[Xen-merge] List of (arch/i386) Xen changes

[Christian Limpach <Christian.Limpach@xxxxxxxxxxxx>]

Hi,

here's the mentioned list of Xen changes for arch/i386.

The list identifies each change, references the files it touches,
indicating the hunks which apply (when doing diff -U 1, * meaning all)
and gives a short description of what the change does.  Some of the
changes need to be refined and we probably need to have some more
maintainable way of identifying the patch hunks.
