This patch was not tested with 'make headers_check':

usr/include/linux/utsname.h requires linux/kref.h, which does not exist in exported headers
usr/include/linux/utsname.h requires linux/nsproxy.h, which does not exist in exported headers
usr/include/linux/utsname.h requires asm/atomic.h, which does not exist in exported headers

Please protect stuff with #ifdef __KERNEL__ as appropriate, and remember
to run 'make headers_check' before submitting patches.
