The patch introduces additional flag EEH_PE_RESET to indicate the
corresponding PE is under reset. In turn, the PE retrieval bakcend
on PowerNV platform can return unfrozen state for the EEH core to
moving forward. Flag EEH_PE_CFG_BLOCKED isn't the correct one for
the purpose.
In PCI passthrou case, the problem is more worse: Guest doesn't
recover 6th EEH error. The PE is left in isolated (frozen) and
config blocked state on Broadcom adapters. We can't retrieve the
PE's state correctly any more, even from the host side via sysfs
/sys/bus/pci/devices/xxx/eeh_pe_state.

IRQ support for Broadcom's bus-axi driver bcma was merged into John
Linville's wireless tree and will show up in 3.19. This patch makes use
of this feature in the DTS file for the the BCM5301X SoCs. I left the
PCIe controller out, because this still needs some discussion.

The function graph helper function prepare_ftrace_return() which does the work
to hijack the parent pointer has that parent pointer as its first parameter.
Instead, if we make it the second parameter and have ip as the first parameter
(self_addr), then it can use the %rdi from save_mcount_regs that loads it
already.

The save_mcount_regs macro saves and restores the required mcount regs that
need to be saved before calling C code. It is done for all the function hook
utilities (static tracing, dynamic tracing, regs, function graph).
When frame pointers are enabled, the ftrace trampolines need to set up
frames and pointers such that a back trace (dump stack) can continue passed
them. Currently, a separate macro is used (create_frame) to do this, but
it's only done for the ftrace_caller and ftrace_reg_caller functions. It
is not done for the static tracer or function graph tracing.
Instead of having a separate macro doing the recording of the frames,
have the save_mcount_regs perform this task. This also has all tracers
saving the frame pointers when needed.

mcount regs
The macro save_mcount_regs saves regs onto the stack. But to uncouple the
amount of stack used in that macro from the users of the macro, we need
to have a define that tells all the users how much stack is used by that
macro. This way we can change the amount of stack the macro uses without
breaking its users.
Also remove some dead code that was left over from commit fdc841b58cf5
"ftrace: x86: Remove check of obsolete variable function_trace_stop".

Currently save_mcount_regs is passed a "skip" parameter to know how much
stack updated the pt_regs, as it tries to keep the saved pt_regs in the
same location for all users. This is rather stupid, especially since the
part stored on the pt_regs has nothing to do with what is suppose to be
in that location.
Instead of doing that, just pass in an "added" parameter that lets that
macro know how much stack was added before it was called so that it
can get to the RIP. But the difference is that it will now offset the
pt_regs by that "added" count. The caller now needs to take care of
the offset of the pt_regs.
This will make it easier to simplify the code later.

Instead of having save_mcount_regs store the RIP in %rdx as a temp register
to place it in the proper location of the pt_regs on the stack. Use the
%rdi register as the temp register. This lets us remove the extra store
in the ftrace_caller_setup macro.

The name MCOUNT_SAVE_FRAME is rather confusing as it really isn't a
function frame that is saved, but just the required mcount registers
that are needed to be saved before C code may be called. The word
"frame" confuses it as being a function frame which it is not.
Rename MCOUNT_SAVE_FRAME and MCOUNT_RESTORE_FRAME to save_mcount_regs
and restore_mcount_regs respectively. Noticed the lower case, which
keeps it from screaming at the reviewers.

Linus pointed out that there were locations that did the hard coded
update of the parent and rip parameters. One of them was the static tracer
which could also use the ftrace_caller_setup to do that work. In fact,
because it did not use it, it is prone to bugs, and since the static
tracer is hardly ever used (who wants function tracing code always being
called?) it doesn't get tested very often. I only run a few "does it still
work" tests on it. But I do not run stress tests on that code. Although,
since it is never turned off, just having it on should be stressful enough.
(especially for the performance folks)
There's no reason that the static tracer can't also use ftrace_caller_setup.
Have it do so.

This patch plumbs the existing ARM IOMMU DMA infrastructure (which isn't
actually called outside of a few drivers) into arch_setup_dma_ops, so
that we can use IOMMUs for DMA transfers in a more generic fashion.
Since this significantly complicates the arch_setup_dma_ops function,
it is moved out of line into dma-mapping.c. If CONFIG_ARM_DMA_USE_IOMMU
is not set, the iommu parameter is ignored and the normal ops are used
instead.

When we generate the instruction for out of line execution the length
of the to be copied instruction was evaluated from a not initialized
memory location.
Therefore we ended up with a random (2, 4 or 6) number of bytes being

This works surprisingly well most of the time, but still not always.

First, there was this: https://bugzilla.kernel.org/show_bug.cgi?id=88001
The problem there was that microcode patches are not being reapplied
after suspend-to-ram. It was important to reapply them, though, because
of for example Haswell's TSX erratum which disabled TSX instructions
with a microcode patch.
A simple fix was fb86b97300d9 ("x86, microcode: Update BSPs microcode
on resume") but, as it is often the case, simple fixes are too
simple. This one causes 32-bit resume to fail:
https://bugzilla.kernel.org/show_bug.cgi?id=88391
Properly fixing this would require more involved changes for which it
is too late now, right before the merge window. Thus, limit this to
64-bit only temporarily.

The Armada XP has multiple cores clocked by independent clocks. The
SMP startup code contains a function called set_secondary_cpus_clock()
called in armada_xp_smp_prepare_cpus() to ensure the clocks of the
secondary CPUs match the clock of the boot CPU.
With the introduction of suspend/resume, this operation is no longer
needed when booting the system, but also when existing the suspend to
RAM state. Therefore this commit reworks a bit the logic: instead of
configuring the clock of all secondary CPUs in
armada_xp_smp_prepare_cpus(), we do it on a per-secondary CPU basis in
armada_xp_boot_secondary(), as this function gets called when existing
suspend to RAM for each secondary CPU.
Since the function now only takes care of one CPU, we rename it from
set_secondary_cpus_clock() to set_secondary_cpu_clock(), and it looses
its __init marker, as it is now used beyond the system initialization.
Note that we can't use smp_processor_id() directly, because when
exiting from suspend to RAM, the code is apparently executed with
preemption enabled, so smp_processor_id() is not happy (prints a
warning). We therefore switch to using get_cpu()/put_cpu(), even
though we pretty much have the guarantee that the code starting the
secondary CPUs is going to run on the boot CPU and will not be
migrated.

The armada_370_xp_cpu_resume() until now was used only as the function
called by the SoC when returning from a deep idle state (as used in
cpuidle, or when the CPU is brought offline using CPU hotplug).
However, it is now also used when exiting the suspend to RAM state. In
this case, it is the bootloader that calls back into this function,
with the MMU left enabled by the BootROM. Having the MMU enabled when
entering this function confuses the kerrnel because we are not using
the kernel page tables at this point, but in other mvebu functions we
use the information on whether the MMU is enabled or not to find out
whether we should talk to the coherency fabric using a physical
address or a virtual address. To fix that, we simply disable the MMU
when entering this function, so that the kernel is in an expected
situation.

On the Armada XP GP platform, entering suspend to RAM state is
triggering by talking to an external PIC micro-controller connected to
the SoC using 3 GPIOs. There is then a small magic sequence of GPIO
toggling that needs to be used to tell the PIC to turn off the SoC.
The code uses the Device Tree to find out which GPIOs are used to
connect to the PIC micro-controller, and then registers its
mvebu_armada_xp_gp_pm_enter() callback to the SoC-level PM code. The
SoC PM code will call back into this registered function at the very
end of the suspend procedure.

When going out of suspend to RAM, the Marvell EBU platforms go through
the bootloader, which re-configures the DRAM controller. To achieve
this, the bootloader executes a piece of code called the "DDR3
training code". It does some reads/writes to the memory to find out
the optimal timings for the memory chip being used.
This has the nasty side effect that the first 10 KB of each DRAM
chip-select are overwritten by the bootloader when exiting the suspend
to RAM state.
Therefore, this commit implements the ->reserve() hook for the 'struct
machine_desc' used on Armada XP, to reserve the 10 KB of each DRAM
chip-select using the memblock API.

This commit implements the core of the platform code to enable
suspend/resume on Armada XP. It registers the platform_suspend_ops
structure, and implements the ->enter() hook of this structure.
It is worth mentioning that this commit only provides the SoC-level
part of suspend/resume, which calls into some board-specific code
provided in a follow-up commit.
The most important thing that this SoC-level code has to do is to
build an in-memory structure that contains a magic number, the return
address in the kernel after resume, and a set of address/value
pairs. This structure is used by the bootloader to restore a certain
number of registers (according to the set of address/value pairs) and
then jump back into the kernel at the provided location.
The code also puts the SDRAM into self-refresh mode, before calling
into board-specific code to actually enter the suspend to RAM state.

in include/linux/omap-gpmc.h. This will all become private data
to the GPMC driver once the legacy booting support can be dropped.

Pull "ARM: BCM5301X: Add some more devices to device tree" from Hauke Mehrtens:
The most important part is adding the axi bus to the SoC dtsi file,
this is the main bus on the SoC.
These patches were all send to the arm list and I haven't got any
negative responses.

The Cortex-A5x TRM states in paragraph "9.2 Generic Timer functional
description" that generic timers provide an active-LOW interrupt
output. Fix the device trees to correctly describe this.
While doing this update the CPU mask to match the number of described
CPUs as well.

Pull ARM SoC fixes from Arnd Bergmann:
"Not much interesting going on fixes-wise for us this week, as it
should be for an -rc7. I'm not expecting Olof to work much over
Thanksgiving weekend, so I decided to take over again and push these
out to you.
Just four simple fixes this week:
- one missing of_node_put() on armv7 based mvebu
- forcing the USB host into the right mode on Chromebook
(exynos5-snow)
- enabling two important drivers for exynos_defconfig
- fixing a noncritical bug for tegra that would cause a regression
with common code patches queued for 3.19"
* tag 'armsoc-for-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
ARM: tegra: irq: fix buggy usage of irq_data irq field
ARM: exynos_defconfig: Enable max77802 rtc and clock drivers
ARM: dts: Explicitly set dr_mode on exynos5250-snow
ARM: mvebu: add missing of_node_put() call in coherency.c

Pull ARM fixes from Russell King:
"Another round of relatively small ARM fixes.
Thomas spotted that the strex backoff delay bit was a disable bit, so
it needed to be clear for this to work. Vladimir spotted that using a
restart block for the cache flush operation would return -EINTR, which
userspace was not expecting. Dmitry spotted that the auxiliary
control register accesses for Xscale were not correct"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8226/1: cacheflush: get rid of restarting block
ARM: 8222/1: mvebu: enable strex backoff delay
ARM: 8216/1: xscale: correct auxiliary register in suspend/resume
