Subject: [PATCH v9 01/14] KVM: Rename kvm_arch_flush_remote_tlb() to kvm_arch_flush_remote_tlbs()

From: David Matlack <dmatlack@...gle.com>

Rename kvm_arch_flush_remote_tlb() and the associated macro
__KVM_HAVE_ARCH_FLUSH_REMOTE_TLB to kvm_arch_flush_remote_tlbs() and
__KVM_HAVE_ARCH_FLUSH_REMOTE_TLBS respectively.

Making the name plural matches kvm_flush_remote_tlbs() and makes it more
clear that this function can affect more than one remote TLB.

No functional change intended.
