Add support for x86 PC systems. This requires the following issues to be addressed: - Various differences in the nv-p2p.h API and semantics. - A different GPU page size. - P2P APIs are implemented in nvidia.ko external module, rather than the kernel itself, so the build system must locate nv-p2p.h and nvidia.ko, and extract required symbol version information from nvidia.ko. - Differences in the allocation routines that CUDA applications must use for memory used with GPUDirect RDMA.
