Subject: [PATCH v9 02/14] KVM: Declare kvm_arch_flush_remote_tlbs() globally
There's no reason for the architectures to declare
kvm_arch_flush_remote_tlbs() in their own headers. Hence to
avoid this duplication, make the declaration global, leaving
the architectures to define only __KVM_HAVE_ARCH_FLUSH_REMOTE_TLBS
as needed.
