[Linux-stable-mirror] Patch "ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7" 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: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7 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-kirkwood-fix-pin-muxing-of-mpp7-on-openblocks-a7.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 56aeb07c914a616ab84357d34f8414a69b140cdf Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni <thomas.petazzoni(a)free-electrons.com> Date: Thu, 4 Jan 2018 17:53:12 +0100 Subject: ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7 From: Thomas Petazzoni <thomas.petazzoni(a)free-electrons.com> commit 56aeb07c914a616ab84357d34f8414a69b140cdf upstream. MPP7 is currently muxed as "gpio", but this function doesn't exist for MPP7, only "gpo" is available. This causes the following error: kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7 pinctrl core: failed to register map default (6): invalid type given kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22 kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22 kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22 So the pinctrl driver is not probed, all device drivers (including the UART driver) do a -EPROBE_DEFER, and therefore the system doesn't really boot (well, it boots, but with no UART, and no devices that require pin-muxing). Back when the Device Tree file for this board was introduced, the definition was already wrong. The pinctrl driver also always described as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11, a hog pin failing to be muxed was turned from a simple warning to a hard error that caused the entire pinctrl driver probe to bail out. This is probably the result of commit 6118714275f0a ("pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()"). This commit fixes the Device Tree to use the proper "gpo" function for MPP7, which fixes the boot of OpenBlocks A7, which was broken since Linux 4.11.

[Linux-stable-mirror] 4.9 backport request: perf tools: Fix build with ARCH=x86_64

by Tuomas Tynkkynen

Hi Greg, Please apply the following commit from 4.10 to 4.9.y to fix perf build under certain conditions: commit 7a759cd8e8272ee18922838ee711219c7c796a31 Author: Jiada Wang <jiada_wang(a)mentor.com> Date: Sun Apr 9 20:02:37 2017 -0700 perf tools: Fix build with ARCH=x86_64 With commit: 0a943cb10ce78 (tools build: Add HOSTARCH Makefile variable) when building for ARCH=x86_64, ARCH=x86_64 is passed to perf instead of ARCH=x86, so the perf build process searchs header files from tools/arch/x86_64/include, which doesn't exist. The following build failure is seen: In file included from util/event.c:2:0: tools/include/uapi/linux/mman.h:4:27: fatal error: uapi/asm/mman.h: No such file or directory compilation terminated. Fix this issue by using SRCARCH instead of ARCH in perf, just like the main kernel Makefile and tools/objtool's.

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 7a759cd8e8272ee18922838ee711219c7c796a31 Mon Sep 17 00:00:00 2001 From: Jiada Wang <jiada_wang(a)mentor.com> Date: Sun, 9 Apr 2017 20:02:37 -0700 Subject: perf tools: Fix build with ARCH=x86_64 From: Jiada Wang <jiada_wang(a)mentor.com> commit 7a759cd8e8272ee18922838ee711219c7c796a31 upstream. With commit: 0a943cb10ce78 (tools build: Add HOSTARCH Makefile variable) when building for ARCH=x86_64, ARCH=x86_64 is passed to perf instead of ARCH=x86, so the perf build process searchs header files from tools/arch/x86_64/include, which doesn't exist. The following build failure is seen: In file included from util/event.c:2:0: tools/include/uapi/linux/mman.h:4:27: fatal error: uapi/asm/mman.h: No such file or directory compilation terminated. Fix this issue by using SRCARCH instead of ARCH in perf, just like the main kernel Makefile and tools/objtool's.
