lguest: Make sure interrupt is allocated ok by lguest_setup_irq

2012-01-12T05:14:47+00:00

Make sure the interrupt is allocated correctly by lguest_setup_irq (check the
return value of irq_alloc_desc_at for -ENOMEM)

lguest: add export.h to lguest files for THIS_MODULE/EXPORT_SYMBOL

2011-10-31T23:32:13+00:00

We need this in advance of the module.h cleanup, or we'll
get compile errors like this:

  CC      drivers/lguest/lguest_device.o
drivers/lguest/lguest_device.c: In function ‘lguest_devices_init’:
drivers/lguest/lguest_device.c:490: error: ‘THIS_MODULE’ undeclared (first use in this function)

lguest: don't allow KVM-detection cpuid.

2011-10-27T00:26:17+00:00

Host might be running under KVM, but we shouldn't allow Guest to think it
can use KVM hypercalls (it can't, and it will embarrass itself if it tries).

lguest: Fix translation count about wikipedia's cpuid page

2011-07-22T05:09:50+00:00

The comment is outdated, wikipedia now has six translations of the cpuid
page.

lguest: remove remaining vmcall

2011-07-22T05:09:49+00:00

We switch back from using vmcall in 091ebf07a2408f9a56634caa0f86d9360e9af23b
because it was unreliable under kvm, but I missed one (rarely-used) place.

lguest: use a special 1:1 linear pagetable mode until first switch.

2011-07-22T05:09:48+00:00

The Host used to create some page tables for the Guest to use at the
top of Guest memory; it would then tell the Guest where this was.  In
particular, it created linear mappings for 0 and 0xC0000000 addresses
because lguest used to switch to its real page tables quite late in
boot.

However, since d50d8fe19 Linux initialized boot page tables in
head_32.S even before the "are we lguest?" boot jump.  So, now we can
simplify things: the Host pagetable code assumes 1:1 linear mapping
until it first calls the LHCALL_NEW_PGTABLE hypercall, which we now do
before we reach C code.

This also means that the Host doesn't need to know anything about the
Guest's PAGE_OFFSET.  (Non-Linux guests might not even have such a
thing).

lguest: fix timer interrupt setup

2011-05-30T01:44:10+00:00

Without an IRQ chip set, we now get a WARN_ON and no timer interrupt.  This
prevents booting.

Fortunately, the fix is a one-liner: set up the timer IRQ like everything
else.
