similar to: [PATCH 3/5] lguest: avoid accidental recycling of pgdir pages

Hi, For some days I have been looking for the bug that causes an easily reproducible oops in the guest when I apply my PAE support _draft_ patch (appended at the end of this mail) to lguest. This is the oops: Setting kernel variables...done. Will now mount local filesystems:. Will now activate swapfile swap:done. Cleaning /tmp... [ 84.749676] BUG: unable to handle kernel NULL pointer

Hi, this version requires that host and guest have the same PAE status. NX cap is not offered to the guest, yet.

If we're building a pte, we can use simple assigment; only use set_pte etc. when we're actually going to use that destination as a PTE. I don't know that we'll ever run under Xen, but it's neater. And use set_pte/set_pmd rather than assuming native_ versions, even though that's probably true for most people. (Includes compile fix by Kamalesh Babulal <kamalesh at

This series takes one more step towards cpu-ification of lguest. As for rusty's last suggestion, I get rid of the whole bunch of "struct lguest *lg = cpu->lg" statements around by using lg_cpu as our base structure wherever it matters. (this saves us 11 lines)

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.
