# Try to include uAPI headers from the kernel uapi/ path.
# Most code under tools/ requires the respective kernel uAPI headers
# to be copied to tools/include. The duplication is annoying.
# All the family headers should be self-contained. We avoid the copying
# by selectively including just the uAPI header of the family directly
# from the kernel sources.

UAPI_PATH:=../include/

# scripts/headers_install.sh strips "_UAPI" from header guards so we
# need the explicit -D matching what's in /usr, to avoid multiple definitions.
