[PATCH 1/4] arm64: topology: Initialise default topology state immediately

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> As a legacy of the way 32 bit ARM did things the topology code uses a null topology map by default and then overwrites it by mapping cores with no information to a cluster by themselves later. In order to make it simpler to reset things as part of recovering from parse failures in firmware information directly set this configuration on init. A core will always be its own sibling so there should be no risk of confusion with firmware provided information.

[RFC PATCH 0/2] Add support for Samsung GH7 PCIe controller

by Jingoo Han

This patch adds support for Samsung GH7 PCIe host controller. Samsung GH7 PCIe controller driver has dependency on the PCI arm64 arch support. So, the Liviu Dudau's patcheset for creating generic host_bridge from device tree [1] and supporting PCI in AArch64 [2] are required. This patch is marked as RFC, so any comment will be welcomed. Thank you.

[PATCH 01/13] video: sh_mobile_lcdcfb depends on meram

by Peter Griffin

From: Arnd Bergmann <arnd(a)arndb.de> The sh_mobile_lcdcfb driver calls interfaces provided by the corresponding "meram" helper. This fails if meram is a module but lcdcfb is built-in. To work around it, this uses special Kconfig magic to only allow lcdcfb to be built if a) both are modules, b) meram is built-in, or c) meram is disabled and the helpers stubbed out Changing meram from 'y' to 'm' now forces clcd to be a module as well, which seems to be the desired behavior.

[PATCH 3.11 155/182] tick-common: Fix wrong check in tick_check_replacement()

It does this as the first check: if (tick_check_percpu(curdev, newdev, smp_processor_id())) return false; Thats wrong. tick_check_percpu() returns true when the device is useable.

[Query]: hrtimers: why don't we consider hrtimers in get_next_timer_interrupt()

by Viresh Kumar

Hi, File: hrtimer.c Function: hrtimer_get_next_event() I was looking closely at what's waking up my system and found this piece of code: ktime_t hrtimer_get_next_event(void) { if (!hrtimer_hres_active()) { find next hrtimer event .... } } Which probably means that: "don't consider hrtimers for getting next timer event if we are running ticks in high resolution mode". And I couldn't understand why is it so? When hres_active isn't set, we run hrtimer handlers from timer handlers, which means that timers would be sufficient in finding the next event and we don't need to check for hrtimers. But when hres_active is set, hrtimers could be set to fire before the next timer event and so we must take them into account. I am new to this whole world of core frameworks and might be missing something very very obvious. But its always better to ask than to ignore and think that things are probably fine and just shut up. Thanks for your patience during my learning curve :) -- viresh
