Subject: [PATCH 001/222] KVM: PPC: e500: fix allocation size error on g2h_tlb1_map

3.5.7.3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Scott Wood <scottwood@...escale.com>

commit e400e72f250d2567e89c9bafb47ab91e8d9a15a2 upstream.

We were only allocating half the bytes we need, which was made more
obvious by a recent fix to the memset in  clear_tlb1_bitmap().
