patch "USB: serial: iuu_phoenix: fix DMA from stack" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: iuu_phoenix: fix DMA from stack to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 54d0a3ab80f49f19ee916def62fe067596833403 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Mon, 4 Jan 2021 15:50:07 +0100 Subject: USB: serial: iuu_phoenix: fix DMA from stack Stack-allocated buffers cannot be used for DMA (on all architectures) so allocate the flush command buffer using kmalloc().

You will need the preparatory refactoring patch commit 5d78533a0c53af9659227c803df944ba27cd56e0 Author: Uwe Kleine-König <u.kleine-koenig(a)pengutronix.de> Date: Thu Sep 24 12:52:55 2020 +0200 rtc: pcf2127: move watchdog initialisation to a separate function And if documentation is supposed to be kept up-to-date in the -stable trees, you can pick commit 320d159e2d63a97a40f24cd6dfda5a57eec65b91 Author: Rasmus Villemoes <rasmus.villemoes(a)prevas.dk> Date: Fri Dec 18 11:10:53 2020 +0100 dt-bindings: rtc: add reset-source property Thanks, Rasmus

[PATCH v4 1/3] iommu/vt-d: Move intel_iommu info from struct intel_svm to struct intel_svm_dev

by Liu Yi L

Current struct intel_svm has a field to record the struct intel_iommu pointer for a PASID bind. And struct intel_svm will be shared by all the devices bind to the same process. The devices may be behind different DMAR units. As the iommu driver code uses the intel_iommu pointer stored in intel_svm struct to do cache invalidations, it may only flush the cache on a single DMAR unit, for others, the cache invalidation is missed. As intel_svm struct already has a device list, this patch just moves the intel_iommu pointer to be a field of intel_svm_dev struct.
