This patchset contains several improvements for af_xdp socket umem
mappings for 32bit systems. Also, there is one more patch outside of
this series that on linux-next tree and related to mmap2 af_xdp umem
offsets: "mm: mmap: increase sockets maximum memory size pgoff for 32bits"

Based on bpf-next/master

v2..v1:
- replaced "libbpf: add asm/unistd.h to xsk to get __NR_mmap2" on
"libbpf: use LFS (_FILE_OFFSET_BITS) instead of direct mmap2
syscall"
- use vmap along with page_address to avoid overkill
- define mmap syscall trace5 for mmap if defined

Applied, and fixed up typo in last one's subject, thanks!
