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
