KVM: Fix kvm mmu_notifier initialization order

2011-05-22T12:48:12+00:00

Like the following, mmu_notifier can be called after registering
immediately. So, kvm have to initialize kvm->mmu_lock before it.

BUG: spinlock bad magic on CPU#0, kswapd0/342

KVM: Validate userspace_addr of memslot when registered

2011-05-22T12:47:56+00:00

This way, we can avoid checking the user space address many times when
we read the guest memory.

Although we can do the same for write if we check which slots are
writable, we do not care write now: reading the guest memory happens
more often than writing.

KVM: Use pci_store/load_saved_state() around VM device usage

2011-05-21T19:17:10+00:00

Store the device saved state so that we can reload the device back
to the original state when it's unassigned.  This has the benefit
that the state survives across pci_reset_function() calls via
the PCI sysfs reset interface while the VM is using the device.

KVM: Enable async page fault processing

2011-04-06T10:15:55+00:00

If asynchronous hva_to_pfn() is requested call GUP with FOLL_NOWAIT to
avoid sleeping on IO. Check for hwpoison is done at the same time,
otherwise check_user_page_hwpoison() will call GUP again and will put
vcpu to sleep.

KVM: fix crash on irqfd deassign

2011-04-06T10:15:55+00:00

irqfd in kvm used flush_work incorrectly: it assumed that work scheduled
previously can't run after flush_work, but since kvm uses a non-reentrant
workqueue (by means of schedule_work) we need flush_work_sync to get that
guarantee.
