Linux 4.14: Reported regressions as of Sunday, 2017-10-29

[Thorsten Leemhuis]

Hi! Find below my fourth regression report for Linux 4.14. It lists 6
regressions I'm currently aware of; for most of them fixes are in the
work. 4 regressions got fixed since last weeks report; 1 turned out to
not be a regression.

As always: Are you aware of any other regressions? Then please let me
know by mail (a simple bounce or forward in my direction is enough!).
For details see http://bit.ly/lnxregtrackid And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten

P.S.: Sorry, was travelling to kernel summit, that's why there wasn't a
report last week

== Current regressions ==

New default s2idle does not work on Dell XPS 13 9360 with hynix 512GB
Status: Patch to blacklist the problematic machines up for testing
Note: appears to be related to NVMe (and specifically to the particular
Hynix 512G NVMe SSD in the reporter's machine); this seems to be a
regression in 4.13 that is exposed by a change in 4.14; judge yourself
if this should be in the list or not

ARM-TF mainline code with ERRATA fixing, this issue can be dismissed. […]
