Subject: [PATCH v2 0/3] x86: Remove vestigal PV Autotranslate pieces
Date: Tue, 13 Dec 2016 16:54:31 +0000	[thread overview]
Message-ID: <1481648074-11455-1-git-send-email-andrew.cooper3@citrix.com> (raw)

Autotranslate PV domains haven't been able to be built for two releases of
Xen, and noone has noticed.  The shadow emulation code for such domains has
never functioned correctly for guests running in a mode different to Xen.

All important change is in patch 3.

Andrew Cooper (3):
  x86/paging: Enforce PG_external == PG_translate == PG_refcounts
  x86/shadow: Drop all emulation for PV vcpus
  x86/traps: Adjust paged-guest handling in the PV pagefault path
