Right now, I have lguest in-tree module compiling on x86_64. It's not yet on a sendable state, since the module itself isn't loading. However, this subset of the series is pretty straightforward, and I'm sending it now aiming at reducing the delta size in the future ;-) Have fun,

lguest needs to hold a reference to its task in case it exits while another Guest is sending it I/O. Otherwise we can oops in access_process_vm->get_task_mm->task_lock().

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
