Introducing paravirt_ops for x86_64
Hi folks,
After some time away from it, and a big rebase as a consequence, here is
the updated version of paravirt_ops for x86_64, heading to inclusion.
Your criticism is of course, very welcome.
Have fun

[PATCH 0/7] x86 paravirtualization infrastructure
The following patches introduce the core infrastructure needed to
paravirtualize the 32-bit x86 Linux kernel. This is done by moving
virtualization sensitive insn's or code paths to a function table,
paravirt_ops. This structure can be populated with hypervisor specific
calls or native stubs and currently support running on bare metal, VMI,
Xen, or Lhype. These patches apply to

[PATCH 00 of 38] xen: add more Xen dom0 support
Hi Ingo,
Here''s the chunk of patches to add Xen Dom0 support (it''s probably
worth creating a new xen/dom0 topic branch for it).
A dom0 Xen domain is basically the same as a normal domU domain, but
it has extra privileges to directly access hardware. There are two
issues to deal with:
- translating to and from the domain''s pseudo-physical addresses and
real machine
