[PATCH RFC 0/6] xen/arm: mm: Add limited support for superpages



From: Julien Grall <jgrall@xxxxxxxxxx>

Hi all,

This is a first attempt to add superpage mapping in
xen_pt_update_entry(). The end goal if to remove open-coding mappings
which will help to:
  1) get better compliance with the Arm memory model
  2) pave the way for other page size (64KB, 16KB).

For now, only the open-code mappings for the Device-Tree is reworked.
The others will be added later.

Julien Grall (5):
  xen/arm: mm: Remove ; at the end of mm_printk()
  xen/arm: setup: Call unregister_init_virtual_region() after the last
    init function
  xen/arm: mm: Allow other mapping size in xen_pt_update_entry()
  xen/arm: mm: Don't open-code Xen PT update in remove_early_mappings
  xen/arm: mm: Re-implement early_fdt_map() using map_pages_to_xen()

Stefano Stabellini (1):
  xen/arm: mm: Remove special case for CPU0 in dump_hyp_walk()
