[PATCH RFC 0/6] xen/arm: mm: Add limited support for superpages
From: Julien Grall <>

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()
