On amd64 the pmap code always pins the CPU before calling the shootdown code and expects it to unpin on return. On i386 the pmap code either has pins and unpins around the shootdown calls or does not pin at all. This change should account for that difference. In main and stable/13 the contracts are also different, but the shootdown code is split into the i386 and amd64 variants and each variant is tailored towards the platform's pmap.
