[Juergen Gross]

Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-4.13-rc1-tag

xen: features and fixes for 4.13-rc1

Other than fixes and cleanups it contains:
- Support > 32 VCPUs at domain restore
- Support for new sysfs nodes related to Xen
- Some performance tuning for Linux running as Xen guest

There is a minor conflict which can be fixed up easily by:

diff --cc drivers/xen/events/events_base.c

  }
  
  static void enable_dynirq(struct irq_data *data)


Thanks.
