Hi Linus,
Regular fixes for final, there is a ttm regression fix, dp-mst fix,
one amdgpu revert, two i915 fixes, and some misc fixes for sun4i,
xlnx, and vc4.
All pretty quiet and don't think we have any known outstanding regressions.
Dave.

Linus,
Please git pull the following tag:
git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git
for-linus-5.11-rc8-tag
xen: branch for v5.11-rc8
It contains a single fix for an issue introduced in 5.11: when running
as a Xen guest on Arm systems the kernel will hang during boot.
Thanks.

No need for the braces.
The PHY core already resets the PHY before .config_init() if a
.soft_reset() op is registered. Drop the open-coded ip1xx_reset().

Since a call instruction on every supported
architecture is at least four bytes, it is safe
to just stor

During the 5.11 test cycle I caught a rare but repeatable problem when
after a day uptime happens "BUG at mm/zswap.c:1275!". I am still not
having an idea how to reproduce it, but maybe the authors of this code
could explain what happens here?
