Subject: [PATCH 0/3] kvm: API adjustments for dirty page ring patches

As posted, the patches for the dirty page ring broke non-x86
architectures, because it moved KVM_COALESCED_MMIO_PAGE_OFFSET
incorrectly to include/uapi/linux/kvm.h.

   In file included from include/linux/kvm_host.h:36:0,
                    from arch/arm64/kernel/hibernate.c:19:
>> arch/arm64/include/asm/kvm_host.h:35:0: warning: "KVM_COALESCED_MMIO_PAGE_OFFSET" redefined
    #define KVM_COALESCED_MMIO_PAGE_OFFSET 1
    
   In file included from include/linux/kvm_host.h:31:0,
                    from arch/arm64/kernel/hibernate.c:19:
   include/uapi/linux/kvm.h:218:0: note: this is the location of the previous definition
    #define KVM_COALESCED_MMIO_PAGE_OFFSET 2

This fixes it by moving it to each architecture's UAPI headers
separately.

  kvm: make KVM_CAP_COALESCED_MMIO architecture agnostic
  kvm: make KVM_COALESCED_MMIO_PAGE_OFFSET public
