Subject[GIT PULL] xen: features and fixes for 4.19-rc1
Date
Linus,

Please git pull the following tag:

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-4.19-rc1-tag

xen: features and fixes for 4.19-rc1

It contains the following:

- a series to add dma-buf functionality to Xen grant table handling
- a fix for booting the kernel as Xen PVH dom0
- a fix for booting the kernel as a Xen PV guest with CONFIG_DEBUG_VIRTUAL
enabled
- some other minor performance and style fixes


Thanks.

Juergen
