Subject: [PATCH] compiler.h: only include asm/rwonce.h for kernel code
This header file is not in uapi, which makes any user space code that includes
linux/compiler.h to fail with the error 'asm/rwonce.h: No such file or directory'
Fixes: e506ea451254 ("compiler.h: Split {READ,WRITE}_ONCE definitions out into rwonce.h")
