similar to: [PULL] virtio & lguest changes for 2.6.26

Hi, I am trying to get FreeBSD 4.7 to connect to a Maxtor 5000XT drive, but I get the following when connecting it -> Apr 26 09:19:43 chowder /kernel: fwohci0: node_id = 0xc000ffc1, CYCLEMASTER mode Apr 26 09:19:43 chowder /kernel: firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 (me) Apr 26 09:19:50 chowder /kernel: fwohci0: BUS reset Apr 26 09:19:50 chowder /kernel: fwohci0: node_id =

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().

Because of legacy-induced blindness, I insisted on separately building the hypervisor.S switcher code (which is mapped at 0xFFC0000 in host and guest). However, the lguest64 patches showed the error of my ways: it has no relocations, so it can be linked into the module like normal then remapped. The only downside is that we can no longer use sizeof(hypervisor_blob), so we need to allocate our

Christoph Hellwig said runs sparse: 1) page_tables.c unnecessary initialization 2) Change prototype of run_lguest and do cast in caller instead (when we add __user to cast, it runs over another line). Al Viro pointed out the ugly cast in push_lguest_stack(): 3) Stick with unsigned long for arg, removes 4 casts in total. Most importantly, I now realize that Christoph's incorrect ranting

Kernel pages on x86 are protected by not having the _PAGE_USER bit set. When guest userspace accesses a kernel page, we didn't check this, so we'd think we'd handled the fault and return to the guest, causing the guest userspace program to loop instead of segfaulting.
