Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") changed many more clocks than only the SPDIF core clock as stated in the commit message. The MLB clock has been added and this causes SPDIF regression as reported by Xavi Drudis Ferran and also in this forum post: https://forum.digikey.com/thread/34240 The MX6Q Reference Manual does not mention that MLB is a clock related to SPDIF, so change it back to a dummy clock to restore SPDIF functionality.

2016-08-25ARM: tegra: Correct polarity for Tegra114 PMIC interruptJon Hunter3-3/+3
The ARM GIC only supports interrupts with either level-high or rising-edge types for SPIs. The interrupt type for the Palmas PMIC used for Tegra114 boards is specified as level-low which is invalid for the GIC. This has gone undetected because until recently, failures to set the interrupt type when the interrupts are mapped via firmware (such as device-tree) have not been reported. Since commits 4b357daed698 ("genirq: Look-up trigger type if not specified by caller") and 1e2a7d78499e ("irqdomain: Don't set type when mapping an IRQ"), failure to set the interrupt type will cause the requesting of the interrupt to fail and exposing incorrectly configured interrupts. Please note that although the interrupt type was never being set for the Palmas PMIC, it was still working fine, because the default type setting for the interrupt, 'level-high', happen to match the correct type for the interrupt. Finally, it should be noted that the Palmas interrupt from the PMIC is actually 'level-low', however, this interrupt signal is inverted by the Tegra PMC and so the GIC actually sees a 'level-high' interrupt which is what should be specified in the device-tree interrupt specifier.

2016-08-20parisc: Fix order of EREFUSED define in errno.hHelge Deller1-2/+2
When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

2016-08-18x86/smp: Fix __max_logical_packages value setupJiri Olsa1-9/+16
Frank reported kernel panic when he disabled several cores in BIOS via following option: Core Disable Bitmap(Hex) [0] with number 0xFFE, which leaves 16 CPUs in system (out of 48). The kernel panic below goes along with following messages: smpboot: Max logical packages: 2^M smpboot: APIC(0) Converting physical 0 to logical package 0^M smpboot: APIC(20) Converting physical 1 to logical package 1^M smpboot: APIC(40) Package 2 exceeds logical package map^M smpboot: CPU 8 APICId 40 disabled^M smpboot: APIC(60) Package 3 exceeds logical package map^M smpboot: CPU 12 APICId 60 disabled^M ... general protection fault: 0000 [#1] SMP^M Modules linked in:^M CPU: 15 PID: 1 Comm: swapper/0 Not tainted 4.7.0-rc5+ #1^M Hardware name: SGI UV300/UV300, BIOS SGI UV 300 series BIOS 05/25/2016^M task: ffff8801673e0000 ti: ffff8801673ac000 task.ti: ffff8801673ac000^M RIP: 0010:[<ffffffff81014d54>] [<ffffffff81014d54>] uncore_change_context+0xd4/0x180^M ...

The __max_logical_packages is computed as: DIV_ROUND_UP(total_cpus, ncpus); - ncpus being number of cores With above BIOS setup we get total_cpus == 16 which set __max_logical_packages to 2 (ncpus is 12). Once topology_update_package_map processes CPU with logical pkg over 2 we display above messages and fail to initialize the physical_to_logical_pkg map, which makes the uncore code crash. The fix is to remove logical_package_map bitmap completely and keep and update the logical_packages number instead. After we enumerate all the present CPUs, we check if the enumerated logical packages count is within its computed maximum from BIOS data. If it's not the case, we set this maximum to the new enumerated value and freeze any new addition of logical packages. The freeze is because lot of init code like uncore/rapl/cqm depends on having maximum logical package value set to allocate their data, so we can't change it later on.

Literal loads of virtual addresses are subject to runtime relocation when CONFIG_RELOCATABLE=y, and given that the relocation routines run with the MMU and caches enabled, literal loads of relocated values performed with the MMU off are not guaranteed to return the latest value unless the memory covering the literal is cleaned to the PoC explicitly. So defer the literal load until after the MMU has been enabled, just like we do for primary_switch() and secondary_switch() in head.S.

2016-08-17ARM: imx6ul: populates platform device at .init_machinePeter Chen1-0/+1
At imx6ul_init_machine, it calls imx6ul_pm_init which needs to find platform device for ocram, but the default populate platform device is at of_platform_default_populate_init, which is located at arch_initcall_sync, and called later than arch_initcall (.init_machine is located at that). So below warning message will be showed during boots up: imx6q_suspend_init: failed to find ocram device! imx6_pm_common_init: No DDR LPM support with suspend -19! Due to lack of ocram device, the suspend mode "mem" which needs ocram to store suspend routine code is invalid. This commit populates platform device before imx6ul_pm_init like other imx6 platforms do, and the suspend mode "mem" can work successfully.

This fix was applied to a bunch of omap3 devices including LogicPD Torpedo, but this got missed since it was new around the same times the patches were applied.

The gpmc ranges property for NAND at CS0 was being overridden by later includes that defined gpmc ethernet nodes, effectively breaking NAND on these systems: omap-gpmc 6e000000.gpmc: /ocp/gpmc@6e000000/nand@0,0 has malformed 'reg' property Instead of redefining the NAND range in every such dtsi, define all currently used ranges in omap3-overo-base.dtsi.

This currently prevents the nand gpmc child node from being probed: omap-gpmc 6e000000.gpmc: /ocp/gpmc@6e000000/nand@0,0 has malformed 'reg' property and consequently the NAND device from being registered.
