Subject: [PATCH 09/14] KVM: monolithic: remove exports from KVM common code

The exports would be duplicated across kvm-amd and kvm-intel if
they're kept and that causes various harmless warnings.

The warnings aren't particularly concerning because the two modules
can't load at the same time, but it's cleaner to remove the warnings
by removing the exports.

This commit might break non-x86 archs, but it should be simple to make
them monolithic too (if they're not already).

In the unlikely case there's a legit reason not to go monolithic in
any arch and to keep kvm.ko around, we'll need a way to retain the
exports. In which case this commit would need to be reversed and the
exports in the kvm common code should then be done only conditionally
to a new opt-in per-arch CONFIG option.

The following warning remains for now to be able to load the kvmgt
driver. These remaining warnings can be handled later.

WARNING: arch/x86/kvm/kvm-amd: 'kvm_get_kvm' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
WARNING: arch/x86/kvm/kvm-amd: 'kvm_put_kvm' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
WARNING: arch/x86/kvm/kvm-amd: 'gfn_to_memslot' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
WARNING: arch/x86/kvm/kvm-amd: 'kvm_is_visible_gfn' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
WARNING: arch/x86/kvm/kvm-amd: 'gfn_to_pfn' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
WARNING: arch/x86/kvm/kvm-amd: 'kvm_read_guest' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
WARNING: arch/x86/kvm/kvm-amd: 'kvm_write_guest' exported twice. Previous export was in arch/x86/kvm/kvm-intel.ko
