2017-06-03ARM: sun8i: a83t: Add device node for PRCMChen-Yu Tsai
The A83T's PRCM has the same set of clocks and resets as the A64. However, a few dividers are different. And due to the lack of a low speed 32.768 kHz oscillator, a few of the clock parents are different. The PRCM also has controls for various power domains. These are not supported yet, neither in software nor in the device tree binding. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

2017-06-01ARM: dts: augment Moxa and Aspeed DTS for FTTMR010Linus Walleij
This augments the Moxa Art and Aspeed device trees to: - Explicitly name the clock "PCLK" as the Faraday FTTMR010 names it. - List the Moxa timer as compatible with the Faradat FTTMR010 vanilla version. - Add a comment that the Aspeed driver is a Faraday FTTMR010 derivative. - Pass all IRQs to the timer from Aspeed: they are all there so they should be in the device tree, we only use the first one anyways.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt This is a first set of Gemini DTS patches for the v4.13 cycle. This adds the reset and clock lines to the Gemini core DTS SoC. These bindings have been ACKed by the DT maintainer Rob. The reset driver is going to be merged by the reset maintainer. The clock driver is going to be merged by the clock maintainers. Each of these have their macro defines coming with them, split off as separate patches. A post-rc1 patch will be sumbitted for switching the numerical values to the defined macros in line with the ARM SoC DT header merge strategy. * tag 'gemini-v4.13-dts-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik: ARM: dts: Add clocks to the Gemini SoC ARM: dts: Add the Gemini reset controller dt-bindings: Augment Gemini for clocks, resets Signed-off-by: Olof Johansson <olof@lixom.net>

It is also fine to leave interrupts enabled during this time as there's only one CPU running, and on_each_cpu() means to only run on the current CPU. If early_boot_irqs_disabled is set, it is safe to run cpu_flush_range() with interrupts disabled. Don't trigger a BUG_ON() in that case.

2017-05-26selftests/ftrace: Add a testcase for many kprobe eventsMasami Hiramatsu
Add a testcase to test kprobes via ftrace interface with many concurrent kprobe events. This tries to add many kprobe events (up to 256) on kernel functions. To avoid making ftrace-based kprobes (kprobes on fentry), it skips first N bytes (on x86 N=5, on ppc or arm N=4) of function entry. After that, it enables all those events, disable it, and remove it. Since the unoptimization buffer reclaiming will be delayed, after removing events, it will wait enough time.

2017-05-26kprobes/x86: Fix to set RWX bits correctly before releasing trampolineMasami Hiramatsu
Fix kprobes to set(recover) RWX bits correctly on trampoline buffer before releasing it. Releasing readonly page to module_memfree() crash the kernel. Without this fix, if kprobes user register a bunch of kprobes in function body (since kprobes on function entry usually use ftrace) and unregister it, kernel hits a BUG and crash.

ftrace_hash is being kfree'ed in ftrace_graph_release(), however the ->buckets field is not.
