2014-10-03ARM64: make of_device_ids constUwe Kleine-König
of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. So mark the only non-const struct in arch/arm64 as const, too. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2014-10-03PM / Domains: Rename cpu_data to cpuidle_dataUlf Hansson
The "cpu_data" are defined for some archs and thus conflicting with the "cpu_data" member in the struct gpd_cpu_data. This causes a compiler error for those archs. Let's fix it by rename the member to cpuidle_data. In this context it also seems appropriate to rename the struct to gpd_cpuidle_data to better reflect its use.

2014-10-03cpufreq: cpufreq-dt: fix potential double put of cpu OF nodeLucas Stach
If cpufreq_generic_init() fails we jump into the resource cleanup path which contains a of_node_put() call. Another instance of this has already been called at that time resulting a double decrement of the refcount. Fix this by calling of_node_put() only after we are sure that nothing has gone wrong.

2014-10-03cpufreq: cpu0: rename driver and internals to 'cpufreq_dt'Viresh Kumar
The naming convention of this driver was always under the scanner, people complained that it should have a more generic name than cpu0, as it manages all CPUs that are sharing clock lines. Also, in future it will be modified to support any number of clusters with separate clock/voltage lines. Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

2014-10-03m68k: Disable/restore interrupts in hwreg_present()/hwreg_write()Geert Uytterhoeven
hwreg_present() and hwreg_write() temporarily change the VBR register to another vector table. This table contains a valid bus error handler only, all other entries point to arbitrary addresses. If an interrupt comes in while the temporary table is active, the processor will start executing at such an arbitrary address, and the kernel will crash. While most callers run early, before interrupts are enabled, or explicitly disable interrupts, Finn Thain pointed out that macsonic has one callsite that doesn't, causing intermittent boot crashes. There's another unsafe callsite in hilkbd. Fix this for good by disabling and restoring interrupts inside hwreg_present() and hwreg_write(). Explicitly disabling interrupts can be removed from the callsites later.

2014-10-03powerpc: Don't build powernv for other platform defconfigsMichael Ellerman
Because powernv arrived after these other platforms, the defconfigs didn't have PPC_POWERNV disabled, and being default y it gets turned on. If we're going to bother having defconfigs for the specific platforms then they should only build the code required for those platforms. The grab bag of everything config is ppc64_defconfig.

2014-10-02Revert "serial/core: Initialize the console pm state"Greg Kroah-Hartman
This reverts commit a86713b1536c818972675e6dd8c6e738f0379f1d. Kevin Hilman writes: Multiple boot failures on ARM[1] were bisected down to this patch. How was this patch tested, and on which platforms? Also, the changelog states that this should be done only for UART_CAP_SLEEP, but the patch does it for every UART. Greg, I suggest this patch be dropped from tty-next until it has been better described and tested.

2014-10-03powerpc/iommu/ddw: Fix endiannessAlexey Kardashevskiy
rtas_call() accepts and returns values in CPU endianness. The ddw_query_response and ddw_create_response structs members are defined and treated as BE but as they are passed to rtas_call() as (u32 *) and they get byteswapped automatically, the data is CPU-endian. This fixes ddw_query_response and ddw_create_response definitions and use. of_read_number() is designed to work with device tree cells - it assumes the input is big-endian and returns data in CPU-endian. However due to the ddw_create_response struct fix, create.addr_hi/lo are already CPU-endian so do not byteswap them. ddw_avail is a pointer to the "ibm,ddw-applicable" property which contains 3 cells which are big-endian as it is a device tree. rtas_call() accepts a RTAS token in CPU-endian. This makes use of of_property_read_u32_array to byte swap and avoid the need for a number of be32_to_cpu calls.
