[PATCH 0 of 4] mm+paravirt+xen: add pte read-modify-write abstraction
Hi all,
This little series adds a new transaction-like abstraction for doing
RMW updates to a pte, hooks it into paravirt_ops, and then makes use
of it in Xen.
The basic problem is that mprotect is very slow under Xen (up to 50x
slower than native), primarily because of the
ptent = ptep_get_and_clear(mm, addr, pte);
ptent = pte_modify(ptent, newprot);
/* ... */

[PATCH 0 of 4] mm+paravirt+xen: add pte read-modify-write abstraction (take 2)
Hi all,

grounds that it isn't really a general pte-modification interface. ]

[patch 00/24] Xen-paravirt_ops: Xen guest implementation for paravirt_ops interface
Hi Andi,
This patch series implements the Linux Xen guest as a paravirt_ops
backend. The features in implemented this patch series are:
* domU only
* UP only (most code is SMP-safe, but there's no way to create a new vcpu)
* writable pagetables, with late pinning/early unpinning
(no shadow pagetable support)
* supports both PAE and non-PAE modes
* xen hvc console (console=hvc0)

[PATCH 00/25] xen: Xen implementation for paravirt_ops
Hi Andi,
This series of patches implements the Xen paravirt-ops interface.
It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops
patches I posted.
This patch generally restricts itself to Xen-specific parts of the tree,
though it does make a few small changes elsewhere.
These patches include:
- some helper routines for allocating address space and walking pagetables
- Xen
