lguest: fix switcher_page leak on unload

2008-07-28T23:58:32+00:00

map_switcher allocates the array, unmap_switcher has to free it
accordingly.

lguest: comment documentation update.

2008-03-28T00:05:54+00:00

Took some cycles to re-read the Lguest Journey end-to-end, fix some
rot and tighten some phrases.

Only comments change.  No new jokes, but a couple of recycled old jokes.

lguest: fix __get_vm_area usage.

2008-03-10T22:35:56+00:00

Robert Bragg's 5dc331852848a38ca00a2817e5b98a1d0561b116 tightened
(ie. fixed) the checking in __get_vm_area, and it broke lguest.

lguest should pass the exact "end" it wants, not some random constant
(it was possible previously that it would actually get an address
different from SWITCHER_ADDR).

Also, Fabio Checconi pointed out that we should make sure we're not
hitting the fixmap area.

lguest: get rid of lg variable assignments

2008-01-30T11:50:18+00:00

We can save some lines of code by getting rid of
*lg = cpu... lines of code spread everywhere by now.

lguest: make pending notifications per-vcpu

2008-01-30T11:50:13+00:00

this patch makes the pending_notify field, used to control
pending notifications, per-vcpu, instead of per-guest

lguest: per-vcpu lguest task management

2008-01-30T11:50:12+00:00

lguest uses tasks to control its running behaviour (like sending
breaks, controlling halted state, etc). In a per-vcpu environment,
each vcpu will have its own underlying task. So this patch
makes the infrastructure for that possible

lguest: per-vcpu interrupt processing.

lguest: make hypercalls use the vcpu struct

2008-01-30T11:50:08+00:00

this patch changes do_hcall() and do_async_hcall() interfaces (and obviously their
callers) to get a vcpu struct. Again, a vcpu services the hypercall, not the whole
guest

lguest: per-cpu run guest

2008-01-30T11:50:06+00:00

This patch makes the run_guest() routine use the lg_cpu struct.
This is required since in a smp guest environment, there's no
more the notion of "running the guest", but rather, it is "running the vcpu"
