Andrew did a great job of merging in the PDA->percpu changes and lguest code for 2.6.21-mm1, but the load_gdt is now unnecessary.

Some concern was expressed over the lguest review status, so I shall send the patches out again for people to review, to test, to make observations about the author's personal appearance, etc. I'll plan on sending these patches off to Linus in a week's time, assuming all goes well. Thanks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body

Thanks to Andrew for pointing these out. This patch moves the parvirtprobe section into .init.data: it's only used in very very early boot, and for similar reasons, puts lguest_maybe_init and lguest_memory_setup in init.text. As well as fixing some warnings, this frees up a tiny bit more memory. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> diff -r ecec388180b2

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

The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to
