[0/6] KVM: kvm_set_memory_region() cleanups

Message

Cleanups related to kvm_set_memory_region(), salvaged from similar patches
that were flying around when we were sorting out KVM_SET_USER_MEMORY_REGION2.

I'm honestly 50/50 on whether this is all worthwhile, but in the end, I
decided I like having kvm_set_internal_memslot().  I think.

Sean Christopherson (6):
  KVM: Open code kvm_set_memory_region() into its sole caller (ioctl()
    API)
  KVM: Assert slots_lock is held in  __kvm_set_memory_region()
  KVM: Add a dedicated API for setting KVM-internal memslots
  KVM: x86: Drop double-underscores from __kvm_set_memory_region()
  KVM: Disallow all flags for KVM-internal memslots
  KVM: Move flags check for user memory regions to the ioctl() specific
    API
