2017-06-05ARM: dts: imx: Fix Ethernet PHY reset polarityFabio Estevam32-31/+33
The FEC driver ignores the GPIO polarity from 'phy-reset-gpios' and considers that the Ethernet PHY is active low, unless the property 'phy-reset-active-high' is present. Fix the device tree description by explicitly passing the 'GPIO_ACTIVE_LOW' flag to the 'phy-reset-gpios' property.

2017-05-25ARM: dts: tx6: Remove 'enable-active-low' propertyFabio Estevam2-4/+2
Property 'enable-active-low' does not exist. Only 'enable-active-high' is valid, and when this property is absent the gpio regulator will act as active low by default. So remove the unexisting 'enable-active-low' property. Currently the GPIO flag is GPIO_ACTIVE_HIGH. In order to make the dts description accurate, pass the GPIO_ACTIVE_LOW flag instead. This change is safe because the gpio regulator driver does not take the GPIO flag polarity into account.

2017-05-25ARM: dts: imx: Add generic compatible string for I2C EEPROMJavier Martinez Canillas6-6/+6
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

The size regression is fixed by moving all dax helpers into the dax-core and only specifying "select DAX" for FS_DAX and dax-capable drivers. He also asked for clarification of the NR_DEV_DAX config option which, on closer look, does not need to be a config option at all. Mike also throws in a DEV_DAX_PMEM fixup for good measure. - Ben's attention to detail on -stable patch submissions caught a case where the recent fixes to arch_copy_from_iter_pmem() missed a condition where we strand dirty data in the cache. This is tagged for -stable and will also be included in the rework of the pmem api to a proposed {memcpy,copy_user}_flushcache() interface for 4.13. - Vishal adds a feature that missed the initial pull due to pending review feedback. It allows the kernel to clear media errors when initializing a BTT (atomic sector update driver) instance on a pmem namespace. - Ross noticed that the dax_device + dax_operations conversion broke __dax_zero_page_range().

2017-05-11xen: adjust early dom0 p2m handling to xen hypervisor behaviorJuergen Gross1-3/+4
When booted as pv-guest the p2m list presented by the Xen is already mapped to virtual addresses. In dom0 case the hypervisor might make use of 2M- or 1G-pages for this mapping. Unfortunately while being properly aligned in virtual and machine address space, those pages might not be aligned properly in guest physical address space. So when trying to obtain the guest physical address of such a page pud_pfn() and pmd_pfn() must be avoided as those will mask away guest physical address bits not being zero in this special case.

2017-05-11x86/amd: don't set X86_BUG_SYSRET_SS_ATTRS when running under XenJuergen Gross2-3/+3
When running as Xen pv guest X86_BUG_SYSRET_SS_ATTRS must not be set on AMD cpus. This bug/feature bit is kind of special as it will be used very early when switching threads. Setting the bit and clearing it a little bit later leaves a critical window where things can go wrong. This time window has enlarged a little bit by using setup_clear_cpu_cap() instead of the hypervisor's set_cpu_features callback. It seems this larger window now makes it rather easy to hit the problem. The proper solution is to never set the bit in case of Xen.

As of commits d8f347ba35cf ("nios2: enable earlycon support"), 0dcc0542a006 ("serial: altera_jtaguart: add earlycon support") and 4d9d7d896d77 ("serial: altera_uart: add earlycon support"), the nios2 architecture and the altera_uart/altera_jtaguart drivers support earlycon. Thus, the custom early console implementation for nios2 is no longer necessary to get early boot messages. Remove it and rely fully on earlycon support.
