Merge tag 'for-linus-4.12b-rc0b-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen updates from Juergen Gross:
"Xen fixes and featrues for 4.12. The main changes are:
- enable building the kernel with Xen support but without enabling
paravirtualized mode (Vitaly Kuznetsov)
- add a new 9pfs xen frontend driver (Stefano Stabellini)
- simplify Xen's cpuid handling by making use of cpu capabilities
(Juergen Gross)
- add/modify some headers for new Xen paravirtualized devices
(Oleksandr Andrushchenko)
- EFI reset_system support under Xen (Julien Grall)
- and the usual cleanups and corrections"
