Scott Wood 1cb4ed92f6 powerpc/e6500: hw tablewalk: fix recursive tlb lock on cpu 0 ... Commit 82d86de25b "TLB lock recursive" introduced a bug whereby cpu 0 uses the same value for "lock held" as is used to indicate that the lock is free. This means that cpu 1 can acquire the lock whenever it wants, regardless of whether cpu 0 has it locked, which in turn means we can get duplicate TLB entries. Add one to the CPU value to ensure we do not use zero as a "lock held" value.
