#     Merge tag 'for-linus-5.3a-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
#     
#     Pull xen fixes from Juergen Gross:
#     
#      - a small cleanup
#     
#      - a fix for a build error on ARM with some configs
#     
#      - a fix of a patch for the Xen gntdev driver
#     
#      - three patches for fixing a potential problem in the swiotlb-xen
#        driver which Konrad was fine with me carrying them through the Xen
#        tree
#     
#     * tag 'for-linus-5.3a-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
#       xen/swiotlb: remember having called xen_create_contiguous_region()
#       xen/swiotlb: simplify range_straddles_page_boundary()
#       xen/swiotlb: fix condition for calling xen_destroy_contiguous_region()
#       xen: avoid link error on ARM
#       xen/gntdev.c: Replace vm_map_pages() with vm_map_pages_zero()
#       xen/pciback: remove set but not used variable 'old_state'
