Subject: [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
- yield if the target vcpu of an IPI is not currently running
- add post-batch callbacks for multicalls [*]
- deal with unpinning pagetables when another vcpu still [*]
has a cr3 reference
- deal with split ptelocks by pinning each pte page
separately under lock
- determine the kernel/hypervisor address split dynamically
- use the right arg structure for register_vcpu_info [*]
- add extra debugging output for failed multicalls
XFS:
- eagerly unmap vmapped areas to avoid confict with Xen
[*] bugfix needed for 2.6.23. I've also cc:d them to stable@...nel.org
