2014-06-17ARM: integrator: fix section mismatch problemLinus Walleij
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.

2014-06-17ARM: mvebu: DT: fix OpenBlocks AX3-4 RAM sizeJason Cooper
The OpenBlocks AX3-4 has a non-DT bootloader. It also comes with 1GB of soldered on RAM, and a DIMM slot for expansion.

2014-06-17ARM: samsung: make SAMSUNG_DMADEV optionalArnd Bergmann
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.

2014-06-17remoteproc: da8xx: don't select CMA on no-MMUArnd Bergmann
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.

2014-06-17bus/arm-cci: add dependency on OF && CPU_V7Arnd Bergmann
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.

2014-06-17ARM: keystone requires ARM_PATCH_PHYS_VIRTArnd Bergmann
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.

2014-06-17ARM: omap2: fix am43xx dependency on l2x0 cacheArnd Bergmann
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.

It got a bit delayed in part because I wasn't paying attention, and in part because I discovered I had a core PCI change without a PCI maintainer ack in it. Bjorn eventually agreed it was ok to merge it though we'll probably improve it later and I didn't want to rebase to add his ack. There is going to be a bit more next week, essentially fixes that I still want to sort through and test. The biggest item this time is the support to build the ppc64 LE kernel with our new v2 ABI. We previously supported v2 userspace but the kernel itself was a tougher nut to crack. This is now sorted mostly thanks to Anton and Rusty. We also have a fairly big series from Cedric that add support for 64-bit LE zImage boot wrapper. This was made harder by the fact that traditionally our zImage wrapper was always 32-bit, but our new LE toolchains don't really support 32-bit anymore (it's somewhat there but not really "supported") so we didn't want to rely on it. This meant more churn that just endian fixes. This brings some more LE bits as well, such as the ability to run in LE mode without a hypervisor (ie. under OPAL firmware) by doing the right OPAL call to reinitialize the CPU to take HV interrupts in the right mode and the usual pile of endian fixes. There's another series from Gavin adding EEH improvements (one day we *will* have a release with less than 20 EEH patches, I promise!). Another highlight is the support for the "Split core" functionality on P8 by Michael. This allows a P8 core to be split into "sub cores" of 4 threads which allows the subcores to run different guests under KVM (the HW still doesn't support a partition per thread).

Using that, we can target a fairly narrow group of systems. i.e. old enough to not have HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9. This group may be further limited if some systems respond with something other than 4 to non-existant feature queries.

2014-06-10thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540Hans de Goede
The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12 keys should be mapped to: control-panel, search, show-all-windows and Computer. These keys generate the sofar unused 28 - 31 hotkey scancodes. For the first 2 this nicely matches the icons on the keys, for the latter 2 the icons are somewhat creative, which is why I ended up looking them up in the user manual.

2014-06-10decode_stacktrace: make stack dump output useful againSasha Levin
Right now when people try to report issues in the kernel they send stack dumps to eachother, which looks something like this: [ 6.906437] [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20 [ 6.907121] [<ffffffff84388ce8>] dump_stack+0x52/0x7f [ 6.907640] [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110 [ 6.908281] [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0 [ 6.908870] [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22 [ 6.909480] [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0 [...] However, most of the text you get is pure garbage. The only useful thing above is the function name. Due to the amount of different kernel code versions and various configurations being used, the kernel address and the offset into the function are not really helpful in determining where the problem actually occured. Too often the result of someone looking at a stack dump is asking the person who sent it for a translation for one or more 'addr2line' translations. Which slows down the entire process of debugging the issue (and really annoying). The decode_stacktrace script is an attempt to make the output more useful and easy to work with by translating all kernel addresses in the stack dump into line numbers. Which means that the stack dump would look like this: [ 635.148361] dump_stack (lib/dump_stack.c:52) [ 635.149127] warn_slowpath_common (kernel/panic.c:418) [ 635.150214] warn_slowpath_null (kernel/panic.c:453) [ 635.151031] _oalloc_pages_slowpath+0x6a/0x7d0 [ 635.152171] ? zone_watermark_ok (mm/page_alloc.c:1728) [ 635.152988] ? get_page_from_freelist (mm/page_alloc.c:1939) [ 635.154766] __alloc_pages_nodemask (mm/page_alloc.c:2766) It's pretty obvious why this is better than the previous stack dump before. Usage is pretty simple: ./decode_stacktrace.sh [vmlinux] [base path] Where vmlinux is the vmlinux to extract line numbers from and base path is the path that points to the root of the build tree, for example: ./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log The stack trace should be piped through it (I, for example, just pipe the output of the serial console of my KVM test box through it).

All three iop variants we support in Linux (iop32x, iop33x and iop13xx) seem to have support for the watchdog hardware, but this driver fails to build for the first two of these because it uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for iop13xx. This clarifies the dependency in Kconfig to avoid randconfig build errors.
