pcie_bus_configure_settings() makes sure the MPS across the bus is uniform

firmware to program these PCIe settings for the OS.

9c98666163 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation
When configure kprobe events of ftrace with "stacktrace" option enabled
in arm, there is no stacktrace was recorded after the kprobe event was
triggered. The root cause is no save_stack_trace_regs() function implemented.

Implement the save_stack_trace_regs() function in arm, then ftrace will
call this architecture-related function to record the stacktrace into
ring buffer.

After this fix, stacktrace can be recorded, for example:

 # mount -t debugfs nodev /sys/kernel/debug
 # echo "p:netrx net_rx_action" >> /sys/kernel/debug/tracing/kprobe_events

3780f7ab49 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction
We will reach fixup handler when one thread(say cpu0) caused an undefined exception, while another thread(say cpu1) is unmmaping the page.

Fixup handler returns to the next userspace instruction which has caused the undef execption, rather than going to the same instruction.

ARM ARM says that after undefined exception, the PC will be pointing
to the next instruction. ie +4 offset in case of ARM and +2 in case of Thumb

And there is no correction offset passed to vector_stub in case of
undef exception.

File: arch/arm/kernel/entry-armv.S +1085
vector_stub     und, UND_MODE

During an undefined exception, in normal scenario(ie when ldrt
instruction does not cause an abort) after resorting the context in
VFP hardware, the PC is modified as show below before jumping to
ret_from_exception which is in r9.

File: arch/arm/vfp/vfphw.S +169
@ The context stored in the VFP hardware is up to date with this thread
vfp_hw_state_valid:
   tst     r1, #FPEXC_EX
   bne     process_exception     @ might as well handle the pending
                                 @ exception before retrying branch
                                 @ out before setting an FPEXC that
                                 @ stops us reading stuff
        VFPFMXR FPEXC, r1        @ Restore FPEXC last
        sub     r2, r2, #4       @ Retry current instruction - if Thumb
        str     r2, [sp, #S_PC]  @ mode it's two 16-bit instructions,
                                 @ else it's one 32-bit instruction, so
                                 @ always subtract 4 from the following
                                 @ instruction address.

But if ldrt results in an abort, we reach the fixup handler and return
to ret_from_execption without correcting the pc.

This patch modifes the fixup handler to re-execute the same instruction which caused undefined execption.

060bf2af12 ARM: l2c: vexpress ca9x4: move L2 cache initialisation earlier
It is beneficial to have the L2 cache up and running earlier in the
system boot.  Not only will this allow for simpler code when we come to
enable some features, but it also means that we get a more accurate
bogomips value for the udelay() loop.  Calibrating the loop with the
L2 cache off, and then running with the L2 cache on is not the best
idea.

99ca1772e5 ARM: l2c: implement L2C-310 erratum 727915 as a method override
Implement L2C-310 erratum 727915 by overriding the flush_all method
in the outer_cache operations structure.  This allows us to sensibly
contain the erratum code in one place without affecting other
locations or implementations.

6a28cf59ff ARM: l2c: add L2C-210 specific handlers
Add L2C-210 specific cache operation handlers.  These are tailored to
the requirements of the L2C-210 cache controller, which doesn't
require any workarounds.  We avoid using the way operations during
normal operation, which means we can avoid locking: the only time
we use the way operations are during initialisation, and when
disabling the cache.

da3627fbda ARM: l2c: group implementation specific code together
Back in the mists of time, someone decided that it would be a good idea
to group like functions together - so all the save functions in one
place, all the resume functions in another, all the OF parsing functions
some place else.

This makes it difficult to get an overview on what a particular
implementation is doing - grouping an implementations specific functions
together makes more sense, because you can see what it's doing without
the clutter of other implementations.

Rather than having a boolean and other tricks to disable some bits of

between OF and non-OF, and the non-OF part.

The common part can take a block of function pointers, and the cache
ID (to cope with Aurora's DT specified ID.)  Eliminate the redundant
setting of l2x0_base in the OF case, moving it to the non-OF init
function.

On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.

Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.

This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

3f8517e793 ARM: 8063/1: bL_switcher: fix individual online status reporting of removed CPUs
The content of /sys/devices/system/cpu/cpu*/online  is still 1 for those
CPUs that the switcher has removed even though the global state in
/sys/devices/system/cpu/online is updated correctly.

It turns out that commit 0902a9044f ("Driver core: Use generic
offline/online for CPU offline/online") has changed the way those files
retrieve their content by relying on on the generic attribute handling
code.  The switcher, by calling cpu_down() directly, bypasses this
handling and the attribute value doesn't get updated.

Fix this by calling device_offline()/device_online() instead.

Move the panel/encoder driver compatible-string converter from
arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical
place for it, as it's really an omapdss internal hack.

The code is rewritten to follow the video node graph, starting from
omapdss. This removes the need to have the device compatible-string
database.

a43ae58c84 PCI: Turn pcibios_penalize_isa_irq() into a weak function
pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA
is not used by some architectures.  Make pcibios_penalize_isa_irq() a
__weak function to simplify the code.  This removes the need for new
platforms to add stub implementations of pcibios_penalize_isa_irq().

99ffa6425f ARM: dts: am437x-gp-evm: add support for parallel NAND flash
Adds pinmux and DT node for Micron (MT29F4G08AB) x8 NAND device present on
am437x-gp-evm board.
(1) As NAND Flash data lines are muxed with eMMC, Thus at a given time either
    eMMC or NAND can be enabled. Selection between eMMC and NAND is controlled:
    (a) By dynamically driving following GPIO pin from software
        SPI2_CS0(GPIO) == 0 NAND is selected (default)
        SPI2_CS0(GPIO) == 1 eMMC is selected
    (b) By statically using Jumper (J89) on the board

(2) As NAND device connnected to this board has page-size=4K and oob-size=224,
    So ROM code expects boot-loaders to be flashed in BCH16 ECC scheme for
    NAND boot.

ded79bebca ARM: dts: keystone: update reset node to work with reset driver
The pll controller register set and device state control registers
include sets of registers with different purposes, so it's logically
to add syscon entry to be able to access them from appropriate places.

So added pll controller and device state control syscon entries.

The keystone driver requires the next additional properties:

"ti,syscon-pll" - phandle/offset pair. The phandle to syscon used to
		  access pll controller registers and the offset to use
		  reset control registers.

"ti,syscon-dev" - phandle/offset pair. The phandle to syscon used to
		  access device state control registers and the offset
		  in order to use mux block registers for all watchdogs.

"ti,wdt-list"	- option to declare what watchdogs are used to reboot
		  the SoC, so set "0" WDT as default.

84cc8a7114 Quite a lot changes but it looks like DT approach is really paying off.
BG2Q joins Berlin SoC family with corresponding development board, DW
 gpio nodes for all SoCs. Most notably, we have settled clock bindings
 to allow us to continue on drivers requiring clocks and pinctrl bindings.
 Last but not least, BG2Q gained SDHCI support and is able to properly
 boot into userspace.

2ca602de42 PM related fixes for omap3 that were discovered during omap3
conversion to device tree. This series sets up the PMIC signaling
 in a way where we can test for PM regressions easily by
 looking at state of the the sys_clkreq and sys_off_mode pins.
 
 Note that this series alone does not make omap3 PM to cut
 off core voltage during off-idle, changes to twl4030-power.c
 configurations are still needed. Those will be posted
 separately.

b33cdd283b ARM: vexpress: refine dependencies for new code
The versatile express changes for 3.16 introduced a number of
build regressions for randconfig kernels by not tracking dependencies
between the components right.

This patch tries to rectify that:

* the mach-vexpress code cannot link without the syscfg driver,
  which in turn needs MFD_VEXPRESS_SYSREG
* various drivers call devm_regmap_init_vexpress_config(), which
  has to be exported so it can be used by loadable modules
* the configuration bus uses OF DT helper functions that are not
  available to platforms disable CONFIG_OF
* The sysreg driver exports GPIOs through gpiolib, which can
  be disabled on some platforms.
* The clocksource code cannot be built on platforms that don't
  use modern timekeeping but rely on gettimeoffset.

0e0779da22 ARM: 8053/1: kernel: sleep: restore HYP mode configuration in cpu_resume
On CPUs with virtualization extensions the kernel installs HYP mode
configuration on both primary and secondary cpus upon cold boot.

On platforms where CPUs are shutdown in idle paths (ie CPU core gating),
when a CPU resumes from low-power states it currently does not execute
code that reinstalls the HYP configuration, which means that the kernel
cannot run eg KVM properly on such machines.

This patch, mirroring cold-boot behaviour, executes position independent
code that reinstalls HYP configuration and drops to SVC mode safely on
warmboot, so that deep idle states can be enabled in kernel running as
hosts on platforms with power management HW.

72e6ae285a ARM: 8043/1: uprobes need icache flush after xol write
After instruction write into xol area, on ARM V7
architecture code need to flush dcache and icache to sync
them up for given set of addresses. Having just
'flush_dcache_page(page)' call is not enough - it is
possible to have stale instruction sitting in icache
for given xol area slot address.

Introduce arch_uprobe_ixol_copy weak function
that by default calls uprobes copy_to_page function and
than flush_dcache_page function and on ARM define new one
that handles xol slot copy in ARM specific way

flush_uprobe_xol_access function shares/reuses implementation
with/of flush_ptrace_access function and takes care of writing
instruction to user land address space on given variety of
different cache types on ARM CPUs. Because
flush_uprobe_xol_access does not have vma around
flush_ptrace_access was split into two parts. First that
retrieves set of condition from vma and common that receives
those conditions as flags.

Note ARM cache flush function need kernel address
through which instruction write happened, so instead
of using uprobes copy_to_page function changed
code to explicitly map page and do memcpy.

Note arch_uprobe_copy_ixol function, in similar way as
copy_to_user_page function, has preempt_disable/preempt_enable.

166aaf3966 ARM: 8029/1: mcpm: Rename the power_down_finish() functions to be less confusing
The name "power_down_finish" seems to be causing some confusion,
because it suggests that this function is responsible for taking
some action to cause the specified CPU to complete its power down.

This patch renames the affected functions to "wait_for_powerdown"
and similar, since this function's intended purpose is just to wait
for the hardware to finish a powerdown initiated by a previous
cpu_power_down.

483a6c9d44 ARM: 8064/1: fix v7-M signal return
According to the ARM ARM, the behaviour is UNPREDICTABLE if the PC read
from the exception return stack is not half word aligned.  See the
pseudo code for ExceptionReturn() and PopStack().

The signal handler's address has the bit 0 set, and setup_return()
directly writes this to regs->ARM_pc.  Current hardware happens to
discard this bit, but QEMU's emulation doesn't and this makes processes
crash.  Mask out bit 0 before the exception return in order to get
predictable behaviour.

8203d5b628 ARM: 8052/1: unwind: Fix handling of "Pop r4-r[4+nnn],r14" opcode
The arm EABI states that unwind opcode 10100nnn means pop register r4-4[4+nnn],aditionally there is a similar unwind opcode: 10101nnn which means the same thing plus popping r14. Those two cases are handled by the unwind_exec_pop_r4_to_rN function which checks whether the 4th bit is set and does r14 popping.

However, up until now it has been checking whether the 8th bit was set (mask & 0x80) instead of the 4th (mask & 0x8), a simple to make typo but this meant that we were always popping r14 even if we had the former opcode.

This patch changes the mask so that the 2 unwind opcodes are being handled correctly.

85f9f90808 ARM: EXYNOS: Use the cpu_pm notifier for pm
Use the cpu_pm_enter/exit notifier to group some pm code inside the
pm file.

The save and restore code is duplicated across pm.c and cpuidle.c. By
using the cpu_pm notifier, we can factor out the routine.

4073f94269 [media] ARM: S5PV210: Remove camera support from mach-goni.c
S5PV210 is going to get DT support, so we can remove the camera
bits from the only board using camera on S5PV210. This allows to
clean the exynos4-is driver by dropping code for non-dt platforms.
This patch can be dropped if a patch removing the whole board
file is applied first.

Merge "ARM: STi: DT changes for v3.16, v3" from Maxime Coquelin:

Please consider these STi DT updates for v3.16.

This 3rd version takes into account Olof's comments on the v2:
        - Fix upper-cases in labels and node names
        - Sort compatibles order from specific to generic
        - Sort dts entries in Makefile

It also adds support for the B2020 revision E board for STiH416 SoC.

Note that two reset patches are part of this pull request, in order to avoid
compilation breakage.
Adding these two patches in this pull request has been accepted by Philipp Zabel.
