#     Merge tag 'for-linus-4.19b-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
#     
#     Pull xen fixes from Juergen Gross:
#     
#      - minor cleanup avoiding a warning when building with new gcc
#     
#      - a patch to add a new sysfs node for Xen frontend/backend drivers to
#        make it easier to obtain the state of a pv device
#     
#      - two fixes for 32-bit pv-guests to avoid intermediate L1TF vulnerable
#        PTEs
#     
#     * tag 'for-linus-4.19b-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
#       x86/xen: remove redundant variable save_pud
#       xen: export device state to sysfs
#       x86/pae: use 64 bit atomic xchg function in native_ptep_get_and_clear
#       x86/xen: don't write ptes directly in 32-bit PV guests
