What: KVM kernel-allocated memory slots
When: July 2010
Why: Since 2.6.25, kvm supports user-allocated memory slots, which are
much more flexible than kernel-allocated slots. All current userspace
supports the newer interface and this code can be removed with no
impact.

What: KVM paravirt mmu host support
When: January 2011
Why: The paravirt mmu host support is slower than non-paravirt mmu, both

Parameters: struct kvm_memory_region (in)
Returns: 0 on success, -1 on error

struct kvm_memory_region {
__u32 slot;
__u32 flags;
__u64 guest_phys_addr;
__u64 memory_size; /* bytes */
};

/* for kvm_memory_region::flags */
#define KVM_MEM_LOG_DIRTY_PAGES 1UL

This ioctl allows the user to create or modify a guest physical memory
slot. When changing an existing slot, it may be moved in the guest
physical memory space, or its flags may be modified. It may not be
resized. Slots may not overlap.

The flags field supports just one flag, KVM_MEM_LOG_DIRTY_PAGES, which
instructs kvm to keep track of writes to memory within the slot. See
the KVM_GET_DIRTY_LOG ioctl.

It is recommended to use the KVM_SET_USER_MEMORY_REGION ioctl instead
of this API, if available. This newer API allows placing guest memory
at specified locations in the host address space, yielding better
control and easy access.
This ioctl is obsolete and has been removed.
