Hi Everyone,

here are the fixes I've picked up so far as the last pull request
for the merge window. I'm sure there will be a lot more in the
future, but let us know if I missed something or if any of the
patches (in particular mine, some of which I have not posted
before) are not ok.

* [PATCH 01/14] ARM: mvebu: fix randconfig builds for pmsu driver

local_flush_tlb_all() is not available for NOMMU NOSMP builds.
The isb() assembly instruction is not available when building
a combined ARMv6/v7 kernel, unlike the isb() inline that falls
back to the ARMv6 opcode.
If CPUIDLE support is disabled globally, we must not call
arm_cpu_suspend. If it is enabled, we should ensure that it
is available.

* [PATCH 02/14] ARM: omap2: fix am43xx dependency on l2x0 cache
  2014-06-13 16:01 ` Arnd Bergmann

  -1 siblings, 0 replies; 30+ messages in thread
From: Arnd Bergmann @ 2014-06-13 16:01 UTC (permalink / raw)
  To: linux-arm-kernel; +Cc: arm, Arnd Bergmann, linux-omap, Tony Lindgren

Commit d941f86fad41b ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:

arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'

This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.

This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.

The dynamic relocation that the keystone platform performs
only works if we can pick the phys offset at boot time. It's
possible that there is another solution for this, but this
is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT
are not portable across platforms, and I see no reason why
anyone would run a kernel without ARM_PATCH_PHYS_VIRT on
keystone.

The arm-cci code uses device tree helpers for initialization
that don't work on kernels built without CONFIG_OF. Further,
it contains an inline assembly in cci_enable_port_for_self()
that uses ARMv7 instructions and fails to build when targetting
other ARM instruction set versions.

This works around both issues by limiting the scope of the
Kconfig symbol to platforms that can actually build this driver
cleanly.

We can only use CMA on systems that have an MMU, because of
the requirement to use memory migration. NOMMU systems are
rather constrained to start with, but it seems reasonable
to assume that DMA allocations can still succeed in the
constrained case for remoteproc on NOMMU, so this patch
changes the da8xx implementation to not rely on CMA when
the MMU is disabled.

* [PATCH 06/14] ARM: samsung: make SAMSUNG_DMADEV optional

The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.

This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.

In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

The OpenBlocks AX3-4 has a non-DT bootloader.  It also comes with 1GB of
soldered on RAM, and a DIMM slot for expansion.

Unfortunately, atags_to_fdt() doesn't work in big-endian mode, so we see
the following failure when attempting to boot a big-endian kernel:

A similar failure will also occur if ARM_ATAG_DTB_COMPAT isn't selected.

Fix this by setting a sane default (1 GB) in the dts file.

From: Linus Walleij <linus.walleij@linaro.org>

This addresses a section mismatch problem in the IM-PD1
driver in the Integrator/AP.

The IM-PD1 contains a VIC interrupt controller and therefore
the driver calls vic_init_cascaded() which is marked __init as
irqchips are simply not hot-pluggable and specifically the VIC
is assumed to initiate only on boot.

However the module driver model of the Integrator LM bus
assumes that logic tile drivers can be probed at runtime. This
is not really the case for IM-PD1: these tiles are detected at
boot and they cannot be plugged into a running system. Before
this patch it is of course possible to modprobe them later.

By first forcing the IM-PD1 to bool we make sure this driver
gets compiled into the kernel, and we know it will be probed
only at boot time when the tiles are detected, so we can tag
its probe function __init_refok as we know it won't be called
after boot now, and the section mismatch problem goes away.

As a side effect, sysfs binding from userspace becomes
impossible, so we tag the driver to suppress the bind/unbind
sysfs attributes.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

From: Dan Carpenter <dan.carpenter@oracle.com>

This function should be returning an ERR_PTR() on failure instead of
NULL.  Also there is a use after free bug if regmap_init() fails because
we free "func" and then dereference doing the return.

* [PATCH 11/14] ARM: exynos: cleanup kconfig option display

	Arnd Bergmann

From: Rob Herring <robh@kernel.org>

The addition of Exynos to multi-platform configs creates a mess of config
options with options appearing before the Exynos config option. This is
due to arch/arm/plat-samsung/Kconfig being included out of order with the
other Samsung platform kconfig files. Reorder the kconfig files and move
all the options into a sub-menu. Some of the options are dead, so remove
those as well.

The System Type menu is getting quite long with platforms and is
inconsistent in handling of sub-arch specific options. Tidy up the menu
by making platform options a menuconfig entry containing any platform
specific config items.

  To: linux-arm-kernel

From: Olof Johansson <olof@lixom.net>

This solves a problem with building with CONFIG_SMP=n due to missing
sysram_base_addr (or sysram_ns_base_addr) variables.

The new setup method is more awkward than I'd like for it to be, but
it can't be done in init_early() since ioremap is not yet available,
but it needs to happen before SMP.

Dear Arnd Bergmann,

So noMMU builds are supported in a single image with MMU builds?
Instead of having to #ifdef all around the place, wouldn't it be better
for the noMMU headers to provide an empty definition for this function?

This unfortunately isn't really correct, and the patch I sent in
"[PATCH] ARM: mvebu: select ARM_CPU_SUSPEND for Marvell EBU v7
platforms" on June, 11th already fixes the cpu_suspend()/cpu_resume()
problem.

The issue with your solution is that it assumes this function is only
used for cpuidle. That is indeed the case in v3.16, but will be wrong
as soon as we add CPU hotplug support, which I have posted on May, 30th
in "[PATCH 0/5] CPU hotplug for Marvell Armada XP", and which I hope to
see included in v3.17.

Thanks!

Thomas

It's not supported yet, but I have a patch to do that, which I used for
testing this code. I try to have the platform code ready before submitting
the main patch.

Yes, good point, it should probably be part of the main patch then.

Right. I'll drop this patch from the submission then. You came just in
time, as I had originally planned to send it out this morning.

I'll also follow up with a separate patch to address the isb() issue.

Ok, thanks a lot!

So, should my patch adding the "select ARM_CPU_SUSPEND" be taken by
Jason and then pushed to you, or will you apply it directly?

Thanks!

I'll wait for Jason to pick it up. It was clearly a mistake for me
to include my own patch directly and without an explicit Ack, I'll go
back to the normal way of doing things ;-)

Why is this needed when multi-platform already selects this?

I have a patch to make ARM_PATCH_PHYS_VIRT optional for multi-platform,
which I plan to post at some point in the next weeks. This will let
us enable NOMMU builds and other things in platforms that are
converted to multiplatform (at the obvious expense of losing generality
for that particular build). Most other platforms can work with or without
ARM_PATCH_PHYS_VIRT, but keystone lost that ability.
