[PATCH 0/3] Fix and cleanup for 32-bit PV sysexit
The first patch fixes Xen PV regression introduced by 32-bit rewrite. Unlike the
earlier version it uses ALTERNATIVE instruction and avoids using xen_sysexit
(and sysret32 in compat mode) pv ops, as suggested by Andy. (I ended up patching
TEST with XOR to avoid extra NOPs, even though I said yesterday it would be
wrong. It's not wrong)
As result of this patch irq_enable_sysexit and

As result of this patch irq_enable_sysexit and usergs_sysret32 pv ops are not

[PATCH 0/3] Split up pv-ops
Paravirt ops is currently only capable of either replacing a lot of Linux
internal code or none at all. The are users that don't need all of the
possibilities pv-ops delivers though.
On KVM for example we're perfectly fine not using the PV MMU, thus not
touching any MMU code. That way we don't have to improve pv-ops to become
fast, we just don't compile the MMU parts in!
