[patch] xen: off by one errors in multicalls.c
b->args[] has MC_ARGS elements, so the comparison here should be
">=" instead of ">". Otherwise we read past the end of the array
one space.

[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)

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

[PATCH 00/10] REVIEW: Xen patches for 2.6.24
This is my current set of updates to Xen for 2.6.24. This is largely
a bugfix set, and a couple of them are also relevent to 2.6.23.
These are in the pre-x86 merge form; I'll update them once the merge
goes into git.
Quick overview:
- remove some dead code in arch/i386/mm/init.c
- clean up some duplicate includes
- when sending an IPI, yield the vcpu if the destination doesn't have

[PATCH 00/12] xen/paravirt_ops patches for 2.6.24
Hi Linus,
Here's a set of patches to update paravirt_ops and Xen for 2.6.24
A quick overview of the patchset:
paravirt_ops:
Remove the monolithic paravirt_ops structure, and replace it with
smaller structures of related functions. Also, clean up the handling
of lazy mode to make it easier to implement.
x86/mm/init.c: remove a chunk of dead code
Xen:
- remove duplicate includes

[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

[patch 00/28]xen: Xen implementation for paravirt_ops
Hi Andi,
This series of patches implements the Xen paravirt-ops interface. It
applies to 2.6.21-git13 + patches-2.6.21-git7-070507-1.tar.gz (I think
"unwinder" is the only patch which doesn't apply to git13, and the
sched-clock patches are the only ones which this series actually
needs).
Changes since the last posting:
- More netfront review and cleanup
- Added ability to
