2016-10-18drm/imx: ipuv3-plane: Skip setting u/vbo only when we don't need modesetLiu Ying
We added active plane reconfiguration support by forcing a full modeset operation. So, looking at old_plane_state->fb to determine whether we need to set u/v offset(aka, u/vbo for IPUv3) in ipu_plane_atomic_set_base() or not is no more correct. Instead, we should do that only when we don't need modeset.

We added active plane reconfiguration support by forcing a full modeset operation. So, looking at old_plane_state->fb to determine whether we need to switch EBA buffer(for hardware double buffering) in ipu_plane_atomic_set_base() or not is no more correct. Instead, we should do that only when we don't need modeset, otherwise, we initialize the two EBA buffers with the buffer address.

2016-10-17clk: hi6220: use CLK_OF_DECLARE_DRIVER for sysctrl and mediactrl clock initShawn Guo
The hi6220-sysctrl and hi6220-mediactrl are not only clock provider but also reset controller. It worked fine that single sysctrl/mediactrl device node in DT can be used to initialize clock driver and populate platform device for reset controller. But it stops working after commit 989eafd0b609 ("clk: core: Avoid double initialization of clocks") gets merged. The commit sets flag OF_POPULATED during clock initialization to skip the platform device populating for the same device node. On hi6220, it effectively makes hi6220-sysctrl reset driver not probe any more. The patch changes hi6220 sysctrl and mediactrl clock init macro from CLK_OF_DECLARE to CLK_OF_DECLARE_DRIVER, so that the reset driver using the same hardware block can continue working.

The commit 9b4cac33adc7 ("clk: max77686: Migrate to clk_hw based OF and registration APIs") converted the driver to use the new provider API to register clocks using clk_hw. But unfortunately, in the conversion it missed to set the num_clks value which lead to the following error when trying to register a clk provider: [ 1.963782] of_clk_max77686_get: invalid index 0 [ 1.967460] ERROR: could not get clock /rtc@10070000:rtc_src(1) [ 1.973638] s3c-rtc 10070000.rtc: failed to find rtc source clock Fix it by correctly set the max77686_clk_driver_data num_clks member.

pkey_set() and pkey_get() were syscalls present in older versions of the protection keys patches. The syscall number definitions were inadvertently left in place. This patch removes them. I did a git grep and verified that these are the last places in the tree that these appear, save for the protection_keys.c tests and Documentation. Those spots talk about functions called pkey_get/set() which are wrappers for the direct PKRU instructions, not the syscalls.

2016-10-17ARM: dts: fix the SD card on the SnowballLinus Walleij
This fixes a very annoying regression on the Snowball SD card that has been around for a while. It turns out that the device tree does not configure the direction pins properly, nor sets up the pins for the voltage converter properly at boot. Unless all things are correctly set up, the feedback clock will not work, and makes the driver spew messages in the console (but it works, very slowly): root@Ux500:/ mount /dev/mmcblk0p2 /mnt/ [ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!

Add in the SDR12 and SDR25 modes which this host can do without any problems. I don't know if this has ever been correct, sadly. It works after this patch.

Commit 8a71f0c656e0 ("arm64: sysreg: replace open-coded mrs_s/msr_s with {read,write}_sysreg_s") introduced a write_sysreg_s macro for writing to system registers that are not supported by binutils.

2016-10-17generic syscalls: kill cruft from removed pkey syscallsDave Hansen
pkey_set() and pkey_get() were syscalls present in older versions of the protection keys patches. They were fully excised from the x86 code, but some cruft was left in the generic syscall code. The C++ comments were intended to help to make it more glaring to me to fix them before actually submitting them. That technique worked, but later than I would have liked.

2016-10-17arm64: kaslr: keep modules close to the kernel when DYNAMIC_FTRACE=yArd Biesheuvel
The RANDOMIZE_MODULE_REGION_FULL Kconfig option allows KASLR to be configured in such a way that kernel modules and the core kernel are allocated completely independently, which implies that modules are likely to require branches via PLT entries to reach the core kernel. The dynamic ftrace code does not expect that, and assumes that it can patch module code to perform a relative branch to anywhere in the core kernel. This may result in errors such as branch_imm_common: offset out of range ------------[ cut here ]------------ WARNING: CPU: 3 PID: 196 at kernel/trace/ftrace.c:1995 ftrace_bug+0x220/0x2e8 Modules linked in: CPU: 3 PID: 196 Comm: systemd-udevd Not tainted 4.8.0-22-generic #24 Hardware name: AMD Seattle/Seattle, BIOS 10:34:40 Oct 6 2016 task: ffff8d1bef7dde80 task.stack: ffff8d1bef6b0000 PC is at ftrace_bug+0x220/0x2e8 LR is at ftrace_process_locs+0x330/0x430 So make RANDOMIZE_MODULE_REGION_FULL mutually exclusive with DYNAMIC_FTRACE at the Kconfig level.

After Jesper commit back in linux-3.18, we trigger a lockdep splat in proc_create_data() while allocating memory from pktgen_change_name(). This patch converts t->if_lock to a mutex, since it is now only used from control path, and adds proper locking to pktgen_change_name() 1) pktgen_thread_lock to protect the outer loop (iterating threads) 2) t->if_lock to protect the inner loop (iterating devices) Note that before Jesper patch, pktgen_change_name() was lacking proper protection, but lockdep was not able to detect the problem.

In acpi_get_pmu_hw_inf we pass the address of a local variable to IS_ERR(), which doesn't make sense, as the pointer must be a real, valid pointer. This doesn't cause a functional problem, as IS_ERR() will evaluate as false, but the check is bogus and causes static checkers to complain. Remove the bogus check.
