From 8ed7b7e9d2a4e208d3c94af3ddbc628317b30409 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Sat, 22 Jun 2013 17:13:32 +1000 Subject: [PATCH] KVM: PPC: Book3S PR: Fix proto-VSID calculations This makes sure the calculation of the proto-VSIDs used by PR KVM is done with 64-bit arithmetic. Since vcpu3s->context_id[] is int, when we do vcpu3s->context_id[0] << ESID_BITS the shift will be done with 32-bit instructions, possibly leading to significant bits getting lost, as the context id can be up to 524283 and ESID_BITS is 18. To fix this we cast the context id to u64 before shifting. Signed-off-by: Paul Mackerras Signed-off-by: Alexander Graf --- Reading git-format-patch failed
