Linus,
Please git pull the following tag:
git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-4.19c-rc4-tag
xen: fixes for 4.19-rc4
It contains some minor cleanups and fixes and:
- a new knob for controlling scrubbing of pages returned by the Xen balloon driver to the Xen hypervisor to address a boot performance issue seen in large guests booted pre-ballooned
- a fix of a regression in the gntdev driver which made it impossible to use fully virtualized guests (HVM guests) with a 4.19 based dom0
- a fix in Xen cpu hotplug functionality which could be triggered by wrong admin commands (setting number of active vcpus to 0)
One further note: the patches have all been under test for several days in another branch. This branch has been rebased in order to avoid merge conflicts.
Thanks.
Juergen
