To hit this error required a large io payload (greater than 256k) and a system that maps on a per-page basis. It's possible that large ios could get by fine if the system condensed the sgl list into the first 64 elements. This patch corrects the sg list handling by specifically walking the sg list element by element and attempting to divide the transfer up on a per-sg element boundary. While doing so, it still tries to keep sequences under 256k, but will exceed that rule if a single sg element is larger than 256k.

[PATCH RESEND] userfaultfd: remove uffd flags from vma->vm_flags if UFFD_EVENT_FORK fails

by Mike Rapoport

The fix in commit 0cbb4b4f4c44 ("userfaultfd: clear the vma->vm_userfaultfd_ctx if UFFD_EVENT_FORK fails") cleared the vma->vm_userfaultfd_ctx but kept userfaultfd flags in vma->vm_flags that were copied from the parent process VMA. As the result, there is an inconsistency between the values of vma->vm_userfaultfd_ctx.ctx and vma->vm_flags which triggers BUG_ON in userfaultfd_release(). Clearing the uffd flags from vma->vm_flags in case of UFFD_EVENT_FORK failure resolves the issue.

patch "USB: option: add support for DW5821e" added to usb-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: option: add support for DW5821e 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-next 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 also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From 7bab01ecc6c43da882333c6db39741cb43677004 Mon Sep 17 00:00:00 2001 From: Aleksander Morgado <aleksander(a)aleksander.es> Date: Tue, 24 Jul 2018 01:34:01 +0200 Subject: USB: option: add support for DW5821e The device exposes AT, NMEA and DIAG ports in both USB configurations. The patch explicitly ignores interfaces 0 and 1, as they're bound to other drivers already; and also interface 6, which is a GNSS interface for which we don't have a driver yet.

[PATCH 01/10] KVM: x86: ensure all MSRs can always be KVM_GET/SET_MSR'd

by Paolo Bonzini

Some of the MSRs returned by GET_MSR_INDEX_LIST currently cannot be sent back to KVM_GET_MSR and/or KVM_SET_MSR; either they can never be sent back, or you they are only accepted under special conditions. This makes the API a pain to use. To avoid this pain, this patch makes it so that the result of the get-list ioctl can always be used for host-initiated get and set. Since we don't have a separate way to check for read-only MSRs, this means some Hyper-V MSRs are ignored when written. Arguably they should not even be in the result of GET_MSR_INDEX_LIST, but I am leaving there in case userspace is using the outcome of GET_MSR_INDEX_LIST to derive the support for the corresponding Hyper-V feature.

[PATCH 2/2] ALSA: hda - Sleep for 10ms after entering D3 on Conexant codecs

by Park Ju Hyung

On rare occasions, we are still noticing that the internal speaker spitting out spurious noises even after adding the problematic codec to the list. Adding a 10ms artificial delay before rebooting fixes the issue entirely. Patch for Realtek codecs also adds the same amount of delay after entering D3.

[PATCH 1/2] ALSA: hda - Turn CX8200 into D3 as well upon reboot

by Park Ju Hyung

As an equivalent codec with CX20724, CX8200 is also subject to the reboot bug. Late 2017 and 2018 LG Gram and some HP Spectre laptops are known victims to this issue, causing extremely loud noises upon reboot. Now that we know that this bug is subject to multiple codecs, fix the comment as well.

patch "USB: option: add support for DW5821e" added to usb-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: option: add support for DW5821e 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-testing 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 be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 7bab01ecc6c43da882333c6db39741cb43677004 Mon Sep 17 00:00:00 2001 From: Aleksander Morgado <aleksander(a)aleksander.es> Date: Tue, 24 Jul 2018 01:34:01 +0200 Subject: USB: option: add support for DW5821e The device exposes AT, NMEA and DIAG ports in both USB configurations. The patch explicitly ignores interfaces 0 and 1, as they're bound to other drivers already; and also interface 6, which is a GNSS interface for which we don't have a driver yet.
