[PATCH 0 of 3] RFC Paging support for AMD NPT V2
There has been some progress, but still no joy. Definitely not intended for
inclusion at this point.
Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table
sharing.
Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit
hypervisor and Win 7 guest).
Hongkaixing, I incorporated your suggestion in patch 2, so I should add your
Signed-off-by eventually.

The merge of PAE support introduced the intpte_t type and PRIpte format
specifier. Most of the shadow mode code was fixed, but debugging
printks were not; this broke the compile if shadow mode debugging was
enabled.
The attached patch should fix the problem. Not tested with PAE enabled,
but it shouldn''t make anything worse than it alr...

[PATCH] Fix performance problems with mprotect()
While working on a database scaling problem using a SAP database test suite we discovered that these enterprise level large shared memory databases are very heavy users of mprotect(), to the extent that the performance overhead in current Xenolinux impacts scaling beyond a few cpus quite badly. A single cpu run under Xen has a nominal impact, but scaling out to 8 cpus results in a performance of

RFC: [0/2] Remove netloop by lazy copying in netback
Hi Keir:
These two patches remove the need for netloop by performing the
copying in netback and only if it is necessary. The rationale
is that most packets will be processed without delay allowing
them to be freed without copying at all. So instead of copying
every packet destined to dom0 we''ll only copy those that linger
longer than a specified amount of time (currently 0.5s).
As it
