[Xen-devel] [PATCH 00/18] xenpaging changes for 4.0

[Olaf Hering <olaf@xxxxxxxxx>]

Here are some changes for xenpaging in the 4.0 branch.

Its just for review and comments.  All changes are also needed for
xen-unstable, I will prepare a patch queue also for this branch.

There are still issues with xenpaging.
My testsetup is a SLES11 SP1 guest with runlevel 6 as default runlevel to
trigger automatic reboot.  After a few iterations, there will be MMIO emulation
errors.  This happens with a startup delay of 15.0 seconds.

Another issue:
If the startup delay is 0.0, and over_allocated in hvmloader mem_alloc is
forced to be active, the ASSERT in p2m_remove_page() triggers. This is because
the passed mfn and the mfn returned by ->get_entry() do not match.  So far I
have no idea where the appearently missing set_gpfn_from_mfn() should go to.
Normally over_allocated is not set because the XENMEM_populate_physmap call
does not fail.

Olaf
