From: Christian Brauner
Date: Fri May 24 2019 - 07:14:22 EST
This wires up the close_range() syscall into all arches at once.

v1:
v2:
v3: added
- Arnd Bergmann <arnd@xxxxxxxx>:
- split into two patches:
1. add close_range()
2. add syscall to all arches at once
- bump __NR_compat_syscalls in arch/arm64/include/asm/unistd.h
