This is a note to let you know that I've just added the patch titled eventpoll.h: fix epoll event masks to the 4.9-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: eventpoll.h-fix-epoll-event-masks.patch and it can be found in the queue-4.9 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 foo@baz Sun Mar 18 16:55:33 CET 2018 From: Greg KH <gregkh(a)linuxfoundation.org> Date: Wed, 8 Mar 2017 19:03:03 +0100 Subject: eventpoll.h: fix epoll event masks From: Greg KH <gregkh(a)linuxfoundation.org> [ Upstream commit 6f051e4a685b768f3704c7c069aa1edee3010622 ] [resend due to me forgetting to cc: linux-api the first time around I posted these back on Feb 23] From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> When userspace tries to use these defines, it complains that it needs to be an unsigned 1 that is shifted, so libc implementations have to create their own version. Fix this by defining it properly so that libcs can just use the kernel uapi header.

Patch "EDAC, altera: Fix peripheral warnings for Cyclone5" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled EDAC, altera: Fix peripheral warnings for Cyclone5 to the 4.9-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: edac-altera-fix-peripheral-warnings-for-cyclone5.patch and it can be found in the queue-4.9 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 foo@baz Sun Mar 18 16:55:33 CET 2018 From: Thor Thayer <thor.thayer(a)linux.intel.com> Date: Wed, 5 Apr 2017 13:01:02 -0500 Subject: EDAC, altera: Fix peripheral warnings for Cyclone5 From: Thor Thayer <thor.thayer(a)linux.intel.com> [ Upstream commit 25b223ddfe2a557307c05fe673e09d94ae950877 ] The peripherals' RAS functionality only exist on the Arria10 SoCFPGA. The Cyclone5 initialization generates EDAC warnings when the peripherals aren't found in the device tree. Fix by checking for Arria10 in the init functions.

The former creates a regmap and writes to several register to clear its configuration to a known default. The latter initializes various clocks. This includes enabling the bus clock for register access and creating the dotclock. In order for the first step's writes to work, the bus clock must be enabled which is done in the second step. but the dotclock's ops use the regmap created in the first step.
