[Xen-devel] [GIT PULL] xen: fixes and features for 4.12



Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git 
for-linus-4.12b-rc0b-tag

Main changes are:
- a series by Vitaly Kuznetsov to enable building the kernel with Xen
  support but without enabling paravirtualized mode
- a series by Stefano Stabellini adding a new 9pfs xen frontend driver
- a series by Juergen Gross to simplify Xen's cpuid handling by making use
  of cpu capabilities
- a series by Oleksandr Andrushchenko adding(modifying some headers for
  new Xen paravirtualized devices
- a series by Julien Grall for EFI reset_system support under Xen
- and the usual cleanups and corrections

Thanks.

Juergen
