Merge branch 'renameat2' of git://git.kernel.org/pub/scm/linux/kernel…

…/git/mszeredi/vfs Pull renameat2 arch support from Miklos Szeredi: "I've collected architecture patches for the renameat2 syscall that maintainers acked and/or asked me to queue. This adds architecture support for the renameat2 syscall to m68k, parisc, ia64 and through asm-generic to arc, arm64, c6x, hexagon, metag, openrisc, score, tile, unicore32" * 'renameat2' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: scripts/checksyscalls.sh: Make renameat optional asm-generic: Add renameat2 syscall ia64: add renameat2 syscall parisc: add renameat2 syscall m68k: add renameat2 syscall
