Subject: [PATCH v8 00/15] switch to domheap for Xen page tables
Date: Mon, 27 Jul 2020 15:21:50 +0100 [thread overview]
Message-ID: <cover.1595857947.git.hongyxia@amazon.com> (raw)
From: Hongyan Xia <hongyxia@amazon.com>
This series rewrites all the remaining functions and finally makes the
switch from xenheap to domheap for Xen page tables, so that they no
longer need to rely on the direct map, which is a big step towards
removing the direct map.
This series depends on the following mini-series:

---
Changed in v8:
- address comments in v7.
- rebase
Changed in v7:
- rebase and cleanup.
- address comments in v6.
- add alloc_map_clear_xen_pt() helper to simplify the patches in this
series.
Changed in v6:
- drop the patches that have already been merged.
- rebase and cleanup.
- rewrite map_pages_to_xen() and modify_xen_mappings() in a way that
does not require an end_of_loop goto label.
