[GIT PULL] [lsk-v4.4-android] First pull request for linaro-android v4.4 topic branch

by Amit Pundir

Hi Mark, Alex, Please consider following linaro-android pull request (based on recently tagged android-4.4 stable kernel in AOSP) for "linux-linaro-lsk-v4.4-android" LSK branch. This pull request is a simple merge of android-4.4 and linux-linaro-lsk-v4.4-android trees with no merge conflict, and it doesn't carry any additional linaro-android fixes for now. Regards, Amit Pundir The following changes since commit 34f6d2c9d12a97271d55c7b204443b2da9e6c29e: Merge tag 'v4.4.1' into linux-linaro-lsk-v4.4 (2016-02-05 19:31:55 +0000) are available in the git repository at: git://android.git.linaro.org/kernel/linaro-android.git lsk-v4.4-android for you to fetch changes up to 02bbd06e489a9f56910973535152d3ec47f3fdcc: Merge branch 'android-4.4' of https://android.googlesource.com/kernel/common (2016-02-18 00:20:12 +0530) ---------------------------------------------------------------- Alex Ray (1): ARM64: add option to build Image.gz/dtb combo Alistair Strachan (2): video: adf: export the adf_attachment_allow symbol to modules. video: adf: use rb_erase in adf_obj_destroy.

[PATCH] ARM64: ACPI: Update documentation for latest specification version

by al.stone＠linaro.org

From: Al Stone <al.stone(a)linaro.org> The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events. This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64.

[RFC V3 PATCH] kernfs: create raw version kernfs_path_len and kernfs_path

by Yang Shi

commit 5634cc2aa9aebc77bc862992e7805469dcf83dac ("writeback: update writeback tracepoints to report cgroup") made writeback tracepoints report cgroup writeback, but it may trigger the below bug on -rt kernel since kernfs_path and kernfs_path_len are called by tracepoints, which acquire sleeping lock.
