According to the comment added to exynos_dt_pmu_match[] in commit 8b283c025443 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"), the RTC is not able to wake up the system through the PMU on Exynos5410, unlike Exynos5420. However, when the RTC DT node got added, it was a straight copy of the Exynos5420 node, which now causes a warning from dtc. This removes the incorrect interrupt-parent, which should get the interrupt working and avoid the warning.

The invalid assignment was a mistake by me during submission of the DTSI where I was looking for the reference, didn't find it and didn't fill it in.

With CONFIG_KASAN, we get an overly long stack frame due to inlining the register access functions: drivers/media/tuners/r820t.c: In function 'generic_set_freq.isra.7': drivers/media/tuners/r820t.c:1334:1: error: the frame size of 2880 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] This is caused by a gcc bug that has now been fixed in gcc-8. To work around the problem, we can pass the register data through a local variable that older gcc versions can optimize out as well.

Patch "ARM: dts: s5pv210: add interrupt-parent for ohci" has been added to the 3.18-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: dts: s5pv210: add interrupt-parent for ohci to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-dts-s5pv210-add-interrupt-parent-for-ohci.patch and it can be found in the queue-3.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 5c1037196b9ee75897c211972de370ed1336ec8f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Wed, 10 Jan 2018 17:10:11 +0100 Subject: ARM: dts: s5pv210: add interrupt-parent for ohci From: Arnd Bergmann <arnd(a)arndb.de> commit 5c1037196b9ee75897c211972de370ed1336ec8f upstream. The ohci-hcd node has an interrupt number but no interrupt-parent, leading to a warning with current dtc versions: arch/arm/boot/dts/s5pv210-aquila.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 arch/arm/boot/dts/s5pv210-goni.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 arch/arm/boot/dts/s5pv210-smdkc110.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 arch/arm/boot/dts/s5pv210-smdkv210.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 arch/arm/boot/dts/s5pv210-torbreck.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 As seen from the related exynos dts files, the ohci and ehci controllers always share one interrupt number, and the number is the same here as well, so setting the same interrupt-parent is the reasonable solution here.

FAILED: patch "[PATCH] ovl: hash directory inodes for fsnotify" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 31747eda41ef3c30c09c5c096b380bf54013746a Mon Sep 17 00:00:00 2001 From: Amir Goldstein <amir73il(a)gmail.com> Date: Sun, 14 Jan 2018 18:35:40 +0200 Subject: [PATCH] ovl: hash directory inodes for fsnotify fsnotify pins a watched directory inode in cache, but if directory dentry is released, new lookup will allocate a new dentry and a new inode. Directory events will be notified on the new inode, while fsnotify listener is watching the old pinned inode. Hash all directory inodes to reuse the pinned inode on lookup. Pure upper dirs are hashes by real upper inode, merge and lower dirs are hashed by real lower inode. The reference to lower inode was being held by the lower dentry object in the overlay dentry (oe->lowerstack[0]). Releasing the overlay dentry may drop lower inode refcount to zero. Add a refcount on behalf of the overlay inode to prevent that. As a by-product, hashing directory inodes also detects multiple redirected dirs to the same lower dir and uncovered redirected dir target on and returns -ESTALE on lookup. The reported issue dates back to initial version of overlayfs, but this patch depends on ovl_inode code that was introduced in kernel v4.13.
