This changeset reverts two previous corrections, for reasons that escape
me.
First, the domain map is again being confined to NR_CPUS, which I had
submitted a patch to fix recently (yes, I realize the code has a TODO in
there, but those really get forgotten about far too often).
Second, the platform hypercall was reverted back to require all
information to be passed to Xen in one chunk, whereas I recall that even

This sounds possibly problematic to me. The IR should be created with the correct address space to begin with. Changing this in the middle sounds suspect.

[PATCH 0/19] desc_struct integration
Hi,
this is a series of patches that unify the struct desc_struct and friends
across x86_64 and i386. As usual, it provides paravirt capabilities as a
side-effect for x86_64.
I consider the main goal, namely, of unifying the desc_struct, an ongoing
effort, being this the beginning. A lot of old code has to be touched to
accomplish that.
I don't consider this patch ready for inclusion.
