Sebastian Sumpf 7e8661f8bf virt_linux: disable SMP for arm_v7 and change to tiny rcu
When SMP is enabled multicore specific instructions (e.g., pldw) are
generated. These are not supported and lead to invalid instruction
faults on uni-processor systems (like Cortex-A8). Therefore, we disable
SMP for arm_v7 in Linux code. This requires also a switch from the RCU
tree implementation to RCU tiny, which we shadow and dummy implemented.
