Subject: [PATCH v6 00/15] switch to domheap for Xen page tables
Date: Fri, 24 Apr 2020 15:08:51 +0100 [thread overview]
Message-ID: <cover.1587735799.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 two mini-series:
https://lists.xenproject.org/archives/html/xen-devel/2020-04/msg00730.html
https://lists.xenproject.org/archives/html/xen-devel/2020-04/msg00940.html
Since v1, 9 patches have already been merged. Apart from the first 2
patches in this series, the rest have not seen comments since v1 so they
only contain modifications from my side compared with v1.
---
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.

x86/mm: drop old page table APIs
x86: switch to use domheap page for page tables
