24bbd929e6 of/fdt: split off FDT self reservation from memreserve processing
This splits off the reservation of the memory occupied by the FDT
binary itself from the processing of the memory reservations it
contains. This is necessary because the physical address of the FDT,
which is needed to perform the reservation, may not be known to the
FDT driver core, i.e., it may be mapped outside the linear direct
mapping, in which case __pa() returns a bogus value.

iwlwifi/Kconfig and mac80211.h were both trivial overlapping
changes.

The drivers/net/phy/amd-xgbe-phy.c file got removed in 'net-next' and
the bug fix that happened on the 'net' side is already integrated
into the rest of the amd-xgbe driver.

7a6cb0abe1 ARM: dts: am335x-boneblack: disable RTC-only sleep to avoid hardware damage
Avoid entering "RTC-only mode" at poweroff. It is unsupported by most
versions of BeagleBone, and risks hardware damage.

The damaging configuration is having system-power-controller

b33558c906 ARM: dts: AM35xx: fix system control module clocks
New system control module layout for omap3 overlooked parts of the am35xx
configuration. Basically the am35xx clocks were not converted to use the
changed offsets, which caused weird boot warnings. The errors were not
fatal so far, so they were not caught earlier. Fixed by applying the
proper offsets for the AM35xx scm clocks.

1a02b6627b Fix for Exynos3250 RTC wake-up interrupts after converting PMU
wakeup to stacked domains. This allows waking up the device from
 suspend to RAM using S3C RTC driver (the RTC on SoC).
 
 The patch should be applied some time ago, unfortunately
 it seems it slipped through fingers.

fe931229c6 ARM: exynos: Fix wake-up interrupts for Exynos3250
Commit 8b283c0254 (ARM: exynos4/5: convert pmu wakeup to
stacked domains) changed the Exynos PMU code to use stacked
domains. This has led to a number of interrupt numbers to be
fixed.

In the meantime, support for Exynos 3250 was added, missing
the required change to this platform. This amounts to revert
ace283a04a (ARM: EXYNOS: Fix wrong hwirq of RTC interrupt
for Exynos3250 SoC), as the initial patch was right, just a
bit early...

7bbfbb9866 The i.MX fixes for 4.1, 3rd round:
It includes a couple of fixes for i.MX6 GPC code to let the new kernel
 be able to boot with old DTBs:
 
  - Booting v4.1-rc kernel with old DTBs will fail with a fat warning
    (require low-level debug to be seen), due to the adoption of stacked
    IRQ domain.  The first fix improves the situation by allowing kernel
    boot up with old DTBs, although suspend/resume still breaks.
 
  - Booting new kernel with old DTBs that do not have power-domain info
    will result in a hang.  The second patch fixes the hang by skipping
    the kernel power-domain registration if DTB has no power-domain info.

[<c06b9a47>] (start_kernel) from [<8000807f>] (0x8000807f)

The power management related assembly on omaps needs to interact with
ARM mode bootrom code, so we need to keep most of the related assembly
in ARM mode.

Turns out this error is because of missing ENDPROC for assembly code
as suggested by Stephen Boyd <sboyd@codeaurora.org>. Let's fix the
problem by adding ENDPROC in two places to sleep34xx.S.

Let's also remove the now duplicate custom code for mode switching.
This has been unnecessary since commit 6ebbf2ce43 ("ARM: convert
all "mov.* pc, reg" to "bx reg" for ARMv6+").

And let's also remove the comments about local variables, they are
now just confusing after the ENDPROC.

The reason why ENDPROC makes a difference is it sets .type and then
the compiler knows what to do with the thumb bit as explained at:

b01aec9b2c EDAC: Cleanup atomic_scrub mess
So first of all, this atomic_scrub() function's naming is bad. It looks
like an atomic_t helper. Change it to edac_atomic_scrub().

The bigger problem is that this function is arch-specific and every new
arch which doesn't necessarily need that functionality still needs to
define it, otherwise EDAC doesn't compile.

So instead of doing that and including arch-specific headers, have each
arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c
for ifdeffery. Much cleaner.

And we already are doing this with another symbol - EDAC_SUPPORT. This
is also much cleaner than having CONFIG_EDAC enumerate all the arches
which need/have EDAC support and drivers.

This way I can kill the useless edac.h header in tile too.

kvm_memslots and id_to_memslot.  It will simplify the code when more
than one address space will be supported.

Unfortunately, the "const"ness of the new argument must be casted
away in two places.  Fixing KVM to accept const struct kvm_memory_slot
pointers would require modifications in pretty much all architectures,
and is left for later.

We make use of the PSCI function IDs, but don't explicitly include the

b17c70cd92 ARM: imx6: gpc: don't register power domain if DT data is missing
If the devicetree is too old and does not provide the regulator and clocks
for the power domain, we need to avoid registering the power domain.
Otherwise runtime PM will try to control the domain, which will lead to
machine hangs without the proper DT configuration data.

This restores functionality to the kernel 4.0 level if an old DT is
detected, where the power domain is constantly powered on.

634a603760 ARM: imx6: allow booting with old DT
The GPC rewrite to IRQ domains has been on the premise that it may break
suspend/resume for new kernels on old DT, but otherwise keep things working
from a user perspective. This was an accepted compromise to be able to move
the GIC cleanup forward.

What actually happened was that booting a new kernel on an old DT crashes
before even the console is up, so the user does not even see the warning
that the DT is too old. The warning message suggests that this has been
known before, which is clearly unacceptable.

Fix the early crash by mapping the GPC memory space if the IRQ controller
doesn't claim it. This keeps at least CPUidle and the needed CPU wakeup
workarounds working. With this fixed the system is able to boot up
properly minus the expected suspend/resume breakage.

f25bf74c88 ARM: dts: Fix WLAN interrupt line for AM335x EVM-SK
While Sitara AM335x SoCs are very close to OMAP SoCs, the 32-line GPIO
controllers are numbered from 0 on AM335x and from 1 on OMAP. But when
the configuration for the TI WLAN controllers was converted from
platform data to device tree, this detail was overlooked, as 10 boards
were using OMAP with the WL12xx and WL18xx controllers, and only one
was based on AM335x.

This invalid configuration prevents the WL1271 module on the AM335x
EVM-SK from notifying interrupts to the SoC, and breaks the wlan driver.

The DTS must be corrected to use the correct GPIO controller.

The !CONFIG_SMP implementation of futex_atomic_op_inuser() seems to rely
on disabled preemption to guarantee mutual exclusion.

From commit e589ed23dd ("[ARM] 5218/1: arm: improved futex support"):

    "For UP it's enough to disable preemption to ensure mutual exclusion..."

From the code itself:

    "!SMP, we can work around lack of atomic ops by disabling preemption"

Let's make this explicit, to prepare for pagefault_disable() not
touching preemption anymore.

70ffdb9393 mm/fault, arch: Use pagefault_disable() to check for disabled pagefaults in the handler
Introduce faulthandler_disabled() and use it to check for irq context and
disabled pagefaults (via pagefault_disable()) in the pagefault handlers.

Please note that we keep the in_atomic() checks in place - to detect
whether in irq context (in which case preemption is always properly
disabled).

In contrast, preempt_disable() should never be used to disable pagefaults.
With !CONFIG_PREEMPT_COUNT, preempt_disable() doesn't modify the preempt
counter, and therefore the result of in_atomic() differs.
We validate that condition by using might_fault() checks when calling
might_sleep().

Therefore, add a comment to faulthandler_disabled(), describing why this
is needed.

faulthandler_disabled() and pagefault_disable() are defined in
linux/uaccess.h, so let's properly add that include to all relevant files.

This patch is based on a patch from Thomas Gleixner.

2cb7c9cb42 sched/preempt, mm/kmap: Explicitly disable/enable preemption in kmap_atomic_*
The existing code relies on pagefault_disable() implicitly disabling
preemption, so that no schedule will happen between kmap_atomic() and
kunmap_atomic().

Let's make this explicit, to prepare for pagefault_disable() not
touching preemption anymore.

Commit 338d9dd3e2 ("ARM: 8351/1: perf: don't warn about missing
interrupt-affinity property for PPIs") added a check for PPIs so that
we avoid parsing the interrupt-affinity property for these naturally
affine interrupts.

Unfortunately, this check can trigger an early (successful) return and
we will leak the irqs array. This patch fixes the issue by reordering
the code so that the check is performed before any independent
allocation.

1b97937246 ARM: fix missing syscall trace exit
Josh Stone reports:

  I've discovered a case where both arm and arm64 will miss a ptrace
  syscall-exit that they should report.  If the syscall is entered
  without TIF_SYSCALL_TRACE set, then it goes on the fast path.  It's
  then possible to have TIF_SYSCALL_TRACE added in the middle of the
  syscall, but ret_fast_syscall doesn't check this flag again.

Fix this by always checking for a syscall trace in the fast exit path.

965278dcb8 ARM: 8356/1: mm: handle non-pmd-aligned end of RAM
At boot time we round the memblock limit down to section size in an
attempt to ensure that we will have mapped this RAM with section
mappings prior to allocating from it. When mapping RAM we iterate over
PMD-sized chunks, creating these section mappings.

Section mappings are only created when the end of a chunk is aligned to
section size. Unfortunately, with classic page tables (where PMD_SIZE is
2 * SECTION_SIZE) this means that if a chunk is between 1M and 2M in
size the first 1M will not be mapped despite having been accounted for
in the memblock limit. This has been observed to result in page tables
being allocated from unmapped memory, causing boot-time hangs.

This patch modifies the memblock limit rounding to always round down to
PMD_SIZE instead of SECTION_SIZE. For classic MMU this means that we
will round the memblock limit down to a 2M boundary, matching the limits
on section mappings, and preventing allocations from unmapped memory.
For LPAE there should be no change as PMD_SIZE == SECTION_SIZE.

6f024978e7 ARM: EXYNOS: Fix failed second suspend on Exynos4
On Exynos4412 boards (Trats2, Odroid U3) after enabling L2 cache in
56b60b8bce ("ARM: 8265/1: dts: exynos4: Add nodes for L2 cache
controller") the second suspend to RAM failed. First suspend worked fine
but the next one hang just after powering down of secondary CPUs (system
consumed energy as it would be running but was not responsive).

The issue was caused by enabling delayed reset assertion for CPU0 just
after issuing power down of cores. This was introduced for Exynos4 in
13cfa6c4f7 ("ARM: EXYNOS: Fix CPU idle clock down after CPU off").

The whole behavior is not well documented but after checking with vendor
code this should be done like this (on Exynos4):
1. Enable delayed reset assertion when system is running (for all CPUs).
2. Disable delayed reset assertion before suspending the system.
   This can be done after powering off secondary CPUs.
3. Re-enable the delayed reset assertion when system is resumed.

Four minor merge conflicts:

1) qca_spi.c renamed the local variable used for the SPI device
   from spi_device to spi, meanwhile the spi_set_drvdata() call
   got moved further up in the probe function.

2) Two changes were both adding new members to codel params
   structure, and thus we had overlapping changes to the
   initializer function.

3) 'net' was making a fix to sk_release_kernel() which is
   completely removed in 'net-next'.

4) In net_namespace.c, the rtnl_net_fill() call for GET operations
   had the command value fixed, meanwhile 'net-next' adjusted the
   argument signature a bit.

This also matches example merge resolutions posted by Stephen
Rothwell over the past two days.

0b7dc0ff95 ARM: EXYNOS: Fix dereference of ERR_PTR returned by of_genpd_get_from_provider
ERR_PTR was dereferenced during sub domain parsing, if parent domain
could not be obtained (because of invalid phandle or deferred
registration of parent domain).

The Exynos power domain code checked whether
of_genpd_get_from_provider() returned NULL and in that case it skipped
that power domain node. However this function returns ERR_PTR or valid

This is happening because pmu_base_addr is only initialized when the
PMU is an interrupt controller. It's not the case on old DT.

b270687977 ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for Peach Boards
The Marvell mwifiex driver prevents the system to enter into a suspend
state if the card power is not preserved during a suspend/resume cycle.

So Suspend-to-RAM and Suspend-to-idle is failing on Exynos5800 Peach Pi
and Exynos5420 Peach Pit Chromebooks.

Add the keep-power-in-suspend Power Management property to the SDIO/MMC
node so the mwifiex suspend handler doesn't fail and the system is able
to enter into a suspend state.

Merge tag 'for-v4.1-rc/omap-fixes-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.1/fixes

ARM: OMAP2+: first set of hwmod fixes for v4.1-rc

Fix a few AM43xx problems: add the VPFE hwmod data, which removes some
warnings; and fix the IP block hardreset implementation.

Basic build, boot, and PM test results are here:

http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.1-rc/20150508130543/

Note that I do not have an AM43xx board in the testbed, and thus
cannot test on that platform.

b0897972ed ARM: OMAP2+: Remove bogus struct clk comparison for timer clock
With recent changes to use determine_rate, the comparison of two
clocks won't work without clk_is_match that does __clk_get_hw
on the clocks first.

As we've been unconditionally already calling clk_set_parent
already because of the bogus comparison, let's just remove the
check as suggested by Stephen Boyd <sboyd@codeaurora.org>.

6499e8cfaa crypto: arm/aes - streamline AES-192 code path
This trims off a couple of instructions of the total size of the
core AES transform by reordering the final branch in the AES-192
code path with the rounds that are performed regardless of whether
the branch is taken or not. Other than the slight size reduction,
this has no performance benefit.

c80ae7ca37 crypto: arm/sha512 - accelerated SHA-512 using ARM generic ASM and NEON
This replaces the SHA-512 NEON module with the faster and more
versatile implementation from the OpenSSL project. It consists
of both a NEON and a generic ASM version of the core SHA-512
transform, where the NEON version reverts to the ASM version
when invoked in non-process context.

This patch is based on the OpenSSL upstream version b1a5d1c65208
of sha512-armv4.pl, which can be found here:

  https://git.openssl.org/gitweb/?p=openssl.git;h=b1a5d1c65208

Performance relative to the generic implementation (measured
using tcrypt.ko mode=306 sec=1 running on a Cortex-A57 under
KVM):

0b59d8806a ARM: net: delegate filter to kernel interpreter when imm_offset() return value can't fit into 12bits.
The ARM JIT code emits "ldr rX, [pc, #offset]" to access the literal
pool. #offset maximum value is 4095 and if the generated code is too
large, the #offset value can overflow and not point to the expected
slot in the literal pool. Additionally, when overflow occurs, bits of
the overflow can end up changing the destination register of the ldr
instruction.

Fix that by detecting the overflow in imm_offset() and setting a flag
that is checked for each BPF instructions converted in
build_body(). As of now it can only be detected in the second pass. As
a result the second build_body() call can now fail, so add the
corresponding cleanup code in that case.

Using multiple literal pools in the JITed code is going to require
lots of intrusive changes to the JIT code (which would better be done
as a feature instead of fix), just delegating to the kernel BPF
interpreter in that case is a more straight forward, minimal fix and
easy to backport.

Commit ea08de16eb ("ARM: dts: Add DISP1 power domain for exynos5420")
added a device node for the Exynos5420 DISP1 power domain but dit not
make the DP controller a consumer of that power domain.

This causes an "Unhandled fault: imprecise external abort" error if the
exynos-dp driver tries to access the DP controller registers and the PD
was turned off. This lead to a kernel panic and a complete system hang.

Make the DP controller device node a consumer of the DISP1 power domain
to ensure that the PD is turned on when the exynos-dp driver is probed.
