Subject: kbuild: uapi: completely exclude linux/bpf_perf_event.h on nios2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=60a16beedf37db82edf39346fdc9e3916ab41994;p=thirdparty%2Fkernel%2Fstable.git

kbuild: uapi: completely exclude linux/bpf_perf_event.h on nios2

This header is actually not buildable on nios. As nobody built nios2
with CONFIG_CC_CAN_LINK=y so far, this produced no errors.
