As promised to Andrew, and with much thanks to Andi Kleen for feedback, this is the new series of lguest patches. Main change is the move to drivers/lguest (for future non-i386 expansion), but lots of cleanups driven by Andi's feedback and the documentation effort (which made me examine every line of code). It's not perfect, but it's definitely useful. Cheers, Rusty. List of

Hi all, Gratefully-received recent feedback from CC'd was applied to excellent effect (and the advice from Matt Mackall about my personal appearance is best unrequited). The patch is split in 5 parts to correspond with the 9 parts Andrew sent out before, but here's the summary: 1) Sparse (thanks Christoph Hellwig): - lguest_const can be static now - lguest.c should include

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
