Cover letter [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 a real cpu to run on
- fix a bug where a lazy cr3 reload can prevent a pagetable from being unpinned
- deal with split pte locks properly
- fix an old structure used for the register_vcpu_info hypercall
- add some multicall debugging help
- workaround for a bad XFS/Xen interaction
Thanks,
J
