From 483ba97c0fafaade3a0ee61217ca5123b0d85c03 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 18 Jan 2013 15:13:19 +0100 Subject: KVM: PPC: E500: Make clear_tlb_refs and clear_tlb1_bitmap static Host shadow TLB flushing is logic that the guest TLB code should have no insight about. Declare the internal clear_tlb_refs and clear_tlb1_bitmap functions static to the host TLB handling file. Instead of these, we can use the already exported kvmppc_core_flush_tlb(). This gives us a common API across the board to say "please flush any pending host shadow translation".
