- pass ppid from driver to evaluate pid and sid in trace file itself.
- type of apid range change fro

UIO_MEM_PHYS type mem region. The UIO_MEM_PHYS type
is not efficient if dma-capable devices are capable of maintaining coherency
with CPU caches.
This patch adds new type UIO_MEM_PHYS_CACHE for mem regions to enable
cacheable access to physical memory from user space.
