlight driver uses a single register within the
framebuffer's register space. Currently the backlight driver uses a
static IO mapping for the register since the memory cannot be
requested by both drivers.

Convert the static mapping to use ioremap so that we can remove the
dependency on mach/hardware.h. To do so, we need remove the
request_mem_region from both the backlight and framebuffer drivers,
since whichever driver is loaded second will fail with -EBUSY
otherwise.

A proper fix is still required, and a FIXME comment has been added to
both drivers.
