2017-03-16cpufreq: dbx500: Manage cooling device from cpufreq driverViresh Kumar
The best place to register the CPU cooling device is from the cpufreq driver as we would know if all the resources are already available or not. That's what is done for the cpufreq-dt.c driver as well. The cpu-cooling driver for dbx500 platform was just (un)registering with the thermal framework and that can be handled easily by the cpufreq driver as well and in proper sequence as well. Get rid of the cooling driver and its its users and manage everything from the cpufreq driver instead.

2017-03-15ARM: brcmstb: Enable ARCH_HAS_HOLES_MEMORYMODELDanesh Petigara
Due to the brcmstb SoC's memory map, we may have holes in the memory if we don't populate the maximum amount of memory supported by e.g: the first memory controller which spans either the first 1GiB or first 2GiB of memory. We need to select ARCH_HAS_HOLES_MEMORYMODEL in order to enable CONFIG_HAVE_ARCH_PFN_VALID on platforms that have CONFIG_SPARSEMEM enabled.

2017-03-15ARM: brcmstb: Enable ZONE_DMA for non 64-bit capable peripheralsAl Cooper
Some Host Controller hardware blocks, like the OHCI, EHCI and SDIO controllers, have hardware blocks that are not capable of doing 64 bit DMA. These host controllers fail on boards with >3GB of memory because the memory above 3GB is located physically >= 0x100000000 and can only be accessed using 64 DMA. The way Linux is currently configured for BRCMSTB systems, the memory given to drivers for DMA through functions like dma_alloc_coherent() comes from CMA memory and CMA memory is taken from the top of physical memory. When these drivers get a DMA buffer with an address >=0x100000000, they end up dropping the upper 32 bit of the address causing the hardware to DMA to incorrect memory, typically BMEM (custom memory carveout). This issue was discovered on a BCM97449SSV_DDR4 system with 4GB or memory. The fix is to enable CONFIG_ZONE_DMA. On ARM systems this makes sure that all DMA memory is located within the first 32 bits of address space.

The previously submitted patch did not resolve the random segmentation faults observed on the phantom buildd system. There are still unresolved problems with the Debian 4.8 and 4.9 kernels on C8000. The attached patch removes the flush of the offset map pages and does a whole data cache flush for large ranges. No other arch flushes the offset map in these routines as far as I can tell.

The parisc kernel doesn't work with CONFIG_MODVERSIONS since the commit 71810db27c1c853b335675bee335d893bc3d324b. It can't load modules with the error: "module unix: Unknown relocation: 41". The commit changes __kcrctab from 64-bit valus to 32-bit values. The assembler generates R_PARISC_SECREL32 secrel relocation for them and the module loader doesn't support this relocation.

The Amlogic P212 reference design is used by other devices as well, such as (for example) the Khadas VIM boards. Thus this patch adds and moves all common entries from meson-gxl-s905x-p212.dts to a new, separate meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the Khadas VIM). Support for all boards based on the P212 reference design includes: - enabling IR support - enabling the SAR ADC (SARADC_CH1 is connected to a resistor which indicates the hardware revision, a similar design is found on the Khadas VIM boards) - all MMC controllers (which means that SDIO wifi, the SD card and the eMMC are now supported) - pwm_ef as dependency for the SDIO wifi modules - uart_A which is connected to the bluetooth module (the bluetooth module itself is not enabled yet due to missing devicetree bindings for the Broadcom serial bluetooth devices) - uart_AO is moved to the .dtsi (as all known devices use it as their boot-console) Specific to the P212 board: - this also enables the CVBS connector (which is not available on the Khadas VIM boards for example) - Realtek based SDIO wifi (instead of Broadcom which most other devices use) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Tested-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2017-03-14x86/intel_rdt: Put group node in rdtgroup_kn_unlockJiri Olsa
The rdtgroup_kn_unlock waits for the last user to release and put its node. But it's calling kernfs_put on the node which calls the rdtgroup_kn_unlock, which might not be the group's directory node, but another group's file node. This race could be easily reproduced by running 2 instances of following script: mount -t resctrl resctrl /sys/fs/resctrl/ pushd /sys/fs/resctrl/ mkdir krava echo "krava" > krava/schemata rmdir krava popd umount /sys/fs/resctrl It triggers the slub debug error message with following command line config: slub_debug=,kernfs_node_cache.

2017-03-14x86/unwind: Fix last frame check for aligned function stacksJosh Poimboeuf
Pavel Machek reported the following warning on x86-32: WARNING: kernel stack frame pointer at f50cdf98 in swapper/2:0 has bad value (null) The warning is caused by the unwinder not realizing that it reached the end of the stack, due to an unusual prologue which gcc sometimes generates for aligned stacks. The prologue is based on a gcc feature called the Dynamic Realign Argument Pointer (DRAP). It's almost always enabled for aligned stacks when -maccumulate-outgoing-args isn't set. This issue is similar to the one fixed by the following commit: 8023e0e2a48d ("x86/unwind: Adjust last frame check for aligned function stacks") ... but that fix was specific to x86-64. Make the fix more generic to cover x86-32 as well, and also ensure that the return address referred to by the frame pointer is a copy of the original return address.

We want to be able to dynamically allocate struct omap_hwmod_ocp_if and struct omap_hwmod at device driver probe time based on .dts data. Current setup with the linkspace using memblock_virt_alloc() makes this tricky, so let's get rid of struct linkspace and directly set up struct omap_hwmod_ocp_if as the master and slave lists. As we are currently not using the master_ports either, let's remove it too. And let's add the struct omap_hwmod_ocp_if node directly to the slave_ports list.

2017-03-14x86/hugetlb: Adjust to the new native/compat mmap basesDmitry Safonov
Commit 1b028f784e8c introduced two mmap() bases for 32-bit syscalls and for 64-bit syscalls. The mmap() code in x86 was modified to handle the separation, but the patch series missed to update the hugetlb code. As a consequence a 32bit application mapping a file on hugetlbfs uses the 64-bit mmap base for address space allocation, which fails. Adjust the hugetlb mapping code to use the proper bases depending on the syscall invocation mode (64-bit or compat).

2017-03-14ARM: at91: pm: cpu_idle: switch DDR to power-down modeNicolas Ferre
On some DDR controllers, compatible with the sama5d3 one, the sequence to enter/exit/re-enter the self-refresh mode adds more constrains than what is currently written in the at91_idle driver. An actual access to the DDR chip is needed between exit and re-enter of this mode which is somehow difficult to implement. This sequence can completely hang the SoC. It is particularly experienced on parts which embed a L2 cache if the code run between IDLE calls fits in it... Moreover, as the intention is to enter and exit pretty rapidly from IDLE, the power-down mode is a good candidate. So now we use power-down instead of self-refresh. As we can simplify the code for sama5d3 compatible DDR controllers, we instantiate a new sama5d3_ddr_standby() function.

2017-03-14x86/kasan: Fix boot with KASAN=y and PROFILE_ANNOTATED_BRANCHES=yAndrey Ryabinin
The kernel doesn't boot with both PROFILE_ANNOTATED_BRANCHES=y and KASAN=y options selected. With branch profiling enabled we end up calling ftrace_likely_update() before kasan_early_init(). ftrace_likely_update() is built with KASAN instrumentation, so calling it before kasan has been initialized leads to crash. Use DISABLE_BRANCH_PROFILING define to make sure that we don't call ftrace_likely_update() from early code before kasan_early_init().

2017-03-13x86/platform: Remove warning message for duplicate NMI handlersMike Travis
Remove the WARNING message associated with multiple NMI handlers as there are at least two that are legitimate. These are the KGDB and the UV handlers and both want to be called if the NMI has not been claimed by any other NMI handler. Use of the UNKNOWN NMI call chain dramatically lowers the NMI call rate when high frequency NMI tools are in use, notably the perf tools. It is required on systems that cannot sustain a high NMI call rate without adversely affecting the system operation.
