Hi Song,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on bpf-next/master]

url:    https://github.com/0day-ci/linux/commits/Song-Liu/bpf-enable-stackmap-with-build_id-in-nmi-context/20180502-081727
base:   https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> kernel/bpf/stackmap.c:51:1: sparse: symbol '__pcpu_scope_irq_work' was not declared. Should it be static?

Please review and possibly fold the followup patch.
