Juergen Gross 2cf1372141 SUPPORT.md: clarify support of untrusted driver domains with oxenstored
Add a support statement for the scope of support regarding different
Xenstore variants. Especially oxenstored does not (yet) have security
support of untrusted driver domains, as those might drive oxenstored
out of memory by creating lots of watch events for the guests they are
servicing.

Add a statement regarding Live Update support of oxenstored.

This is part of XSA-326.

George Dunlap c6ee6d4ec3 SUPPORT.md: Un-shimmed 32-bit PV guests are no longer supported
The support status of 32-bit guests doesn't seem particularly useful.

With it changed to fully unsupported outside of PV-shim, adjust the PV32
Kconfig default accordingly.

Julien Grall ddb39ba714 SUPPORT.MD: Clarify the support state for the Arm SMMUv{1, 2} drivers
SMMUv{1, 2} are both marked as security supported, so we would
technically have to issue an XSA for any IOMMU security bug.

However, at the moment, device passthrough is not security supported
on Arm and there is no plan to change that in the next few months.

Therefore, mark Arm SMMUv{1, 2} as supported but not security supported.

Ian Jackson 5784d1e942 SUPPORT.md: Desupport qemu trad except stub dm
While investigating XSA-335 we discovered that many upstream security
fixes were missing.  It is not practical to backport them.  There is
no good reason to be running this very ancient version of qemu, except
that it is the only way to run a stub dm which is currently supported
by upstream.

This commits (more or less) this file to be processed with pandoc,
rather than other markdown processors.  There is, unfortunately, no
widely-accepted way to declare a title for the document.

I tested feeding the document to markdown(1) on Debian jessie and it
reproduced the % line as if it were simple text.  I guess many other
markdown processors will do something similarly tolerable.  My
internet searches did not discover a markdown processor that used
lines starting with % for something else.
