[PATCH v3 0/4] use new API for Xen page tables



From: Hongyan Xia <hongyxia@xxxxxxxxxx>

This small series is basically just rewriting functions using the new
API to map and unmap PTEs. Each patch is independent.

Apart from mapping and unmapping page tables, no other functional change
intended.

---
Changed in v3:
- address all comments in v2.
- drop patch 4, since other clean-ups will make it unnecessary.

Changed in v2:
- I kept UNMAP_DOMAIN_PAGE() for now in v2, but I if people say
  in some cases it is an overkill and unmap_domain_page() should be
  used, I am okay with that and can make the change.
- code cleanup and style fixes.
- unmap as early as possible.


Wei Liu (4):
  x86/shim: map and unmap page tables in replace_va_mapping
  x86_64/mm: map and unmap page tables in m2p_mapped
  x86_64/mm: map and unmap page tables in share_hotadd_m2p_table
  x86_64/mm: map and unmap page tables in destroy_m2p_mapping
