[Linux-stable-mirror] [PATCH 2/6] can: ems_usb: cancel urb on -EPIPE and -EPROTO

by Marc Kleine-Budde

From: Martin Kelly <mkelly(a)xevo.com> In mcba_usb, we have observed that when you unplug the device, the driver will endlessly resubmit failing URBs, which can cause CPU stalls. This issue is fixed in mcba_usb by catching the codes seen on device disconnect (-EPIPE and -EPROTO). This driver also resubmits in the case of -EPIPE and -EPROTO, so fix it in the same way.

[Linux-stable-mirror] [PATCH 1/6] can: mcba_usb: cancel urb on -EPROTO

by Marc Kleine-Budde

From: Martin Kelly <mkelly(a)xevo.com> When we unplug the device, we can see both -EPIPE and -EPROTO depending on exact timing and what system we run on. If we continue to resubmit URBs, they will immediately fail, and they can cause stalls, especially on slower CPUs. Fix this by not resubmitting on -EPROTO, as we already do on -EPIPE.

[Linux-stable-mirror] [PATCH v3 3/4] x86/xen: fix boot loader version reported for pvh guests

by Juergen Gross

The boot loader version reported via sysfs is wrong in case of the kernel being booted via the Xen PVH boot entry. it should be 2.12 (0x020c), but it is reported to be 2.18 (0x0212). As the current way to set the version is error prone use the more readable variant (2 << 8) | 12.

Re: [Linux-stable-mirror] [PATCH 1/2] ARM: BUG if jumping to usermode address in kernel mode

by Alex Shi

CC GregKH, since this patch would better to get to stable kernel. This patch also expose a qemu issue which fixed by upstream commit: 3aaf33bebda8d4ffcc0f ARM: avoid faulting on qemu Both of patches are tested in linaro's kernelci and LKFT on stable kernel 4.4/4.9/4.14, no regressions. The lts 3.18 isn't applicable for this patches.

[Linux-stable-mirror] [PATCH] libnvdimm, dax: fix 1GB-aligned namespaces vs physical misalignment

by Dan Williams

The following namespace configuration attempt: # ndctl create-namespace -e namespace0.0 -m devdax -a 1G -f libndctl: ndctl_dax_enable: dax0.1: failed to enable Error: namespace0.0: failed to enable failed to reconfigure namespace: No such device or address ...fails when the backing memory range is not physically aligned to 1G: # cat /proc/iomem | grep Persistent 210000000-30fffffff : Persistent Memory (legacy) In the above example the 4G persistent memory range starts and ends on a 256MB boundary. We handle this case correctly when needing to handle cases that violate section alignment (128MB) collisions against "System RAM", and we simply need to extend that padding/truncation for the 1GB alignment use case.

Re: [Linux-stable-mirror] [PATCH AUTOSEL for 4.14 012/135] ASoC: cs42l56: Fix reset GPIO name in example DT binding

I thought that this one just adjust the example to match the code, and doesn't actually change anything? I was not sure how much we need it since it's not an actual code change, but I thought that this one should go in because it does change buggy example code in documentation that can be copy pasted somewhere. -- Thanks, Sasha
