This series improves the performance of Xen PV guests when doing page faults (32-bit guests only) and context switches.
Can an x86 maintainer ack patch 3 (x86: add desc_equal() to compare GDT descriptors) so this series can go via Konrad's tree? The other patches are Xen-specific.
Changes since v1:
- fix (very!) slow boot on x86_64 by avoiding hypercalls when building the initial page tables. These updates were mostly a) done to unpinned pages and b) often had invalid MFNs that Xen warns about.
- When building the initial page tables, zero PTEs for pages without an MFN yet.
- add desc_equal() instead of open coding it.
